Use of SkyDemon in the USA is discouraged and our charting there shouldn't be regarded as comprehensive. The terrain tiles we use are in the SRTM3 format at this stage, though that's undocumented and subject to change. I can't recall where in the Android filesystem we store these, you'd have to dig around yourself. This is all unsupported territory. You might want to look at newly released AW3D30 model by the Japanese space agency (last update was at the begging of 2019): https://www.eorc.jaxa.jp/ALOS/en/aw3d30/index.htm It's absolutely free, with good resolution and it's DSM. Unlike DEM and DTM, Digital Surface Model includes vegetation and man-made structures (which is a good thing for pilots ). Edited 3/3/2020 7:34:09 AM by 177

Btw, it was on the forum before that you don't supply a US Sectional chart style. But how deep is this coded into SD? Is there any change one could build his own style or could i help you in providing data and work? About the comprehensiveness of the chart data, I compared SD's map with a current Atlanta sectional for the souther Tennessee area and so far I couldn't find anything missing. If I find errors or missing data, do you like to get the custom data files for that?‌‌ Florian‌‌‌

Group: Forum Members Posts: 17, Visits: 16	Hi, I am using Skydemon for a couple of years now and am really happy with it. Because I will go to the States for a pilots vacation soon, I tried to download high resolution terrain for the Appalachian region but it seems that the SD server is not providing data there. PC:‌ Since ‌‌it looks like the terrain files for Europe are identical with the SRTM file from NASA I wonder if I could just download from them and past it into my Skydemon folder along the European files. Or might this cause any problems because SD has reworked their charts in any special way? Android:‌ Also I wonder where SD stores it's terrain data on mobile devices. I activated the automatic downloading function but while moving the map around in northern Germany no files seem to be downloaded. How can I check is the files were indeed loaded or did I do something wrong in the first place? So far, everyone a good slide into the new year! Florian‌‌‌‌
