Read the full news item...Today we corrected a significant bug in the OpenTopography point cloud access and processing system that was introduced at the OT 2.2 release two weeks ago. The bug, which we missed in beta testing, also went unreported by users over the past two weeks despite significantly impacting data products generated by OpenTopography. Specifically, the bug interfered with the ability to select a subset of point cloud data based on point cloud classification type (e.g. “ground only"). This means that regardless of what classification was selected by the user, the system returned all points in a selected area. The bug affected seven out of eleven OT-hosted datasets.

This release - OpenTopography v 2.2 - provides a much needed improvement to our standard digital elevation model (DEM) download interface. The new system makes it considerably easier to select and download many files at once, and also fixes issues that were causing stalled downloads in the previous system. We’ve also updated the OpenTopography Points2Grid algorithm to improve processing speed on custom DEM generation from LiDAR point cloud data, and have made a number of tweaks to the OpenTopography website design and organization.
