Dear all 

Regarding the FOSS Geodatabase discussion, I would like to bring a different 
issue to the discussion.

It concerns whether we should be concerned with broadening the number of FOSS 
databases that offer support for spatial data, or whether we should focus on 
deepening and increasing the support for different types of spatio-temporal 
data on PostGIS. 

Consider a situation where PostGIS would demonstrably handle more spatial data 
types than Oracle and would do so efficiently. This would provide a tremendous 
leverage for all FOSS4G applications and developers. 

To me, PostGIS is to FOSS4G what Linux is for FOSS as a whole. It's the 
enabling platform for succesfull FOSS4G enterprise applications. By 
concentrating on PostGIS and associated tools, we will build a reliable and 
consistent set of tools. 

Best regards,
Gilberto

...Hi Landon,

a)  It's not a podcast (but still a ...cast, and it's
fresh...subcribers of the Italian mailing lists, my apologies for
re-posting):

http://www.youtube.com/watch?v=_ZOQSn5tyqQ

This is a sort of "teaser" video on GIS and the role that awareness
raising organizations may play in promoting FOSS GIS (eventually
talking about GFOSS.it for Italy).

The message is directed to people who are not typical OSGeo discussion
readers ;) , but I'd still appreciate feedback from the list.

Maybe you can find some ideas of use for an introduction...

b) I'd like to have more "episodes" gradually delving into more
substantial topics, such as applications etc...time and resources
allowing....
I'll be keeping an eye on material you may develop -and other links
which are being flagged out- as they may be a starting point for new
stuff.

just as another note, as of GRASS 7 it looks like they will be moving their 
default DB format to SQLITE instead of the traditional DBF format
 
http://grass.gdf-hannover.de/wiki/GRASS_7_ideas_collection#Database
 
it might make sense to have a community effort contribute to this as a whole. 
The positive side is that there is already adoption of an OSGEO product as 
GRASS is moving in this direction. Determine a comon schema that can be shared 
around between projects and voila.
 
Or we could ignore this and then revist this same issue again in the future 
with no movement forward.
 
just thought I'd share.
 
Cheers

All,

Don't know the specifics about the engine being used, but we discussed using 
the Plone storage mechanism, a few times, for spatial data.  Just didn't seem 
like a quick enough payoff to try anything out.  At least not on the surface.

There was a thought that there might be something to start with though.

                David and All,
                
                A nice up-and-coming open Java geodatabase format is H2 + 
                spatial extensions.
                
                The H2 database is by the same guy that wrote that HSQL db. H2 
                has some good properties, most importantly, it's small (1 Mb), 
                works well in embedded mode, and is fast. Adding in spatial 
                data in JTS format, and providing a spatial index, is the 
                basic concept.
                
                Two implementations that I know of are
                
                1. The French research group IRSTV, lead programmer seems to 
                be Erwan Bocher.
                http://geosysin.iict.ch/irstv-trac/wiki/H2spatial/Download
                
                2. GeoTools has a H2 spatial module, written by Justin 
Deoliveira.
                Here's a link to the compiled jars:
                
http://maven.geotools.fr/repository/org/geotools/gt2-h2/2.5-SNAPSHOT/
                
                Both are under active development.
                
                regards,
                -Frank

                        Hey Folks,
                        
                        Just wondering if there is still thought out there from 
the previous

across the 
                        nemesis project "an experimental finite element code.

                        Thought that might be a good place to start that is 
already using 
                        geometry in sqlite.
                        
                        As for software adoptions it looks like GRASS already 
has an 
                              

                SQLITE driver.
                    

                        QGIS looks hopeful. Here is a GRASS/QGIS-SQLITE

A friend of mine is building a website and wants to add a map of
India. He asked me today where he could find some good map data on
India and I had to reply that I have no clue.

I know that this list is not the appropriate venue for this sort of
question, but I am hoping that maybe someone on this list would know
and could point me in the right direction? Cholmes sort of
unconvincingly suggested [EMAIL PROTECTED] Does anyone else
have a thought?

Thanks,
Erik

You could try the freemap.in list -
http://lists.freemap.in/mailman/listinfo/freemap - this is more a
source of high-resolution data for particular cities than an
india-wide effort. e.g. http://mumbai.freemap.in/
There's also an OSGeo-India local chapter, and i bet some overlap
between these lists. 

http://mappinghacks.com/2005/08/22/open-geodata-policy-shift-in-india/
is an old blog entry with a bunch of India-policy links, but not data ;P
I'm sure others will have more concrete suggestions.

Well, it's interesting to hear about use cases there. And the
committee has a remit to run a public geodata registry / repository;
so we ideally *should* be able to offer this kind of answer.

Yeah, my thought was that ideally that list would have a bunch of people 
who are really good at finding GIS data, and when someone asks a 
question like that if it's not already in the repository they would have 
good leads on how to hunt it down, and then be able to easily add it to 
the repository.  But I realize that's not how it's set up now, which was 
why my answer was unconvincing.

Recently when i run across unusual sets of particularly boundary and
other vector data, I've been noting them down in the CKAN index - 
http:/www.ckan.net/ - at least this provides a way of publically
noting name, url, keywords, that is guaranteed to stay around awhile. 
It has no spatial properties or query but is a place to start. 
http://www.ckan.net/tag/read/geodata

I *have* been working on a CKAN-inspired spatial metadata/search
project for a little while and would love to test out an open source
release on OSGeo's systems but i don't want to talk about it too much yet

Of course there's GeoNetwork, OSGeo's own "metadata catalog" system, I see
they have a new release candidate due out very soon. It raises the bar
somewhat, offering support for OGC and ISO standards which may be
overkill for simple web mapping use cases. The more the merrier
though, and there are plenty of systems resources to run all this stuff
on, what's missing is peoples' time to setup and contribute to a
repository effort that'll make future questions easier to answer
without repeating ourselves :)

cheers,


jo
