[MapServer-users] "Emergency" map server on Raspberry Pi - raster/PNG source in folder structure

[Sven Schroeter]

Hi Stefan,

I don't know if I understood you correctly, but I think the solution for 
you would be an image catalog, right?
Then you would have only one layer for the UTM maps.
In the mapfile it would look like this, in the .dbf in the column 
"location" would be the paths to the png data.

LAYER
     NAME "utm_data"
     STATUS ON
     MAXSCALE 8000
     TILEINDEX "filesindex_png.shp"
     TILEITEM "location"
     TYPE RASTER
     PROCESSING "Resample=average"
     CLASS
     name "utm_data"
     END
END


Greetings Sven
