Hi, Cora told about his problems with WCS and 8-bit input images in another thread that was originally dealing with 16-bit RBG images. That thread was http://osgeo-org.1560.x6.nabble.com/geotiff-48bit-with-mapserver-7-wms-td5316916.html
I had a look at the test image from https://www.bscw.nrw.de/pub/bscw.cgi/7035084 The image appears to be a paletted one: gdalinfo original_image.tif Driver: GTiff/GeoTIFF Files: original_image.tif Size is 3200, 3200 Coordinate System is `' Metadata: TIFFTAG_RESOLUTIONUNIT=2 (pixels/inch) TIFFTAG_SOFTWARE=IrfanView TIFFTAG_XRESOLUTION=508 TIFFTAG_YRESOLUTION=508 Image Structure Metadata: COMPRESSION=PACKBITS INTERLEAVE=BAND Corner Coordinates: Upper Left ( 0.0, 0.0) Lower Left ( 0.0, 3200.0) Upper Right ( 3200.0, 0.0) Lower Right ( 3200.0, 3200.0) Center ( 1600.0, 1600.0) Band 1 Block=3200x2 Type=Byte, ColorInterp=Palette Color Table (RGB with 256 entries) ... I do not know how to handle paletted input rasters with Mapserver properly. What I have done is to convert the paletted images first into RGB images with http://www.gdal.org/pct2rgb.html. In my case the source images were also using different palettes which was another reason for using pct2rgb. Cora, I suggest you to have a try with converting your 8-bit single band paletted maps into 8-bit RGB images with pct2rgb.py. -Jukka Rahkonen- _______________________________________________ mapserver-users mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/mapserver-users
