I am looking for some recent tutes on rendering ERDAS .img files. A bit of the background:
I inherited these data as an ArcMap .mdb dataset which has metadata.xml, a few other sundry files, and inside a directory with .idb extension, many more folders, each containing a .img file, and a corresponding .rrd and .xml file. A simple layer definition like so allows me to get the tiles displaying in the browser (via OpenLayers) -- LAYER NAME "lyr" TYPE RASTER DATA "foo.img" PROCESSING "SCALE=AUTO" STATUS ON OFFSITE 0 0 0 END But, the tiles don't make for a continuous image. I can see the tile boundaries. Besides correcting that, I would also like to be able to apply different color ramps, and, finally, I would like to be able to query either single pixel values (click on the map and get the underlying value), or some kind of stats on pixels in an area. Would appreciate any tutorials/write-ups if anyone has done this. Many thanks, -- Puneet Kishor_______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
