This resource provides bulk downloads of point cloud data from datasets hosted by OpenTopography. It is designed for advanced users seeking to download large amounts of data quickly and who have the bandwidth, expertise, and software necessary to manage the gigabytes of data available. We expect that users accessing bulk data have the ability to automate downloads using AWS Command Line Interface or other compatible GUI clients.

A 2018 pre-event digital elevation model with 1.5 m postings was generated from 40 cm resolution stereo digital imagery collected by Hexagon Inc. The aerial images were captured from July 22, 2018 to September 1, 2018. A process called semi global matching (Gehrke et al., 2012) was applied to the imagery to automatically generate a DEM. OpenTopography is providing access to the point cloud derived from the DEM.
