Points2Grid Lidar Gridding Code Open Source Release

Jun 24, 2011

We're pleased to formally announce the open source release of the OpenTopography-developed Points2Grid algorithm for Digital Elevation Models generation from lidar point cloud data. Points2Grid is a robust and scalable local gridding tool for processing LIDAR point cloud data to DEMs. The algorithm uses a local gridding method to compute grid cell elevation using a neighborhood defined around each cell based on a search radius provided by the user.

Planned Outage May 3rd until 12 pm
