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. Points2Grid offers two processing modes - in-core and out-of-core - to allow it to handle generation of rasters larger than available memory.
Version 1.0 of Points2Grid offers the following features:
Points2Grid is open source and offered under a modified BSD license as required by the University of California Regents.
Version 1.0 of Points2Grid can be downloaded from OpenTopopgraphy's space on sourceforge.net, otforge at: https://sourceforge.net/projects/otforge/files/points2grid/1.0/
