Hello, I'm fairly new to reprojection and my experience with gdal is limited, so I'll do my best to keep up. I have tried searching through a number of messages without finding anything quite like my problem.
I've been completely unsuccessful trying to reproject a netcdf file for some time now and I'm becoming fairly desperate for some help. I'm going for changing "Lambert Conformal with a perfect sphere geoid with earth radius=6370km centered at 40N, 97W with standard latitudes at 33N, 45N to geographic lat, long (flat) projection." First, a little gdal info on one particular subdataset for the netcdf file: Warning 1: No UNIDATA NC_GLOBAL:Conventions attribute Driver: netCDF/Network Common Data Format Size is 148, 112 Coordinate System is `' ... ad then coordinates, cdate, ctime, xcent, ycent, etc. etc. I was wondering if NC_Global or the coordinate system being `' might cause a problem. and then, running the command (going to mercator just to get a successful reprojection, I'll deal with lat/lon later): gdalwarp -s_srs "+proj=lcc" -t_srs "+proj=merc" NETCDF:"test_0910.nc":PM25 NETCDF:"test_out.nc":PM25 gives me: Warning 1: No UNIDATA NC_GLOBAL:Conventions attribute ERROR 1: Unable to compute a transformation between pixel/line and georeferenced coordinates for NETCDF:test_0910.nc:PM25. There is no affine transformation and no GCPs. I'm fairly stuck. If anyone has any ideas at all, I'd really appreciate it.
