Re: [OSGeo-Discuss] Newbie Question? Any feature for classification?
Thanks a lot daniel I asked them at forum of mapwindow. but they told me mapwindow has no feature like this.

Any feature for classification? Saka, Feel free to browse the MapWindow forums here: www.mapwindow.org/phorum and possibly post your question there. We have a very large .NET open source GIS developer community there who may be able to help. Dan On Mon, Apr 14, 2008 at 4:33 AM, Saka Royban [EMAIL PROTECTED] wrote: Hi all.

RE: [OSGeo-Discuss] Proposal: OSGeo Cartographic Library
GDAL has feature style specification: http://www.gdal.org/ogr/ogr_feature_style.html It has recently gained some new interest. Well, GDAL is close to the FOSS4G community so why not start with this and see where we can go? I think OSGEO even has some capable expertise somewhere in the organization that may have a few thoughts (SMILE). I'm interested in learning more if anyone has some experience. How could this be incorporated into the worflow? Cheers ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss

Dave, In my opinion we would be better off starting with a widely accepted standard like SLD as a basis of a feature styling standard rather than the ideosyncratic OGR feature styling specification. If anything, I'd like to phase out the OGR feature styling in favor of something else more widely supported at some point in the future.

Re: [OSGeo-Discuss] Proposal: OSGeo Cartographic Library
One addition to what Chris points out, to complicate things :-), SVG vector symbols can also be used inside an SLD document (for a Mark). To be even more precise, we are really talking about the Symbology Encoding (SE) spec here. SLD as of version 1.1 only deals with the integration of symbology encoding into WMS. Symbology (and the rules) was taken out of SLD since it is more generic than only WMS. But most current implementations still use SLD 1.0 where all is in one spec. http://www.opengeospatial.org/standards/symbol Best regards, Bart Christopher Schmidt wrote: On Tue, Apr 15, 2008 at 06:53:19PM +0300, Ari Jolma wrote: Frank Warmerdam kirjoitti: In my opinion we would be better off starting with a widely accepted standard like SLD as a basis of a feature styling standard I'm right now looking at SVG.

[OSGeo-Discuss] AAG Boston OSGeo Social Meetup
AAG is happening in Boston this week, and in an effort to make some things happen, I'm planning to have a social meetup this Thursday with anyone who is interested in coming. Time: Thur, Apr 17th, 7:45PM Place: Grendel's Den, Harvard Square, Cambridge Who: Anyone interested in Open Source Geo Why: To get together to chat socially about stuff over some beer and bar food. Directions: Get to Harvard Square. Head south on JFK street past The Garage on your left. You will cross Mt. Auburn St. On the Southwest corner is a small open green space: on the opposite corner from JFK is the entrance to Grendel's, below Upstairs on the Square. I'll be there, hopefully by 7:30, with an eeepc and an OSgeo shirt on.
