I'm trying to put some GeoTIFF format raster data with multiple bands
into MapServer WMS and WCS.
My goal is:
- For WMS, use something like "bands=2" in a WMS request to retrieve an
image of a specific band.
- For WCS, use something like "bands=2" or "bands=2,4,7" in a WCS
request to retrieve data of some specific bands.
What I did is:
- In the mapfile for WCS, I added
"wcs_rangeset_axes" "bands"
in the LAYER's METADATA part, so I'm able to use "band=2" or "band=4"
to retrieve only ONE band in each WCS request. But I can't retrieve
multiple bands using something like "bands=2,4,7", the Exception message
looks like:
<ServiceException code="InvalidParameterValue"
locator="bands">msWCSGetCoverage(): WCS server error. Error specifying
"bands" parameter value(s).
I have no idea at all about how to configure WMS mapfile to enable the
bands parameter.
Can anyone help me to solve this issue? Thank you very much.
Sincerely,
Yaxing
