Hello Mike.

I just bought Global Mapper (14.2.6) in my new company. Just great!

But unfotunately the creation of roughness lines/areas doesn't work really smooth.
I used the download source implemented in GM and the standart "CORINNE Land Cover Summer" option.
(The location is in Germany, 40 km North-East of Hamburg)

The result has a lot of uncombined areas which also doesn't connecte in the export dialog or when I trie to select everything whith the digitizer tool and use "Combine area features".
Doing so, an error appears:

"Some areas don't intersect from the combination of the areas
Polygon join failed with an internal error. Join will not occur.
Coordinates of first point in areas that failed to join:
(xxxxxxxx)"

Input CORINE data

Input Roughness GM.JPG


Result

Result Roughness GM.JPG


Do you have any suggestions what to do to create an export without these grid-looking like areas?


Kind regards,
Hendrik
