Hi Folks, I'm trying to do something relatively simple, but I haven't been able to find any examples of others doing it before me. Just thought I'd askhere before going off and writing the code myself.What I want to do is take a DEM stored in the ESRI ASCII Raster format and convert it to a netcdf file. My ascii raster has the standard header format like so: ncols 5001 nrows 4001 xllcorner -125 yllcorner 34 cellsize 0.001 NODATA_value -9999 Anybody got some code to do this? :-) If not, no biggee, just thought I'd ask.
The best way to do this would be to write an IO Service Provider (IOSP) layer that would read in the file and create the netCDF object. I'm not sure if there is any documentation on this, but there are some other examples that you could probably follow. There is code in VisAD to read in the ASCII Arc Grid format into VisAD Data objects and it could be adapted to use for this task. The source code is available at: ftp://ftp.ssec.wisc.edu/pub/visad/visad_src-2.0.jar in the visad.data.gis.AsciiArcGrid reader. It does not handle any associated .prj files.
