I'm composing a map with aerial footage with mapserver and tilecache. I have tiffs with geo information, then I run gdaltindex to create the shapefiles and then I configure the map file with layers like this:
LAYER
NAME "viana"
STATUS default
TILEINDEX "viana.shp"
TILEITEM "location"
TYPE raster
OFFSITE 0 0 0
PROJECTION
"init=epsg:27492"
END
PROCESSING "RESAMPLE=BILINEAR"
PROCESSING "DITHER=YES"
TRANSPARENCY ALPHA
MAXSCALEDENOM 54000
MINSCALEDENOM 423
END
How do I set a default image in mapserver for when I'm have no data for some specific area, like an "Image not available at this zoom"? Like http://12f.p8.sl.pt
default imagebeing provided.
