Yes, the regression tests should have failed once you updated to a
"fixed" libxml.

They may have another patch. If you saw your 3.4.1 was still
regressing successfully in the presence of the security updates, it
speaks to maybe the RHEL changes being the security fix and some
perhaps ill-considered other bits that change the behaviour of the
SAX1 parser in the presence of namespaced tags. (which is what broke
our parsing).

[OSGeo-Discuss] GEOS 3.11.0 Released

[Paul Ramsey via Discuss]

Happy Canada Day! 

The 3.11.0 release of GEOS is now available to download at 
http://libgeos.org/usage/download/

This release includes new features for building "concave hulls" for both point 
and polygon input. For polygon input, the hull will be guaranteed to not cross 
into the interiors of the input polygons.

The line merger has been enhanced to support a mode that only merges lines 
which share orientation.

The offset curve algorithm has been updated to be more reliable for different 
kinds of semi-degenerate inputs, and may output different curves than the 
previous implementation, for those kinds of inputs. For "normal" inputs, the 
results should look very much like the old implementation.

As usual, numerous bugs have been fixed, and a few performance improvements 
discovered and implemented.

- New things:
  - OffsetCurve (GH-530, Paul Ramsey/Martin Davis)
  - ConcaveHull (GH-549, Paul Ramsey/Martin Davis)
  - PolygonHull (GH-603, Paul Ramsey/Martin Davis)
  - LineMerger directed option (GH-597, Sergei Sh)
  - CAPI: GEOSHilbertCode (GH-556, Brendan Ward)
  - CAPI: GEOSGeom_createRectangle (GH-558, Brendan Ward)
  - CAPI: GEOSGeom_transformXY (GH-563, Dan Baston/Brendan Ward)
  - CAPI: GEOSRemoveRepeatedPoints (GH-599, Paul Ramsey)
  - CAPI: GEOSLineMergeDirected (GH-597, Sergei Sh)
  - CAPI: setFixStructure for WKB/WKT readers to automatically repair
structural errors in the input (GH-639, Paul Ramsey)

- Fixes/Improvements:
  - Fix unaryUnion to avoid segfault with empty polygon (GH-501, Mike Taves)
  - Fix SnapRoundingNoder to use tolerance in noding; also fixes 
GeometryPrecisionReducer (GH-504, Sergei)
  - Allow direct setting of grid size (GH-513, Martin Davis)
  - Allow GEOS to be used as a CMake subproject (GH-518, Robert Coup)
  - Remove .inl inline files in favour of header declaration (GH-543, Paul 
Ramsey)
  - Add SnappingNoder seeding (Martin Davis)
  - Add OverlayNG area check heuristic (JTS-812, Paul Ramsey)
  - Fix RelateOp (and intersects predicate) for lines with intersections very 
near boundary (GH-570, Martin Davis)
  - Fix IsValidOp to handle repeated node points (JTS-845, Martin Davis)
  - Fix IsSimpleOp to handle closed LineStrings with repeated endpoints 
(JTS-851, Martin Davis)
  - Fix LengthIndexedLine (via LengthLocationMap fix) (JTS-859, Martin Davis)
  - Fix PolygonHoleJoiner (JTS-862, Martin Davis)
  - Improve `test_geos_unit` application error checking and reporting
  - Fix MinimumDiameter getMinimumRectangle for flat input (JTS-875, Martin

Re: [OSGeo-Discuss] avoiding email filters- Poll: Change FOSS4G structure to have some continuity of organization and management

[Paul Ramsey via Discuss]

I am, naturally of two minds about this.

As Sanghee says, the act of pulling together a local conference can be one that 
draws together people from multiple parts of the local geo ecosystem, makes new 
connections that might never be made. Gathering up public, private, and NGO 
sponsors in your local area, and having them all experience the FOSS4G thing, 
something they might not have otherwise gotten to be a part of... it requires a 
local commitment, and local connections, to make it happen. 

Moving to a centralized system, where the locale is primarily a source of a 
venue, an interesting city and some novel culinary options, loses a lot of 
that. I appreciated the turn-key aspect of FOSS4G-NA when LocationTech was 
carrying the organizing load, but the event itself became denatured somehow. It 
lacked the organic connections it had when it was (earlier) in Minnesota or 
(later) in San Diego. 

There will be a loss.

On the other hand (of course), this doesn't come for free. The very uniqueness 
and organicness flows from the "figuring things out on the fly and making the 
connections needed" that local organizers go through. The very thing that 
provides the magic spark, burns them down to the ground.

And the supply of those people, is finite. We've gotten on a long time (at 
least 5 years longer than I would predicted!) with people continuing to step up 
and volunteer for the load. It may be that Covid and the "virtual conference" 
has been what finally killed the supply of enthusiasm. I know myself that part 
of the "fun" of volunteering for the grind was knowing the world was going to 
come to town. When the world is just "dialing in", the sense of reward is (I 
think) a lot lower for organizers. One of the ego-gratifying aspects of 
organizing the conference is being able to see your local contacts go "whoa, 
this is really real, I thought you were always just blowing smoke" as they 
wander through a hall full of 1000 open source geospatial advocates.

Anyways, lots of words to no great conclusion. I think a central organization 
would be more "sustainable" but potentially deterimental to the ethos of the 
thing. Also, very very very very dependent on finding the right resource to 
actually do the centralized work. It could also be a disaster in the wrong 
hands and kill the whole thing dead forever.

ATB,

[OSGeo-Discuss] GEOS 3.10.0 Released

[Paul Ramsey via Discuss]

The GEOS PSC is somewhat amused to set the 3.10.0 release of GEOS free
to fly the skies of the digisphere, bringing valid geometries and fast
operations to entities everywhere.

https://trac.osgeo.org/geos/

Headline changes for this release include:
* Continuing performance improvements, particularly in the in-memory
STRTree, and new C-API functions for reading from / writing to GEOS
objects from in-memory buffers. Because it is a core algorithm for
other processes, the index improvement provides a speed-up to
operations across the library.
* Net-new algorithm for Validity checking that speed up testing of
validity, through a more step-wise approach with short-circuiting.
* A new algorithm for Validity enforcement that uses ring containment
logic to determine polygon area membership, for some "more reasonable"
results in complex ring overlapping cases.
* A triangulation routine for polygons, that provides attractive
constrained Delaunay triangulations.

For those with a nose for details, the full NEWS entry follows.

Thank you for using GEOS,
And your help in its development,
The Whole GEOS PSC

No, we can barely handle the formality around cutting releases without
getting all formal about "long term" versus other stuff. Mostly new
releases are new features and faster old features, and only occasionally is
there anything backwards changing (the 3.9 overlay had some minor behaviour
changes, but not enough to warrant a 4.0 release).

No, we try to backport things that are back-portable, because we recognize
that distros sometimes peg versions, even though upgrading is usually a
safe bet. 3.8.2 is just because that branch had accumulated a lot of fixes
without a release.

[OSGeo-Discuss] PostGIS 3.1.0 Released

[Paul Ramsey]

The PostGIS Team is pleased to release the release [0] of PostGIS 3.1.0!

This version exposes the new features of GEOS 3.9 [1] as well as numerous core 
performance enhancements for spatial joins, large object access, text format 
output and more.

Performance [2] is a key feature of this release, with improvements to spatial 
joins, text outputs [3], large object reads [4], vector tile output [5], and a 
host of smaller tweaks.

The k-means clustering [6] code has been enhanced to support weighting and 
higher dimensional clusters.

Geometry generators to create hexagonal and square tilings [7] have been added, 
for simpler in-the-database summarization queries.

Finally, PostGIS exposes the latest enhancements [8] in the GEOS geometry 
library 3.9 version. The new overlay engine (aka “OverlayNG” [9]) provides more 
robust [10] handling of difficult input geometries, using a set of new noding 
strategies [11] to process geometry. For the end user, this should mean no more 
“topology exceptions” when using the union, difference, intersection or 
symmetric difference functions. PostGIS also exposes the new fixed precision 
overlay capability via an additional grid-size parameter on ST_Intersection 
[12] and the other overlay functions.

Details of this release can be found in the NEWS file:

  https://git.osgeo.org/gitea/postgis/postgis/src/tag/3.1.0/NEWS

To everyone who helped out in testing and developing this release, we extent 
our wholehearted thanks!

Yours,
The PostGIS Team

[OSGeo-Discuss] GEOS 3.9.0 Released

[Paul Ramsey]

The GEOS community is pleased to announce the 3.9 release of the GEOS
computational geometry library. 

http://download.osgeo.org/geos/geos-3.9.0.tar.bz2

The headline feature of 3.9 is the new overlay engine, which is also new 
to JTS. Intersection, union, difference and symdifference all use this
new engine, which provides more robust results than the old engine. 
This should dramatically reduce and hopefully eliminate topology exceptions
when used with valid inputs.

We have continued to work on performance at the C++ implementation
level, and in general hope to demonstrate faster operation for most 
uses.

- New things:
  - OverlayNG engine from JTS, now the default (Martin Davis, Paul Ramsey)
  - MaximumInscribedCircle and LargestEmptyCircle (JTS-530, Paul Ramsey)
  - CAPI: Fixed precision overlay operations (Sandro Santilli)
  - CAPI: GEOSPreparedNearestPoints (#1007, Sandro Santilli)
  - CAPI: GEOSPreparedDistance (#1066, Sandro Santilli)
  - CAPI: GEOSGeom_setPrecision uses OverlayNG (Paul Ramsey)
  - SimpleSTRTree spatial index implementation (Paul Ramsey)
  - Add support for pkg-config for GEOS C API (#1073, Mike Taves)

- Improvements:
  - Stack allocate segments in OverlapUnion (Paul Ramsey)

[OSGeo-Discuss] FOSS4G 2020 Early Paper Deadline is Feb 4!

[Paul Ramsey]

FOSS4G 2020 will be in Calgary, Canada this year, from August 24-29. 
It seems so far away, and yet, the first submission deadline is almost here…

  https://2020.foss4g.org/early-acceptance/

If you submit your talk to the Call for Papers before February 4,  
you will be eligible for Early Acceptance!

  https://2020.foss4g.org/speakers/

Why submit early? We hope early acceptance will help speakers begin 
planning their conference experience earlier, with the certainty 
that you'll be an accepted speaker. Early acceptance also helps 
us build out the program and communicate the value of FOSS4G 
to new attendees.

Help yourself, help us, submit your talk early!
Thanks for your help, 
We're looking forward to seeing you all in August,
Paul and the FOSS4G 2020 program committee

Re: [OSGeo-Discuss] Sol Katz Award - Call for Nominations

[Paul Ramsey]

I'd like to nominate Vladimir Agafonkin, who

https://github.com/mourner

- birthed the most popular open source Javascript interface for mapping,
which has been a gateway drug for javascript and web UI folks around the
internet
- continues to add important javascript geospatial pieces to the open
source world, like the rbush, the simpleheat, and many other small and
useful utilities that people assemble into their solutions in the open
source tradition
- has become a spokes-person for doing lightweight spatial and simple web
development patterns as a means to solving spatial access problems
- killed the chorus in "we're up all night to get mappy" in Nottingham

A community member already with a huge record of contribution and seemingly
no end in sight!

I'd like to nominate Sean Gillies, who

https://github.com/sgillies

- has brought spatial-with-pythonic-principles to the masses of python
users via the popular shapely and rasterio libraries
- had a hand in the birthing and nurturing of the geojson format, including
its recent entry into the IETF
- was an early articulator of rest principles for geospatial and an
important contributor to thinking in that area
- continues to chug away at bringing more spatial smarts into the world of

Re: [OSGeo-Discuss] FOSS4GNA - Someone is watching you :-o

[Paul Ramsey]

Agree w/ Daniel in all ways. We want our events to succeed, no? So we
use marketing techniques to do so. Emails and so on. And we track who
opens them so we can get better at marketing. Like any other business
trying to succeed. Mail chimp is currently convenient, in the past
other technologies were convenient (I spammed people in 2007 using a
custom perl script, because I am a God Among Men), in the future
different technologies will be convenient. But they are all going
towards making a good event.

Naturally the first targets of marketing the event will be people who
have attended past events under the same/similar umbrella. I provided
the 2007 attendance list to foss4g events for a number of years until
it had grown entirely stale. I felt good about it. I revelled in the
goodness of it.

I have spammed. I will spam again, in the service of a good cause.
That is my weakness. That is my strength.

Re: [OSGeo-Discuss] [Board] [Ica-osgeo-labs] The LAS format, the ASPRS, and the “LAZ clone” by ESRI

[Paul Ramsey]

Carl,

No, it doesn't really clarify it. I think what people are wondering is
does OGC have a default mission and position that closed formats are
bad for the industry and would it publicly admonish a member who took
actions that ran counter to that position.  I assume that, as a
member driven organization whose membership includes the offender,
the OGC will not be standing up and publicly saying this company is
contravening the spirit of our organization and mission, that it is
supposedly supportive of.

Am I incorrect?

WRT to OSGeo, I think that black letter cases like this come along
infrequently enough that it would not be at all inappropriate for
OSGeo to publicly state what is wrong with the direction being taken
in the world of LAS formats. The only trouble is, it's exactly what
everyone expects we would do, and therefore will be greeted with a
collective yawn. But it is the right thing, so we should still do it.

ATB,

P.

 Feel free to check OGC email archives, project pages, and so forth for

 Hi Cameron,

 Thank you for this excellent suggestion. I remember this previous
 Geoservices REST API issues and discussions.

 Patrick - Could you please start a wiki page and input as much information
 as you know on this (ideally in the same structure as the Geoservices REST
 API wiki ). Once it is ready, please email the community and OSGeo Board and
 we all can look into this.

 Anyone from OGC willing to help with this?

 I think this should be open letter from the OSGeo Board to the whole Geo
 community. I really hope this proprietary vendor (ESRI) will be decent
 enough to not keep repeating these inappropriate actions in the future.

 Best wishes,

 Patrick, others,
 OSGeo and related OGC communities have been successful previously in
 stopping ESRI's inappropriate creation of OGC standards. See here:
 http://wiki.osgeo.org/wiki/Geoservices_REST_API

 I'd suggest that if we as OSGeo wish to be effective at blocking a vendor
 lock-in tactic, as seems to be the case, then we should consider developing
 a similar wiki page for the LAS format debate.

 0. Write an open letter (who to? OGC?)
 1. Describe the issue. (Is there someone who knows the issues well enough to
 describe them?)
 2. Describe technically why one format is or is not better than the other,
 on both a technical and commercial point of view.
 3. Is the Open LIDAR format an OGC standard?
 4. If needed, collect signatures.
 5. If needed, ask OSGeo Board to present the open letter

[OSGeo-Discuss] FOSS4G Organizing

[Paul Ramsey]

I have two contradictory positions wrt LocationTech and event organizing, and 
I’ll start with this one, since it’s easier: as long as the organizations are 
separate, I think that OSGeo should maintain its own brand and use a 
professional organizer that is 100% dedicated to OSGeo without any conflicts of 
interest, perceived or otherwise.

There are a number of places to start in finding such a corporate partner for 
event planning. An obvious thing to do would be to look at other successful 
international technology events in our space and who organizes them.

 
http://www.ieee.org/conferences_events/conferences/organizers/conference_organizer_contacts.html
 https://us.pycon.org/2014/about/staff/
 http://events.linuxfoundation.org/#event-services

If nothing else, folks at those organizations could refer us to other companies 
we may not have heard to so we could run a real competition for our business.

Since getting involved in a commercial relationship like this is a big, 
existential decision for the organization, I think it falls to the board to 
decide

(a) if moving to a single professional event organizer for all major foss4g 
events (international, na, eu) is warranted
(b) if so, assigning a small team to speak with the alternatives, and bring a 
concrete decision in the form of a recommended company and contract terms to 
the board

It is important to get a decision on (a) as quickly as possible, as the venue 
decision for 2016 will have to be made and which organizing principle it falls 
under is important to establish sooner than later.

 Both simpler, and better for the bottom line of OSGeo, if you want to

 foss4g.

 Yes Paul, pay for membership is simple, but I'd argue that the value of 
 OSGeo and OSGeo communities is the volunteer time we contribute, and pay 
 membership wouldn't capture that.

 This property is the nature of a professional organization, which in my 
 opinion, OSGeo clearly is. There are a number of strong reasons why small 
 annual fees for membership are very attractive. The first is there's no 
 struggling with members who've dropped off, haven't voted, are no longer 
 participating. Second, anyone who wants to associate themselves can simply 
 do so by paying dues. Finally, a consistent, if small, operating revenue.

 The voting process has been an ad-hoc affair since the beginnings of the 
 organization. Every year it the rules are tweaked. Every year members who've 
 dropped off need to be nagged. Every year we end up just taking everyone 
 who's nominated anyway. It's a lot of overhead and volunteer cost for very 
 little gain.

 It is certain there are people who wish to be professionally associated with 
 OSGeo who are unable to become members because they haven't generated enough 
 public profile to be nominated. You can't nominate yourself. It's a chicken 
 and egg problem that simply dissolves with paid-but-small membership dues.

 OSGeo's main revenue stream is the FOSS4G conference. It is an event run on 
 the backs of local chapter volunteers. Please correct me otherwise, but I do 
 not think any local chapter who has hosted FOSS4G has ever put in a proposal 
 to host it again. This well may eventually run dry. Or, it may run dry for a 
 year or two. 80-100k/year (~$50-70/year * 1500 persons) of membership dues 
 is plenty to keep the lights on through droughts and still allow the 
 organization to move forward.

 At the inception of the organization, a driving factor toward our current 
 membership structure is because OSGeo is a volunteer organization, it 
 shouldn't require members to pay money. I think this is misguided. Every 
 other professional organization of which I'm a member requires membership 
 dues. As an IRS classification, a professional organization has a clear path 
 forward.

 I am a professional open source Geo/GIS software developer. I want to belong 
 to a professional organization that represents me. I would be happy to pay 
 some nominal membership dues that a) signify my membership, b) provide 
 financial buffer for the organization to achieve its mission, and 3) clearly 
 signal what the rules are to become a member.

 My $0.02.

 Howard

 1/ I think that whatever change in the election process should be validated
 by the Charter Members themselves, so I fully agree with Arnulf that we need
 to vote on that and not just the Board. And of course this contains no
 offense for the Board; it is just that I think that it is fair that the body
 who is affected by the changes to take the decisions.
 Moreover the charter members are the ones who elect the Board so it seems
 quite awkward to me that the smaller governing body will take such decision.
 2/ I think that whatever decision taken should be enforced in next year's
 elections; members need some time to evaluate that. So it is good to
 conclude this process now but enforce it from next year.

 (B) the proposed changes:
 Before discussing the proposed changes I think that we should understand
 where the current system has failed. Do we have cases where recognized
 community leaders failed to be elected? If so please bring them forward. I
 doubt so though since if I recall correctly the last two years all charter
 member nominations were accepted without voting! Moreover the notion of a
 recognized community leader that cannot be elected as a charter member is
 a contradiction by itself. So why change?
 I am not against the idea of having some people becoming OSGEO Charter
 Members ex officio but for one I do not like the idea of having members of
 different categories and secondly I need to have a look at the data: how
 many of the committee chairs, PSC members, official Chapter chairs are not
 already OSGEO Charter members (and they wanted to be and failed)? Why are
 they not nominated to become ones and to be voted?
 And I don't see how the problem described here:
 In previous years the Charter Member selection process has been a little
 contentious. We typically receive numerous nominations from high caliber
 members of our community, and insufficient positions to accept them all.
 This typically results in unnecessary disappointment and dissent.
 will be resolved: again we will have some people not becoming Charter
 Members if the seats are not enough. So some of us will still be
 disappointed, etc. So if the numbers are the same the only difference I see
 is that now we choose beforehand whom to disappoint and people working in
 the community but in not official positions will have less chances to be
 elected.
 If we want to open up the numbers, this is OK, more seats are offered every
 year anyway. But what else?
 And of course the first come first served approach if the recognized
 community leaders are more than the seats is a bit odd: to lighten up the
 discussion I cannot imagine people with the finger on the mouse waiting for
 the process to open in order to submit there nominations.
 Finally, for the voting process I completely disagree with the ability of a
 member to vote multiple times for the same person. This removes from the
 process the requirement of someone to be widely recognized within the
 community and potentially allows a couple of friends to elect whoever they
 want.

 I think that the discussion is interesting and thanks to the board and
 Arnulf :) for initiating it!
 I think that other solutions could also be considered if we feel that we
 need to differentiate on how charter members get elected, e.g. agree on a
 bonus percentage that a community leader gets when he goes through the
 standard process, so he still has to be voted by many...

 I apologize for the length of the e-mail and thanks for listening,

 Best regards,

 Dimitris Kotzinos





 Within 2 weeks we intend to start our annual process for selecting new
 OSGeo charter members.

 In previous years the Charter Member selection process has been a little
 contentious. We typically receive numerous nominations from high caliber
 members of our community, and insufficient positions to accept them all.
 This typically results in unnecessary disappointment and dissent.

 In response, the OSGeo board has agreed to trial tweaking the voting
 process. The aim is to automatically accept recognised OSGeo community
 leaders, while continuing with our existing process which attracts the
 many valuable community members who contribute in other ways. Community
 comments are encouraged, and will be considered over the next week.

Re: [OSGeo-Discuss] FOSS4G 2013 Nottingham Update

[Paul Ramsey]

+10, the workshops selection is always contentious, and there are
always people disappointed, since the number of slots is so limited.
It's a difficult part of the organizing process to make and stand by
those decisions. I'm glad Barry is working on his optimization
algorithm, so we can finally put this annual problem permanently to
bed :)

 Hi all,

 As a previous FOSS4G chair I would just appeal to everyone to go easy on the
 organizing team. I was not involved in the selection process this time but I
 do know there was a high number of workshops that were submitted, so
 unfortunately half the submitters are going to be disappointed and think
 that the committee made the wrong the choice.

 Barry also stated that he wasn't involved in workshop selection, so you
 really shouldn't all be reading lots into his side comment that the
 workshops present good value - my interpretation is that was just a general
 comment that was Barry's opinion and nothing to do with selection criteria.

 Also the reality is that there are so many submissions that you can't give
 specific reasons to everyone who was rejected why they didn't make it - this
 would hugely increase the already large amount of time that all these
 volunteers are putting into creating a FOSS4G event, and make a difficult
 process even more difficult.

 Just a few thoughts as a previous organizer :)

 Cheers,
 Peter.

 It would have been nice if we'd had feedback on the reasoning behind that.
 Considering about half the national INSPIRE geospatial catalogs in Europe
 run on the product I consider it a relevant OSGeo product. Reading the

 If we couldn't swing a self-hosted event I think there is a good change I

 My employer might be willing to help sponsor some of the costs for a

 I think you should try to organize a committee to bring Foss4g NA to the

 At the project-level Hayashi is a member of the ZOO Project PSC (often

 changes in several OSGeo projects.

 I believe Hayashi will be a great voice from the vibrant Japan chapter.

[OSGeo-Discuss] FOSS4G 2013 RFP Result

[Paul Ramsey]

Conference Committee, Bidders,

Good morning (PDT). The results have been tabulated, and every member
of the committee has voted (yay).

Many thanks to both teams for bidding. Many of the members commented
on the difficulty in selecting a bid, given the quality and attention
to detail in both bids.

The voting results are

Nottingham 8
Helsinki 2

So, FOSS4G 2013 will be in Nottingham, UK.

To the Nottingham team:

- The sooner you can carve your dates into stone, the better for
promotion and planning
- Remember that you will have to submit a budget to the Board for
approval, and the Official, Really for Reals Acceptance of your bid
is contingent on the Board formally accepting your budget and bid.
Let's move that process forward briskly.

To the Helsinki team:

- You had a great bid and a wonderful venue and plan, I hope you'll
consider bringing your preparations and research to hosting an EU
Regional event for 2014.

Thanks again to everyone,

Paul,

Re: [OSGeo-Discuss] [OSGeo-Conf] regional conferences

[Paul Ramsey]

On Mon, Jun 18, 2012 at 5:08 AM, Steven Feldman shfeld...@gmail.com wrote:
 If there are regional events in every continent except for the continent
 where the global event is being run we may risk diluting interest in the
 global event.

 We will have the global FOSS4G in Europe in 2013 (either UK or Finland will
 host) we would expect to see less delegates from outside of Europe if there
 are North American, Asian and other regional events.

 Perhaps a compromise would be to ensure that the timing of regional events
 is as close as possible to 6 months away from the global event?

That's always a risk, but the reality is that the vast majority of
FOSS4G attendees are from the local region, and only a small slice are
international. So we really are effectively serving a much larger
population with regional events. In some ways (watch this rhetorical
bend) dilution is actually a net positive, because it keeps the
same-old-same-old highly rated software talks from clogging up the
agenda leaving little space for quirky local topics.

But I digress.

I've been encouraging the regional organizers to try and keep as much
schedule space between their event and mid-September as possible. This
I think helps the international travellers make schedule time to
potentially attend two events in a year.  It does lead to some awkward
moments though, like FOSS4GNA this year coming just 6 months *after*
the last event in NA, the Denver conference. All in all though,
because we were serving a market (DC) that itself couldn't all get
even so far away as Denver, we ended up serving a wider group.

So I think on balance the regional thing is serving us very well. It
pains me to say it, but we might be better off de-emphasizing
FOSS4G-the-international-event and trying instead of space regional
events regularly around the calendar so it's possible for some
in-demand speakers to hit 2-3 regional events, while still allowing
more travel-constrained local delegates the option of having a regular
event.

So many options, but unfortunately there's no slam dunk way of knowing
what is best.

 Nice to see that Opengeo suite offers several Licenses of support.

 Just wish some clarity
 1. Free downloads (and self teaching) continue ?

The community edition will always be free to download. The enterprise
edition will require registration for an evaluation. The OpenGeo
workshops (workshops.opengeo.org) are free with registration.

 2. The License is still GNU GPL?

Yes. All components are GPL or LGPL.

 3. A license is good for getting support, but one can do without the same,
 if competent enough..!!

We imagine our market is not individuals (who often have competence
but generally no budget) but rather organizations, whose access to
competent individuals ebbs and flows as they enter or leave the
organization, but sometimes do have budget to buy a guarantee of
access to competence (us).

 OpenGeo Suite is probably a landmark development in WEB-GIS.. and going

 I also feel that some form of active pursue of funding has to happen. 
 Voluntary initiative to donate funds are a noble approach but one that spurs 
 little participation.

 It seems clear there is a dividing line where we start to give a negative 
 impression and that should be avoided at all costs. But a well written 
 letter directed/personalized to specific organizations that are known to be 
 big/strong adopters should be well received, and met with a significant 
 success rate. It's not a shakedown, it's a plea for help.

 This or any other variant for that matter. The key is doing active pursue of

 Assunto: Re: [OSGeo-Discuss] Are there proposed ways to raise funds for 
 OSGeoprojects?

 Duarte,

     I agree with you and have similar ideas.  I just recently sent an email 
 similar (cites National Public Radio and Wikipedia examples) to these ideas 
 to the Board.  http://lists.osgeo.org/pipermail/board/2011-June/003816.html  
 The premise of my idea is that there are numerous agencies and companies 
 that have employees with minor budgetary authority to spend ~$500 on 
 software and these individuals are often using OSGeo projects and getting 
 assistance using these OSGeo projects on the email lists and IRC.  It makes 
 sense that these people might be involved in sponsorship.  What do others 
 think?

     Although not heavily promoted, OSGeo and some projects can accept money 
 through OSGeo here, http://www.osgeo.org/sponsorship/opportunities  Some 
 have $500 minimums.

     Here is the content of that email:

 Board,

 I started this email about six months ago and wanted to keep refining it and 
 adding bits, but, it seems to be the opportune time to send it since it is a 
 current topic for the Board (and it is already far too long - perhaps I 
 should have spend more time removing not adding).

 I have some ideas pertaining to fundraising that I did not find previously 
 discussed on the board or fundraising email lists.  Searching the wiki and 
 board minutes didn't turn up this discussion either.  Perhaps these ideas 
 have already been discussed and discarded in other venues.  I think that 
 OSGEO projects could get substantial funds from many corporate and agency 
 users in $500-$2,000 increments on an annual basis.

 I am thinking of a fundraiser very similar to the National Public Radio 
 style in the States.  That is that for one week instead of providing high 
 quality, commercial free, respected news and music, they focus at least 50% 
 of the time on fundraising.  In addition to changing the focus to 
 fundraising they use all methods possible to fundraise.  The methods seem 
 almost extreme.  It verges on berating, guilt, coercion, and other less 
 dignified methods.  Here are some clips that highlight some of these methods 
 although mixed with humor, http://www.vpr.net/episode/49677/  If you have 
 never listened to a NPR style fundraiser, I would suggest listening to one 
 (although I also suggest listening to the station for a week without 
 fundraiser to experience some of the more positive aspects of NPR).  There 
 should be one on internet radio currently, perhaps someone can send out a 
 link when their local station is fundraising.  In all the fundraising the 
 focus is that NPR provides unique, high quality, commercial free, respected 
 news and music and that you, yes you, can help provide that unique, high 
 quality, commercial free, respected news and music that you and others value 
 so much.  This is impressed upon you in that familiar authoritative NPR 
 voice which you have come to trust and respect over the years.

 NPR has the benefit that people listen to the radio for extended periods of 
 time at home, at work, and in the car going places.  To adopt that approach 
 to OSGeo, would be project mailing lists, IRC channels, websites, 

[OSGeo-Discuss] 2010 Charter Member Selection

[Paul Ramsey]

OSGeo members,

The 2010 process is complete, and the new charter members are, in
alphabetical order:

• Alex Mandel
• Andreas Hocevar
• Anne Ghisla
• Astrid Emde
• Danilo Furtado
• Gavin Fleming
• Hirofumi Hayashi
• Jo Cook
• Maria Brovelli
• Milena Nowotarska

I apologize for not sending out more process reminders, but I was on
the road in Japan and not really watching the clock. However, the
voting period has now passed, and over 50% of the membership
participated in the selection process.

Thanks to all the nominees who took the time to write to the discuss
list about their nomination.

A significant number of voters expressed that the number of slots was
not sufficient given the number of quality nominees, which is an issue
I will refer to the Board for next year's process.

Thanks for your votes,

Re: [OSGeo-Discuss] Help authoring tools

[Paul Ramsey]

PostGIS is docbook, a decision from Way Back.

Docbook has served us well, and in particular has provided some
unexpected benefits, in that the detailed markup have allowed
documentation-driven test frameworks to be built (we can actually
automatically test every documented function).

That said, if I were making the decision again today I'd use RST and
Sphinx, for the attractiveness of output and the human-readability of
the documentation source. It's easier to update the documentation at
source when you can easily visually scan it. I found I couldn't write
large chunks of docbook without using a WYSIWYG editor like (now
defunct) XMetaL.

  Daniel,

 MapServer, GeoTools, OpenLayers, GeoServer, Shapely, libLAS, and GeoDjango 
 all use Sphinx http://sphinx.pocoo.org/.  In my opinion, Sphinx's great 
 advantages in order of importance are:

 - text-like markup (docbook is too much burden on documentation writers).  
 Restructured text is not too difficult to learn, but I wish the world would 
 agree on a text-like markup (markdown, restructured text, wikitext, etc)
 - variety of output.   Besides html, you can do ePub, PDF (multiple ways -- 
 via latex or stand alone), windows compiled help, qthelp, man
 - pretty output
 - simple installation and management

 I know there are some sphinx skeptics from the MapServer project on this list 
 who might chime up one way or another about its level of success within the 
 MapServer project, but I think its implementation has help our project 
 immensely.

 GDAL is still using Doxygen for its documentation generation.

 guys http://www.assemblysys.com/dataservices/db_details.php?db=3 are
 distributing a database with cities geographic positions but this is PAID :(
 . What I wanted to know is if there is any tool/software/database free, open
 source where I can do exacly the same without having to pay for that. And
 even, maybe add a few cities positions and contribute to the project

 Thank you

 Hi,

 First, sorry for cross-posting to anyone also on the gvSIG-International
 List.

 I just received a CD, and regularly receive CDs, with ~100 1km x 1km ECW
 Tiles as part of a contract. Does anyone know of a routine to scan these
 files or their associated header files and creates a shapefile showing the
 extent of each image?

 I sort of imagine running the routine, being asked to specify the directory
 containing the image data then having a polygon layer appear with the extent
 of each tile. The attribute table would be populated with layer name,
 coordinates, and any other metadata that can be gleaned from the files.

 A couple of links to reviews of desktop clients at:
 http://wiki.osgeo.org/wiki/Case_Studies#Review_of_Open_Source_Desktop_Clients

 In particular Stefan's summary of clients is the best I've seen so far.
 http://www.spatialserver.net/osgis/ is quite comprehensive.

 The steps I see toward kicking off a Desktop comparison at FOSS4G are:

 1. One person to step forward and offer to drive the comparison through to
 completion. (This can be a couple of people, but it usually starts with
 one). Effectively act as a project coordinator, setting up wiki pages,
 contacting potential parties, ensuring scope is capped. Paul Ramsey, Andrea
 Aime and Jeff McKenna seemed to be the driving people behind the WMS
 shootout. If you are reading this and think you might be able to fill this
 role, then please speak up.

 2. The key projects need to be contacted, and at least one volunteer
 identified for each project. Ideally, there will be at least 3/4 of the
 projects represented. Within a year or two, any potential gis desktop user
 will start their search for clients by reviewing the results of the Desktop
 shootout, so projects represented in the shootout will become the dominant
 projects. (This is why it will be important for projects to get on board)

 3. Between the volunteers, and led by the coordinator, a set of benchmark
 tests should be set up. This will probably include a core set of tests that
 everyone should do relatively easily, and optional tests that each project
 can do to show off their application.

 4. Lots of hard work setting up environments, and running tests. Hence it is
 important to start early if we want to have a good showing at foss4g.

 5. Just before foss4g: Pens down, collate results, present.

 Hei all,

 thanks for Cameron on keeping me in the loop, and to Markus for
 remembering :)  I am now subscribed to this list.

 I think Pauls idea sounds interesting - because this whole comparison
 thing is
 a) quite cumbersome when we have 10 desktop GIS (+ X), and
 b) neither really worth because desktop GIS are used for a multitude of
 tasks, while web map Servers or databases aren't that much - right?

 So as Paul is quoted on the osgeo wiki: one needs to set up use cases
 first (just wrote that today in a new article too, which contains a section
 on selecting free GIS software). And I also discovered that just most of the
 projects have a different focus during my evaluation. Which of course does
 not mean that such thing should not be presented - but it must be focussed
 in some way or the other to have a benefit. And as a side note, I am not
 sure if measuring processing times makes sense either, as GIS analysis
 feature sets are so different.

 However, I am in for testing with OpenJUMP.

 Two more notes:
 - my comparison tables are now already 2 years old now (from 2007), i.e.
 need some update (but the last pub in Ecological Informatics took into
 account newer developments too, but is superficial and focused towards the
 average GIS users).
 - I gave a talk about this at OGRS:

Re: [OSGeo-Discuss] code sprint before or after the conference

[Paul Ramsey]

Pick your poison. Before, people are jet lagged and worrying about
their talks. After, people are tired and worn out. I would continue to
go with a one-day event after. One day is good for sitting down and
talking, less good for coding, but the communication is really
important.

At the 4-day sprint in Toronto, day 1 was mostly used for talking. I
think if you want an event that turns out lots of new/fixed code, you
need more time, and more fresh people, which means logistically tying
it to FOSS4G is never going to be a great idea. Bolsena, Toronto,
those are the models that seem to work.

That kind of high-touch approach will have to be left to those (like,
hopefully OpenGeo) who are building and monetizing products around the
core software. The non-profit core organization can't do that unless
it's willing to become much more vendor-like, which is something OSGeo
has repeatedly shied away from (perhaps because OSGeo has many members
who work for companies, that, like OpenGeo, are monetizing open

So hung up on wavelets, we are.

Internally tiled TIFF with JPEG compression and similarly formatted
internal overviews can achieve 10:1 compression rates without
noticeable image quality reductions, and as an added bonus can be
decompressed a heck of a lot faster than wavelet-based formats. The
wavelet stuff is k00l, in that there is no need for an overview
pyramid (it's implicit in the compression math) and much higher
compression rates can be achieved. But operationally, you can go a

algorithm) approach.

 Paolo,

 The problem is a volunteer manpower one.  There are definitely plans, it is
 just a matter of finding the time in which we can shut down and implement
 them.  I'm sorry that I can't give a better answer than that.  If you have
 time you can devote to the effort, please join the SAC list, and we can get
 you up to date with all of the issues.  We would happily add another
 administrator of Trac if you have lots of familiarity with it (especially
 mod_python, mod_wsgi and sqlite{1,3} vs external db like pg).

 Hey-

 I'm hoping to hear some discussion that results in the creation of
 guidelines for new, pre-incubation projects wishing to assign copyright to
 OSGeo.

 Ideally, these guidelines would be as simple as:
  1) Follow instructions for becoming a labs project
 http://wiki.osgeo.org/wiki/OSGeo_Labs
  2) Follow instructions on assigning copyright
 http://wiki.osgeo.org/wiki/Project_Copyright_Assignment

 Both of the above pages would require some modification.

 I'd suggest a section on the labs page about becoming a labs project
 (perhaps as simple as editing that wiki page).

 On the copyright page, it would be nice if the preferred template replaced
 the old one and if there were some instruction on what to do with a signed
 agreement (e.g. mail to X).

 Does this seem reasonable?

 This has been brought up previously ([1], [2]).  Previous suggestions have
 been don't ask, just assign and ask existing project to accept
 governance.  Since the former feels sleazy and the latter assumes some
 existing project is motivated to assist the new project, I'm hoping there
 can be something in between.

 Also, since I don't pretend to understand all the implications of assigning
 copyright, I would accept OSGeo doesn't encourage this as an answer.

 Thanks for any ideas (and I'm happy to help with drafting any guidelines).

Re: [OSGeo-Discuss] Relationship between Telascience and the OSGeo

Amazon perhaps. Google might find it cuts a little too close to the
bone. Chris, have you approached the AWS folks about hosting OAM? It's
a little more involved than just data storage, they'd also need to
provide a couple EC2 instances to receive and process the new data,
but it would remove the hosting and scalability issues nicely.

 Wow! Does our traffic require two dedicated servers like this?

 Landon,

 The arrangement at Peer1 was made primarily with the goal of having
 a reliable decent server able to support svn/trac and related project
 services.  The second server is primarily serving as a backup though
 the wiki is hosted there.

 We are contemplating dropping use of the second Peer1 server to save
 funds.

 Large scale geodata hosting is pretty demanding from a computational,
 disk space and bandwidth point of view and it would be likely be
 cost prohibitive for us to pursue it in a big way on commercially
 priced servers like the ones at Peer1.

 Is it the space requirements that make geodata hosting demanding, the
 bandwith requirements for download, or both?

 Both.  Bandwidth overages at Peer1 can mount up to be expensive very
 quickly, so we already host our most bandwidth intensive applications
 (download.osgeo.org and existing geodata services) at telascience.

 I'm presuming the hosted data would be made available as web services
 (WMS, WCS, etc) not just a download site.

 Frank wrote:  There is some question in my mind just how central the

 It would be great to get this clarified.

 Clarifying such a matter is not trivial in an organization with
 many different ideas like OSGeo.

 I had originally asked this question because I might be able to make a
 small donation to support free geodata hosting. I was trying to figure
 out which organization would be the best suited for the donation.
 Sounds
 like it should go to telascience. We'll see how my taxes works out
 this
 year. :]

 I'm not sure if telascience accepts public donations or not, nor whether
 it is 501(c)3 which might matter for tax purposes.

The data is chunked in Oracle into tiles, so unless you tile the TIFF
as well you aren't really doing a direct comparison. Even if you end
up with the same numbers for both processes, I'll still be impressed,
since I assumed Oracle would have a higher overhead.

 Hi There,

 I would like to return to a discussion that we had months ago about raster on 
 RDBMS. But this time I would like to present some number.

 As long as I could recall there was basically two major arguments contrary to 
 storing raster on RDBMS. One very pragmatical: Why waste precious process 
 time with the overhead of dealing with queries, tables, client-sever back and 
 forth just to get the data from BLOB fields on a database when you can get it 
 directly from the file system?. The other argument was semantical: Why 
 store raster on RDBMS if in general we are not expecting to have a 
 transactions on that data?

 I cannot argue against the second one. I basically agreed with that but after 
 seeing how fragile and complicated even a well defined structure of folders 
 and files could be I would vote in favor of the good and old relational model.

 That is my experiment. I downloaded two free data samples from Naveteq 
 website. Two geotiff files with the same size and number of bands (14336, 
 14336,  3):

 [EMAIL PROTECTED]:~/Data du -k Barcelona_2007_R2C2.TIF
 602828  Barcelona_2007_R2C2.TIF
 [EMAIL PROTECTED]:~/Data du -k San_Francisco_2006_R1C2.TIF
 602828  San_Francisco_2006_R1C2.TIF

 Then I loaded those images to Oracle Spatial GeoRaster using GDAL. The 
 loading process is comparable than some commercial ETL products on the 
 market. It took about 2 minutes to load each image.

 [EMAIL PROTECTED]:~/Data time gdal_translate -of georaster

 If you are a Oracle GeoRaster users you might be excited about those number 
 already but those are not the numbers I want to show. What I would like to do 
 is to compare the time that it takes to extract subset from the original 
 geotiff and compare with the time to extract the same subset from the RDBMS. 
 He are the numbers:

 [EMAIL PROTECTED]:~/Data time gdal_translate

 I'm strongly in favor of the former.

 For one, like Cape Town, Sydney is too long of a flight to make it just
 a trip about the conference, in my opinion. We had an organized group do
 a two day trip down the cape after the Code Sprint in Cape Town, and I
 think it was a really successful bonding experience for those of us who
 came along, allowing some non-coding social time where we all go to hang
 out and know each other a little better, which I expect will help
 develop better communications in the coming months within the project.

 Also, having a break between the conference after the code sprint keeps
 the possibility of having a 'finished' result of something by the
 conference more likely as well. In general, code sprints are good at
 producing a lot of unpolished code: a couple days can help to get the
 code a bit more polished in order to present it as a new development
 during the conference, if people so choose.

 Lastly, I think that having a break before the conference gives people a
 bit of time to unwind: code sprints tend to be exhausting if you do them
 right (taking full advantage of shared physical location with long
 hours, for example), and going directly from that into a conference
 (described by one attendee as being similar to 'a 5 day long rave' due
 to the amount of energy it consumes) feels dangerous. :)

going to be filling out their lessons learned pages, but I think it
would be great to get some informal feedback that future organizers
can use to avoid pitfalls and repeat slam dunks in future events.

I've put two pages in place, for those with long memories:

  http://wiki.osgeo.org/wiki/FOSS4G2007_Comments

And for you recent returnees:

  http://wiki.osgeo.org/wiki/FOSS4G2008_Comments

So you have a place to fill out your impressions. If you see something
you agree with, add a +1.

Re: [OSGeo-Discuss] Code Sprint: How Much?

[Paul Ramsey]

I've been thinking about something similar to the Bolsena event in
North America, but it's hard to work out a scheme that will be
productive, given the geographic dispersal of folks. I think a C
tribe sprint would be excellent, but we're pretty spread out (though
biased towards Ottawa / Quebec). Anyone want to rent a chalet in the
Gatineau hills?  I'll burn some frequent flier miles to come to *that*
:)

[OSGeo-Discuss] C++ Expert Wanted (GEOS)

[Paul Ramsey]

I have a client who desperately wants to clean some memory leaks out
of GEOS in a relatively short time frame. If you have enough C++ chops
to wrestle with the GEOS code base (warning, non-trivial and not
exactly a french garden) and some time over the next few weeks, let me
know.

[OSGeo-Discuss] Code Sprint: How Much?

[Paul Ramsey]

Everyone loves a good code sprint... or do they?

2007 brought you the one-day sprint (with the GeoToolsers and uDiggers
going for an extended weekend sprint).
2008 brings you another day.
2009 is still thinking about it.

How much sprinting would you do? 1, 2, 3, 5, 7 days?

I am wondering if the right way to handle the sprints is to turn them
from something the conference quietly subsidizes to something that
OSGeo pays for directly.  That way the conference organizers don't
feel like they are having it taken out of their hide, and it can be as
long as people like. Also, it fits directly into the OSGeo mission of
promoting the development of the software.

Book-keeping-wise it's a left-pocket-to-right-pocket transaction for
OSGeo, but from a authority and decision making PoV it removes the
issue from the plate of the conference team and puts it into the hands
of the software promoting team (whomever they may be).

[OSGeo-Discuss] This List

[Paul Ramsey]

Is, anywhere on the main web page, prominent mention made that
basically all important announcements end up on this list (but not
necessarily in the web site news feed, for example)? At
lists.osgeo.org, this (very important) list is one among many many.

Ah, I see there is: Main - Getting Started - Mailing List FAQ

I worry that we are a little, er, inbread on this here list.

Re: [OSGeo-Discuss] This List

[Paul Ramsey]

OK, I take it back, news_item appears to be working. More to the
point, discuss@ is referred to as sort of a tribune of the people on
occasion (let's ask discuss!) when really it's sort of a private
club.

 Paul,

 Important announcements should be making it to the announce list.
 What is an example of important announcements made only here?

 Best regards,

 Hi,

 Interesting article.

 I am surprised not to see JTS even mentioned in this brief history, as it is
 a founding library which has been used in some way by most of OSGEO
 projects.
 Martin Davis could say when it was released for the first time.

[OSGeo-Discuss] URL

[Paul Ramsey]

project.osgeo.org

During ColabNet days, we had this scheme, but it was dropped when we
moved. Was there a reason for it? I personally feel some love for it,
since it allows things like bringing the Mapserver site into osgeo.org
with a simple URL change.
