Hi, This page https://viewer.nationalmap.gov/services/ includes a link under "WCS Services" that lists a number of subdatasets. This command
gdalnfo " https://elevation.nationalmap.gov/arcgis/services/3DEPElevation/ImageServer/WCSServer?request=GetCapabilities&service=WCS " works fine. I have been retrieving elevation data from the first subdataset: SUBDATASET_1_NAME=WCS: https://elevation.nationalmap.gov:443/arcgis/services/3DEPElevation/ImageServer/WCSServer?version=2.0.1&coverage=DEP3Elevation SUBDATASET_1_DESC=DEP3Elevation and most of the time it works but I think I must be doing something wrong since sometimes there are large missing areas. For instance this area (Boston) works just fine: gdal_translate "WCS: https://elevation.nationalmap.gov:443/arcgis/services/3DEPElevation/ImageServer/WCSServer?version=2.0.1&coverage=DEP3Elevation"; test.tif -projwin -71.07 42.36 -71.03 42.33 -projwin_srs EPSG:4326 -tr 100 100 but this command with only a different "projwin" (in Colorado) is about 75% missing: gdal_translate "WCS: https://elevation.nationalmap.gov:443/arcgis/services/3DEPElevation/ImageServer/WCSServer?version=2.0.1&coverage=DEP3Elevation"; test.tif -projwin -107.03 37.28 -107 37.25 -projwin_srs EPSG:4326 -tr 100 100 Can anyone help me understand what I'm doing wrong here and how to fix it? I am using a very recent OSGeo4W featuring GDAL 3.0.4, released 2020/01/28. Thanks very much for your help, carl
