I am messing around with some opendap weather data and tinkering with gdal. Does anyone have any test data/links I can use? I used gdalinfo to look at this data:
http://nomads.ncdc.noaa.gov/dods/NCEP_NAM/subsets/nam_218_winds.dds using: kyle@ubuntu:~/Desktop$ gdalinfo http://nomads.ncdc.noaa.gov/dods/NCEP_NAM/subsets/nam_218_winds?ugrd10m[0][y][x] Driver: DODS/DAP 3.x servers Files: none associated Size is 1038, 500 Coordinate System is `' Origin = (-153.050000000000011,11.949999999999999) Pixel Size = (0.100000000000000,0.100000000000000) Corner Coordinates: Upper Left (-153.0500000, 11.9500000) Lower Left (-153.0500000, 61.9500000) Upper Right ( -49.2500000, 11.9500000) Lower Right ( -49.2500000, 61.9500000) Center (-101.1500000, 36.9500000) Band 1 Block=512x128 Type=Float32, ColorInterp=Undefined NoData Value=9.999e+20 Overviews: 519x250, 259x125, 129x62 and I noticed the origin y values are inverted. The image 'shows' up in the right place because the y pixel size is positive, but adfGeoTransform[3] is wrong. I am also not getting any data back (all nodata) but I am not sure if that is me, or the provider. I am looking for a link to test the dods driver and see if this is always the case, or if the data served by nomads is an exception. Thanks. kss
