Re: [OSM-dev] WMS API - where to start
Not sure what you mean by designing a WMS API but a search on WMS specification seems a good start. - Chris - On Thu, Apr 15, 2010 at 12:35, bernhard b...@datenkueche.com wrote: hi all I'm working again on my map maplib. http://github.com/robotnic/khtmlib Internet Explorer should work now (exept vector graphics).

[OSM-dev] WMS Overlay Disappears
Hi! I am generating a map using OpenLayers with an OSM base map and a WMS overlay. At the backend I am running GeoServer 1.7.3 with PostGIS. I can view my WMS data fine in the client in GeoServer and in uDig. However when I overlay it on my OpenLayers map it disappears at nearly all the zoom levels. Here is a demo: http://www.britishideas.com/osm When you load this you can see a black dot over southern Arizona. This is my overlay. When you zoom in it disappears. Any ideas what I am doing wrong? thanks, Andy -- Andy PGP Key ID: 0xDC1B5864 ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev
Re: [OSM-dev] WMS Overlay Disappears
This is more suited to the OpenLayers list, but at a guess it's because of an incorrect maxResolution setting on the WMS layer, they default to the Map, or if that's not set, auto-generated not always successfully. Setting up the Map object as shown here should be the first step to getting the overlay to display. http://wiki.openstreetmap.org/wiki/OpenLayers_Simple_Example#Instructions 2009/3/30 Andrew Ayre a...@britishideas.com: Hi!

Re: [OSM-dev] WMS
2008/6/25 Iván Sánchez Ortega [EMAIL PROTECTED]: Hi all, First of all, I want to say that WMS sucks. The 100-page spec sucks, the efficiency sucks. That said, I just committed to SVN a set of hacks I've come to call OSM WMS. Why? Long story short, this will allow me to promote OSM to GIS people. Or, as FakeSteveC would say, Arctards. However, the current implementation has the potential of pounding the API down to its knees (no caching of any kind). In fact, I think it has more bugs than features. So, I'd like to know if you think it would be a good idea to do load balancing between several OSMXAPI servers. This is probably a good idea. Do you have any servers in mind? (Yes, I know the best solution is to set up a local mirror of the database given a planet dump, and get the data from there. I just wanted to make something very simple to set up.) Also, would it be a good idea to call OSMXAPI with the whole earth as a BBOX and try to render the whole coastline? Any ideas on how an OSM WMS would behave on such large requests?

If you would like to test it on an external datasource, and have only SQL request, I'm happy to port the WMS stuff in a new handler for my webserver osm plugin.
