Ecosynth: 3D Tools for Ecology


3D point cloud of a forest on the UMBC campus (Dandois & Ellis 2010)
The Ecosynth project was completed September 30, 2018.

The Ecosynth Project
developed low-cost user-deployed open-source tools for scanning ecosystems in 3D from sets of digital photographs acquired using light-weight aerial platforms and from the ground.

The Ecosynth community website on Ning was a hub for collaborations for more than 350 early drone and computer vision ecologists from 2012 to 2018. The site closed in August 2019.




An interactive 3D forest viewer was developed.

 


Ecosynth developed the first high temporal resolution multispectral imaging of forest canopies in 3D.
