Hi, I wonder where BBOX (-2.5,-2.5,2.5,2.5) comes. If Mapserver is generating it automatically then it feels like a bug.
Your request does not contain BBOX at all and it is OK because it has TIME, and WCS 1.0.0 standard says "One of BBOX or TIME is required". CRS is required but because there is no BBOX it should not have any effect on the result. Standard says here "GetCoverage requests must use this parameter to specify the coordinate reference system in which the request domain constraints are expressed (BBOX). The values of this re-quest parameter must be one of those defined in a requestResponseCRSs or requestCRSs element under the requested coverage." Thus you are allowed to use any CRS that your service supports and the result should be correct and identical. And your CRS list seems to be this: "wcs_srs" "EPSG:4326 EPSG:900913 EPSG:3857 EPSG:32615 EPSG:32616 EPSG:32617" Do you get the same error also if you make the request with for example &CRC=900913? I guess that your system is sometimes generating requests with EPSG:4326 BBOX and therefore you just that as a compulsory dummy CRS parameter with your bare TIME requests and therefore using the native EPSG:32626 is not a good workaround. -Jukka Rahkonen- Lähettäjä: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] Puolesta Peter Freimuth Lähetetty: 29. tammikuuta 2014 9:17 Vastaanottaja: mapserver-users@lists.osgeo.org Aihe: [mapserver-users] wcs 1.0.0 bbox problem Hi, executing the following request https://devcloud.blackbridge.com/wcs/PlenumsoftDemo?SERVICE=WCS&VERSION=1.0.0&REQUEST=GetCoverage&COVERAGE=testdata_raw&FORMAT=GEOTIFF_INT16&RESX=5&RESY=5&RESPONSE_CRS=EPSG:32616&CRS=EPSG:4326&TIME=2012-04-05 results in <?xml version='1.0' encoding="ISO-8859-1" ?> xmlns="http://www.opengis.net/ogc"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.opengis.net/ogc http://schemas.opengeospatial.net/wcs/1.0.0/OGC-exception.xsd";> msWCSGetCoverage(): WCS server error.

END If i use CRS=EPSG:32616 which is the epsg code of the layer itself, everything works fine. I would expect that mapserver would reproject the wcs_extent or layer_extent or map_extent to the given CRS and use that BBOX by default. related to: https://github.com/mapserver/mapserver/issues/4853 -- Peter Freimuth
