Hi,
WCS users are supposed to read the metadata with DescribeCoverage, for example
https://avoin-visukuva.nls.fi/ortokuvat-ja-korkeusmallit/wcs/v1?service=WCS&version=2.0.1&request=DescribeCoverage&coverageID=ortokuva_vari
The units can be configured in the mapfile with “wcs_band_uom”. I do not know
if it is possible to configure the outputformat to write uom also into the
TIFF. That is something that GDAL should do.

Aihe: [mapserver-users] WCS layer units question...
Hi,
I have a local WCS & WMS server.
I am trying to figure out if I can somehow define the Z units of a terrain
layer I'm serving.
The single band from the individual GeoTIFF files providing the terrain data
looks like this (from gdalinfo):
Band 1 Block=512x512 Type=Float32, ColorInterp=Gray
Description = Layer_1
NoData Value=-999999
Unit Type: m <===================================== units are meters
Metadata:
LAYER_TYPE=athematic
RepresentationType=ATHEMATIC
but when I download a GeoTIFF using a WCS GetCoverage request on this layer,
the GeoTIFF's single band just looks like this:
Band 1 Block=571x3 Type=Float32, ColorInterp=Gray
without "Unit Type."
I also tried using
UNITS Meters
in my LAYER definition in my map file (copying an example I found among the
case studies on the web site) but it didn't seem to have any effect.
Is there some way to define and retrieve the Z units for a WCS server?
Thanks very much.
carl
