Help with rasters

[B Tuttle]

Have you tried the following where TILEINDEX is the name of your index
shapefile and TILEITEM is the name of the field in the index shapefile
that contains the location of the raters?

LAYER
  NAME "LayerName"
  STATUS ON
  TILEINDEX "RasterIndex.shp"
  TILEITEM "Location"
  TYPE RASTER
END
