[Gdal-dev] xml file for accessing to a wcs server

[salwa]

Hi Frank,

this is my WCS service description file:

-------------------------------------------------

<WCS_GDAL>
  <ServiceURL>http://localhost:81/cgi-bin/mapserv.exe?map=NDVI.map&amp;SERVICE=WCS&amp;CRS=EPSG:26191&amp;</ServiceURL>
  <CoverageName>NDVI</CoverageName>
  <supportedCRSs>EPSG:26191</supportedCRSs>
  <PreferredFormat>gtiff</PreferredFormat>
  <GetCoverageExtra>&amp;BBOX=279728,114867,296168,125307&amp;time=2002-11-07</GetCoverageExtra>
  <Version>1.0.0</Version>
  <BlockXSize>551</BlockXSize>
  <BlockYSize>351</BlockYSize>
  <BandCount>1</BandCount>
  <BandIdentifier>bands</BandIdentifier>
  <BandType>Byte</BandType>
</WCS_GDAL>
-----------------------------------------------

and the Mapfile :

Salwa,

It would be helpful if you could provide the WCS service
description file, assuming the WCS service is public.
