There will be a first version of height + terrain file in the download sections for US_Brandenburg_374549N_862821V_40x40 with focus for the Irvington area.
It's Brandenburg and Irvington area in US, Kentucky. Not Brandenburg in Germany.
The terrain file is the 1,0 version with terrain around Irvington but with not so many buildings. Hopefully, there will be more buildings in the next version.
