Where does it come from and what kind of terrain model is used in the app (DSM or DEM/DTM)?

Please, consider using a newly released AW3D30 model from the Japanese space agency.
It's free (requires registration):

AFAIK, it's the most recent topographic data publicly available (the latest update comes from January 2021) and it uses a DSM format (e.g., includes vegetation and man-made structures, which is a good thing for pilots). I know first and foremost it's a VFR app, but having more information is better than not enough (when you unintentionally flies into IMC, to make sure you don't smash into anything).

Actually I believe in a navigation app it is best to have a terrain model plus obstacle model, which added together provide the best information. Inside the software we need to know the difference between terrain and stuff that's on top of the terrain, such as a city with many high buildings.

If you have some specific real-world examples where you think a unified model would be of more help to the pilot, it would be good to hear them.

Where did I said that DTM is better than DSM? Smile DSM = surface + objects on it.
Anyway, I still looking forward for the AW3D30 implementation, since it's the most recent and accurate model.

It's me that is suggesting DTM is better than DSM for SkyDemon. I was inviting you to suggest why you disagree.
