===== Concepts =====

The “Trees Analysis” extension automatically detects trees based on a point cloud and a set of user-defined parameters. 

The extension uses the concepts and generic workflow of [[dev:desktop_ext:generic|]].

A tree feature is expected to have a trunk and a crown. Trunk is identified as a pole-like feature, and after the crown is detected on top. Different crown diameter calculations can be selected in parameters.
