I guess you mean a WCS, and I think it is possible, just put the xml file in SourceFilename under VRTRasterBand. Very quick sample, create a test.xml file like this: <WCS_GDAL> <ServiceURL>http://nsidc.org/cgi-bin/atlas_south?</ServiceURL> <CoverageName>antarctica_satellite_image</CoverageName> </WCS_GDAL> Now if you export this datasource to a vrt: $ gdal_translate -of vrt test.xml test.vrt this is the output test.vrt file: <VRTDataset rasterXSize="48333" rasterYSize="48333"> <SRS>PROJCS["WGS 84 / Antarctic Polar Stereographic",GEOGCS["WGS 84",DATUM["WGS_1984",SPHEROID["WGS 84",6378137,298.257223563,AUTHORITY["EPSG","7030"]],AUTHORITY["EPSG","6326"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.0174532925199433,AUTHORITY["EPSG","9122"]],AUTHORITY["EPSG","4326"]],PROJECTION["Polar_Stereographic"],PARAMETER["latitude_of_origin",-71],PARAMETER["central_meridian",0],PARAMETER["scale_factor",1],PARAMETER["false_easting",0],PARAMETER["false_northing",0],UNIT["metre",1,AUTHORITY["EPSG","9001"]],AXIS["Easting",EAST],AXIS["Northing",NORTH],AUTHORITY["EPSG","3031"]]</SRS> <GeoTransform> -3.1745125000000000e+06, 1.2500000000000000e+02, 0.0000000000000000e+00, 2.8160125000000000e+06, 0.0000000000000000e+00, -1.2500000000000000e+02</GeoTransform> <Metadata /> <VRTRasterBand dataType="Int16" band="1"> <Metadata /> <SimpleSource> <SourceFilename relativeToVRT="1">wcs2.xml</SourceFilename> <SourceBand>1</SourceBand> <SourceProperties RasterXSize="48333" RasterYSize="48333" DataType="Int16" BlockXSize="1024" BlockYSize="512" /> <SrcRect xOff="0" yOff="0" xSize="48333" ySize="48333" /> <DstRect xOff="0" yOff="0" xSize="48333" ySize="48333" /> </SimpleSource> </VRTRasterBand> </VRTDataset> p -- Paolo Corti Geospatial software developer web: http://www.paolocorti.net twitter: @capooti skype: capooti _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
