Hi, I'm new to mapserver but fairly experienced with GDAL. I hope that someone can explain where I've gone wrong with setting up WMS.
I followed the instructions here [ https://worldwind.earth/elevation-server.html] almost exactly to set up a WMS server and it sort of works. (I am using MS4W actually, so I didn't install Apache & Mapserver as that page described and of course I made a few other adaptations for Windows.) I downloaded the GEBCO tiles from here [ https://www.gebco.net/data_and_products/gridded_bathymetry_data/] without any problems. What I don't understand is that while the GEBCO GeoTIFF files that I am using have one band that gdalinfo describes as Band 1 Block=512x512 Type=Int16, ColorInterp=Gray when I look at the WMS bands using gdalinfo, I see three byte-sized bands: Band 1 Block=1024x1024 Type=Byte, ColorInterp=Red Band 2 Block=1024x1024 Type=Byte, ColorInterp=Green Band 3 Block=1024x1024 Type=Byte, ColorInterp=Blue I'd really like to get 16-bit integer elevations from my WMS server but I don't know why this didn't just happen or how I mis-configured things to make it not happen. I know these are not complete details, but rather than write a novel for my first post here, I'm hoping someone can suggest where the problem might be or suggest some further documentation to read. Thanks very much, carl
