Ed, Glad to hear you're making good progress. I wasn't clear in describing the proj call. In the GeoTransform, (X0,Y0) is the upper left corner of the source grid in coordinates of the source projection. From the lon/lat grids from your source dataset, you can find the lon/lat of the upper

And that would be what happens when you view a geotiff in a program that isn't made for geotiffs. I got my image, it's reprojected, and rotated a bit so I'm going to look into my numbers, but I think I've got the process down. Just wanted to say thanks again to everyone that offered help. -Ed ___

Steve, that write up was excellent. Thank you for that. You definitely weren't telling me anything I already know. If I could just get a little more help, I think I'm so close. My output file seems to have problems. The resulting image is 25k, but it's just black. Gdalinfo on the resulting geot

Ed, Looking at your gdalwarp call, it seems that you've omitted the projection parameters. Based on your description of the projection, I would expect a gdalwarp call such as the following: gdalwarp -s_srs "+proj=lcc +lat_1=33 +lat_2=45 +lat_0=40 +lon_0=-97 +a=637 +b=637 +x_0=0 +y_0
