    Hi, I'm working with satellite data in hdf format which I'd like to bring into GIS. I've read my hdf file into IDL but can't figure out how to convert/export it to something GIS can read. I'm pretty sure I can handle an ascii file in GIS, but can't figure out how to get my data to ascii. I'm a total newbie with IDL, so any help to get me over this hump would be much appreciated. PS- I just checked my GIS and looks like a binary floating point data file will work also. Thanks! Pam

    Hi Brandon, Thanks for your reply! I need the header information and the values for the variable I am interested in, which is sea surface temperature. Here's a sample from an ascii file that I was able to bring into GIS showing the header and a portion of one row of data: ncols 321 nrows 401 xllcenter -125.0 yllcenter 35.0 cellsize 0.0125 nodata_value -9999999 12.8854 12.8746 12.9269 12.8426 12.8512 12.7466 12.7298 12.6947 12.5244 12.545 12.6332 12.6695 12.7041 12.9039 12.9081 12.9117 12.9761 13.0778 13.0807 13.0381 13.0196 13.0583 13.0069 12.9625 12.986 13.0291 Pam
