@Aut @WiredForFlight I have a "nicegui" (python) based UAS operator station with moving map (open-street-map). Long ago I had a VRF chart layer working, but that source went away and I've never gotten around to tracking down a new source. For me I'm assuming a web connection (although the nicegui script runs local so you can run offline.) For another part of the project I've been pulling in bing satellite tiles and draping them over SRTM terrain for a fairly convincing 3d world view. Kinda like google earth from 15 years ago before they added 3d objects. I'm using a quad-tree LOD scheme and downloading data JIT and building the 3d tiles ... using python and panda3d. I think developing for tablets/phones is probably an entirely different world though. I'm probably too old school to learn how to do that lol. I'm happy running my python scripts on my linux laptop. :-) One of these days I wanted to work on a 3d flight visualizer with paths and stuff, but there's never enough time in the world and work and life has been kicking my butt for the past few months. https://youtu.be/WR6JeLOauIY https://youtu.be/d6G-cHO-uTU
