No help maybe but here's URLs to the two programs mentioned there at the gtopo30
web page.

I think it just comes down to the change in data format.
See the section 5.0 here in the readme:

| So, is there a way I can convert this 'simple binary raster format' ? With
| Photoshop 5 maybe.
| I have to say that I have never heard of this file format.
|
| If anyone knows if/how it can be converted. I tried to open it as a RAW  file
with
| different options, but all I get is a blurry image.

|
| Thanks
