[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

[mapserver-users] Display performance

2010-09-02 Thread Chris Jackson
Hi I wondered if anyone knew if displaying a 50,000 polygon dataset would be significantly faster if called from a database rather than a spatially indexed shapefile, or is it a similar overhead for both. Thanks Chris ___ mapserver-users mailing list

Jukka Thank you for the code I will give it a go. I guess I will dust off the field calculator in ArcMap and see if that improves things somewhat, I guess that is a similar overhead when classifying a raster by pixel value (not sure how to fix that). So if I understand you right then I would
