IGIS Tech Notes: Embedding Phodar Point Clouds Online

IGIS Tech Notes describe workflows and techniques for using geospatial science and technologies in research and extension. They are works in progress - we welcome feedback! To open links in a new tab, use ctrl+click or open this doc in a new window.



"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.
