thanks I will add those dimensions to the list.
I don't have the H and T maps for all these maps either, and even if i did, i wouldn't be able to check the dimensions.
Is there a way i can check the pixel sizes with out having to convert or open the file. I've checked properties but there is nothing indicating size there.
If conversion distorts the sizes then i'll have the wrong dimensions again.

If it's any consolation, I could not open the F map either, no matter which viewer or graphics program that I used. The compression type or whatever it is, doesn't seem to be supported by any program I have. However, by extracting the other components of the Crimea map, the T / H and ed_m02 maps, I saw that these maps were NOT compressed. They opened easily in all viewers and graphic editors.

And since all these maps, and the F map have the exact same dimensions, if all you need is the dimension, then any will suffice.

And you can always take the T map, make a copy, convert to rgb 16million colors, and select each gray rgb value and convert to a color that is appropriate for the F map (an approximation of the ground texture color). Then you follow kevin's tutorial on how to make an F map (too complicated to explain here) and voila, you'll have an F map, uncompressed and in the correct dimensions.

All this takes about an hour or less to do once you've gone through the tutorial. Say it take double or triple as long the first time, you'll still come out ahead instead of trying again and again a procedure that apparently doesn't work.

Just make a new F map ... and then you can continue with your own procedure ...
