[UMN_MAPSERVER-USERS] using attributes in the VAT table of a GRID instead of Value

[Monica Petri]

Hello listers,

I want to map a grid not using its Value [pixel]

but using an attribute within the VAT table itself.

 

I tried using the same coding in the *.map file, but it doesn't work.

Any ideas why or any workaround? 

 

Thanks in advance 

Monica
