Sharing Digital Aerial Photogrammetry (DAP) Point Clouds with Potree

IGIS Tech Notes describe workflows and techniques or using geospatial science and technologies in research and extension. They are works in progress, and we welcome feedback and comments below.


Digital Aerial Photogrammetry (DAP), also known as 'Phodar', refers to a 3D point cloud derived from photogrammetric processing of aerial photos, such as those taken by a drone. The points in these clouds have been extracted from photos taken from different angles, so what looks like a surface is actually millions of little pieces from hundreds of photos.

This Tech Note describes options for sharing Phodar data online through interactive visualizations like the one below.
