Thank you for sharing your pictures and information with us on your big project "Let's do Niederbayern".
While looking at your (especially) last screenshots, a couple of questions have come up with me. I would be glad if you could answer that.
-What source data do you use, Google or Bing?
-What level do you use in "FSET" or "AeroScenery" when downloading the image data, 0.5 m / Px, 1 m / Pix?
-What level for AFS2, Level 9, 10, 11 .... 15?
-Do you edit your Images (PhotoShop) before using GeoConvert?
-Did you rework the water "Bodensee / Lake Constance" (to see on your shot: Friedrichshafen?
-How do you design the transition at the border of Germany and the IPACS Switzerland?
-What is the name of the wonderfully modeled airfield on the screenshots of your posts # 23 and # 27? And is the airfield anywhere to buy?
Thanks again. It is unimaginable how much work and time are involved in such a project. I wish you much pleasure in the further design of your project.
