[OSM-dev] Some statistics for file-format -development
Hello everyone, during the development of my osmbin file-format I ahev gathered some statistics using an extract of the city of hamburg (a larger extract of all of the state of baden-wuertemberg is computing right now). http://wiki.openstreetmap.org/wiki/User:MarcusWolschon/osmbin_draft#statistics http://spreadsheets.google.com/pub?key=p5alGmffVt6gMsh_x2iXzew They may be usefull for others doing similar tasks. It shows the history of: * how many nodes/ways have now many tags * how many tag-values have each length (for ways and nodes) * how many ways have how many nodes referenced * how many nodes have how many ways referencing them * ... I made the linked spreadshet to find the optimum number of slots for each of these in my fixed-record-length format. PS: I could use some help with specifying and implementing the 2D-index for nodes(location) and ways(bounding-box). ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev
Re: [OSM-dev] Uptime problems of xapi.openstreetmap.org?
Stefan It takes some time to do a complete database rebuild. On bearstech this was hampered by an unexpected reboot of the VM. Meanwhile xapi.openstreetmap.org is behaving oddly. I'm beginning to belive its a hardware problem (memory perhaps), but I'm still trying to nail down the exact issue.

Re: [OSM-dev] OSMXAPI to be ported? (Was Re: Lean and mean Tile- and XML-API-Server)
Thanks, Frederik, for laying out the requirements. I'm actually after a reliable OSM read-only mirror which offers OSM api, OSMXAPI and Tiling services as described in the Lean and mean Tile- and XML-API-Server thread. Given many business cases, the data freshness can be as good as it gets, beginning with weekly/daily replication. Stefan 2008/11/21 Frederik Ramm [EMAIL PROTECTED]: Hi, Stefan Keller wrote: So it seems that the OSMXAPI is the candidate which really needs to be ported? Instead of porting something that exists, why don't you define your needs and then simply write something that serves those needs? OSMXAPI, for example, has a number of special features, e.g. keeping track of a list of users having touched an object or locking certain tags so that only the person having created it can modify it, which are cool to have but might be unnecessary baggage for the application you have in mind. It is also important to know whether you're aiming at some sort of live replication (using minute diffs and applying them quickly) or whether you are aiming at loading daily diffs; this might also cause you to make different design decisions. Systems that can work with minute diffs tend to spend more time on initial setup, whereas a system that just loads the planet file and is thereafter unable to process minute diffs can load the planet much faster. Another factor is whether or not you need to by XML compatible with the API; if it is sufficient for your application to hand out, say, WKT geometries then you might go down a different route than if you need to hand out the exact data objects. And so on. If you are aiming at a read/write environment then it will be hard to surpass the current API performance. If you intend to do readonly then there's a number of shortcuts you can take.

I suppose you can put that URL into JOSM and download

I tried using JOM version 1087 and the most recent

Actually it does not delete it, but becomes invisible.

well, you can't orthogonalize those as the function tries to
orthogonalize _all_ edges. that does not work with such a shape as only
shapes with an even number of edges can be truely orthogonalized!
I think we need another check before orthogonalizing. how about that:
// Check if way has an even number of edges
if (((way.nodes.size() - 1) % 2) == 1) {
JOptionPane.showMessageDialog(Main.parent, tr(Please select a way

Some improvement. I downloaded the new ewmsplugin using update in JOSM I downloaded the webkit on the same address as before. I get image, but vertically compressed to approx 1/3 of the screen. All data seems to be there. Higher and lower parts of screen remain white. Automatic download functions when scrolling left-right.

Re: [josm-dev] [PATCH] - OrthogonalizeAction
I understood, and it was not meant to be orthogonalized.
Just playing and testing.
The message (for now):
Why not change the negative into positive :
Please add another corner to orthogonalize this shape / polygon
Some suggestions:
Create the same function for 30, 45, 60, 120, 150, 210, 240, 270
degrees AND 90 degrees mixed in one shape.
(gets tricky I think)
May be that could work on my star building.
Would be nice however if those corners that ARE within
for example 85 and 95 degrees were orthogonalized.
As well as corners close to +/- 5 degrees could
be straightened.
Even better if the remaining angles could be symmetrized.
I am not sure however, if that works on all shapes .
A further improvement could be to accept all shapes
that are -selected- instead of just single closed ways. many many
roads are essentially build rectangular, and
in the maps only close approximations.
I imagine 4 roads selected . As your calculation
happens only on the nodes (isn't it?) it must be possible.
Thanks for the great work. This literally improved
my building mapping with a factor 2 at least, at the same
time creating much better results.

[OSM-dev] What's the attitude on embedding [EMAIL PROTECTED] or informationfreeway slippy maps on own site?
Hello everyone, I have to admit I haven't done much work on Freemap lately - other commitments being a big factor but an equally important factor being that my server cannot cope well with an OSM database covering most of England. So I was considering an alternative approach, in which Freemap no longer focuses on providing custom OSM maps for walkers, but rather uses the standard OSM maps (probably [EMAIL PROTECTED]/osmarender, as they distinguish between tracks with private and public access which is vital for walkers) and focuses instead on providing a separate and more lightweight data layer which allows walkers to report problems with paths, contribute directions in difficult places, photos, etc. However this would obviously mean Freemap embedding [EMAIL PROTECTED] or informationfreeway.org maps in its own site. How acceptable would this be seen to be? Thanks, Nick ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev

So I was considering an alternative approach, in which Freemap no longer focuses on providing custom OSM maps for walkers, but rather uses the standard OSM maps (probably [EMAIL PROTECTED]/osmarender, as they distinguish between tracks with private and public access which is vital for walkers) and focuses instead on providing a separate and more lightweight data layer which allows walkers to report problems with paths, contribute directions in difficult places, photos, etc. However this would obviously mean Freemap embedding [EMAIL PROTECTED] or informationfreeway.org maps in its own site. How acceptable would this be seen to be? Thanks, Nick Perfectly fine, providing the standard OSM attribution. In fact, the OpenLayers definition[0] was produced so people could do this easily!

Re: [josm-dev] Cant point to JOSM build dir
I just tried the version in the OSM svn and I cannot reproduce your problem. Ok, I get some deprecation warnings, which should of caurse be cleaned up but it works. And I have to admit, that I have adapted your build.xml to the scheme used by other plugins. BTW: when using the DirectUpload and putting the character ',' into the tags field it ends up with a Bad Request error. It should better check for comma characters before trying to upload. And, I would prefer it, when the filename which is stored in the GPXLayer (if there is one) instead of a temporary one.

Many corporate boys always go to battle with the stupid argument you made. Your general statement only points out laziness of developers, doing things in shorter time resulting (usually) in suboptimal solutions. Since we are a group of people that not get paid and therefore need to produce better work in order to use our facilities more optimal it is to defend to always try to improve the work, because the userbase grows and the amount of hardware is limited.

The amount of people here that feel responsible for each others code is very low. If you look at the tools available for processing OSM data it is also easy to see that some are superseded a long time ago and others get bitrot by updated APIs. In my perspective; if everything is unittested and the limitations are known, they don't break if they are untouched.
