[mapserver-users] Feature select performance

2010-08-24 Thread Chris Jackson
Hi all I have rigged up a webGIS app (P.Mapper framework) where one of the underlying datasets is a model grid (many thousand cells) in a shapefile. The data displays nice and quick when just viewing, but if I allow the user to select say 5000 cells it is very (extremely) slow to redraw with the

For reference sake: The issue is also present when using Bing maps as overlay. I also recompiled mapserver against agg 2.5 and gd-2.0.36RC1, but no change unfortunately. As stated in my previous mail, I may have to look for alternatives as the tilecache will probably not be an option for us.

Tilecache probably is not what you want if you have very dynamic tiles. Or at least a tile cache that is persistent. Your problem is with tile edge artifacts. It might be possible to draw on a slightly larger image than the tile, then cut the tile out of it to avoid some of those, but there

Hi Wim, If your data is that dynamic then there is not much advantage in using tilecache. Perhaps there is not much advantage in making tiled requests either. Applications asking for 256x256 pixel sized tiles from on-demand bases are generating rather a lot of load for Mapserver. There is an

Re: [mapserver-users] Feature select performance

2010-08-24 Thread Chris Jackson
Steve The selection of layer data is done by a bounding box, though querying by parameter values is just as slow. The mapfile is directly calling up the shapefile (I had just followed the P.Mapper examples of displaying/querying shapefiles directly). So probably the answers to those questions

My understanding of spatial reference systems(SRS) is that the units of the utilized by the SRS are inherently part of the definition. When data is projected to a particular SRS, the units are set by that SRS. It sounds like you are looking for some sort of cylindrical based SRS Maybe Miller

Thanks for the suggestions.  I am able to reproject my maps with mapserver.  I found out what projection my maps started in by reprojecting in QGIS, it filled in the starting projection.  Either it calculated what that projection was, or it was the default.  Then, wherever my site modified

Yep, it can be done. I'm afraid a how to on your specific problem is well beyond the scope of an e-mail list response, but if you take the time to learn MapServer you'll find you can generate the images you want to embed in your mailings. Based on your website it seems like doing so would be core
