have played with rasters for a few years. Most of what we are doing is map
algebra so taking one - many raster(s) and executing some function and
making the final raster available for viewing with mapserver. cellwise
work is the simplest so I use simple C programs to do that. neighbourhood
works gets a little more fun. I have not done the vector to raster
conversion on the fly, in first round this is exactly what mapserver is
doing. I give a shapefile and it gives me a raster. for a broader
approach the idrisi or grass libraries are where I head. GDAL
support?</FONT></SPAN></DIV>

option is to go to ESRI's ArcGISServer (which I don't want to do, if I don't
have to). Are there any other tools available to do raster analysis
