As simple as that!

Many thanks.

Is there a way to get a list of georeferenced maps that are included in a group?

Thanks, Andrew. I'd done a forum search, but I didn't see any other references to this problem - and I totally missed the upgrade... Will check it out later.

Edit: Problem solved, many thanks.

I seem to have a problem in georeferencing google earth images. I followed the steps in the "Tutorial 2: Google Earth™ and TransDEM" exactly. After getting the first few images georeferenced sucessfully, now it no longer works. When I import the image into TransDEM,

This looks very useful, especially as it is designed for purposes such as flood defenses, it (the DTM version ...

And it's not working...
Will send copies of the relevant files to you.

Any ideas?
