ArcInfo Ascii Grid

[Christopher Condit]

I gave up on using Oracle Spatial to generate raster images from SDO
points on the fly.  Instead - I pull the proper information from the
database into an ArcInfo ASCII Grid file.  This much is working fine -
however I'm running into some issues when attempting to display the .txt
file through MapServer:

*) How to use the CLASS in the layer to change the raster
classification.  Right now it just ranges from black to gray.  The
information is there but almost impossible to see.  How do I change this
to range from red to blue - and be stratified automatically?

*) Does the NODATA_Value in the ASCII Grid file mess up the
classification scheme?

 

Thanks for your time,

 

Chris
