In search of free orthophotos for my AeroflyFs2 Jena mini scenery I looked up the "Landsvermessungsamt Thüringen" being the responsible state entity for such photos. Besides commercial offers, they seem to provide "OpenData" here
https://onlineshop.thueringen.de/th9/tlvermgeo/geoshop/airortho/digiortho/index.aspx#
(In German only, but you may get it.) After following the link and zooming in I choose the layer icon (lower right, DOP colored) and got a selection for download. The download offers a zip file containing three files
.meta, .tfw, .tif (the actual image). I looked up the tif and (seen as a non-expert) it would provide a perfect ground layout for my purpose.
Two questions for the experts:
1. Where's the hook?
2. Can this format be used for Geoconvert (supposedly not) or converted to something usable with Geoconvert?
I don't think so much on my own scenery only but on a larger plot to get something usable for Germany in general (suppposing the other Landesvermessungsämter providing similar data).
Kind regards, Michael
