Hello All,
I have been trying to read a custom GDAL raster format via MapServer.
(Unfortunately, I'm unable to share the file itself here, as it is a
proprietary format). MapServer is unable to read the raster and display it.
However, GDAL is able to read (gdalinfo, etc), translate (gdal_translate),
transform (gdalwarp) the raster. Any ideas how to solve this? MapServer is
compiled with GDAL support and everything looks OK. The "gdalinfo --formats "
command shows the format is supported.
Here are the errors in my log:
msDrawMap(): rendering using outputformat named png (AGG/PNG).
msDrawMap(): WMS/WFS set-up and query, 0.000s
msDrawRasterLayerLow(testLayer): entering.
msDrawRasterLayerLow(): Unable to access file. Corrupt, empty or missing file
'/path/to/myfile.ext' for layer 'testLayer'.
Image handling error. Failed to draw layer named 'testLayer'.
msFreeMap(): freeing map at 0xf8b8f0.
And here's the MapServer error included in the image or shown on the command
prompt (when ran using mapserv command):
msDrawMap(): Image handling error. Failed to draw layer named 'testLayer'.
msDrawRasterLayerLow(): Unable to access file. Corrupt, empty or missing file
'/path/to/myfile.ext' for layer 'testLayer'.
GDAL: GDALDeregister_GTiff() called.
Here's how my layer definition looks like:
LAYER
NAME "testLayer"
TYPE RASTER
DATA "/path/to/myfile.ext" # <<-- Tested with realtive path from
shapepath and also direct path, as in this case.
STATUS ON
END
Thank you for your helpful pointers.
Regards,
Shri.
