    Objectives:

Take OpenDroneMap from simple toolchain to an online processing tool + open aerial dataset. This would be distinct from and complementary to OpenAerialMap:

Explicitly engage and provide a platform for drone enthusiasts to contribute imagery in return for processing services.
Address and serve:


Aerial imagery
Point clouds
Surface models
Terrain models


Additionally, as part of a virtuous circle, digitizing to OSM from this aerial imagery would refine the surface models and thus the final aerial imagery


Digitizing OSM on this dataset would result in 3D photogrammetric breaklines which would in turn refine the quality of surface and terrain models and aerial imagery.

Outputs / Data products:


Aerial basemap
(ultimately with filter for time / season?)
Point cloud (see e.g. http://plas.io)
Digital surface model (similar to Open Terrain)
Digital elevation model (in conjunction with Open Terrain)
