What I want to do or know
I would like to know if it is possible to get a 3D map (orthomosaic) from using the balloon mapping method; like what you would get if you use a UAV/Drone (eBee, DJI Inspire). Or does the balloon mapping only create a flat 2D map without data on the terrain/topography?
Background story
I work with an NGO, looking to map out villages of rural settlements in my country as a base for village development.
Juan Pablo Torrente has made several maps out of balloon and kite mapping https://sketchfab.com/bajaltura.com They are amazing 3D maps, like this one from Las Médulas in Spain https://sketchfab.com/models/88bb7c08a8104650ae3f3ed3b026e882 He made for us this 3D map of a square in Barcelona.
A commercial tool like PhotoScan can be used. It is a good opportunity to ask if people are using any open source software for post processing 2D images into 3D.
The software needs a good amount of photos from different angles and positions to be able to generate the 3D object out of all the 2D images.
