How can I query/identify the pixel/cell value of a raster at the location of mouse click? I've searched online and have found vague older references to a pmapper_demo_dev.map and a "corine" layer (which apparently doesn't exist anymore) that demonstrates how to use metadata tags for use with rasters to query/identify. I think I've figured out the METADATA tags that I should use, But nothing I've tried yet returns the pixel value of the raster. Mapserver renders this raster layer without any problem. How do I identify/query the pixel cell value?
I'm using p.mapper 4.1.1 and php_mapscript 5.6. The layer snippet from my mapfile is below. Many thanks.
