The OpenTopography Tool Registry provides a community populated clearinghouse of software, utilities, and tools oriented towards high-resolution topography data (e.g. collected with lidar technology) handling, processing, and analysis. Tools registered below range from source code to full-featured software applications. We welcome contributions to the registry via the Contribute a Tool page.

23 Jun 2011	Points2Grid Description: Points2Grid is a robust and scalable tool for gridding LIDAR point cloud data to generate Digital Elevation Models (DEMs). Points2Grid 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 (see image below). Points2Grid offers two processing modes - in-core and out-of-core - to allow it to handle generation of rasters larger than available memory.

20 Nov 2010	Points2Grid Utility (winP2G) Description: The Points2Grid Utility is a simple tool for the generation of Digital Elevation Models (DEMs) from lidar point cloud data. The Points2Grid Utility is a Windows application that utilizes the same local binning algorithm deployed in the OpenTopography lidar system to offer rapid generation of DEMs from large volumes of LiDAR point return data. Note that winP2G is no longer supported - information about newer implementations of the algorithm can be found here: https://opentopography.org/otsoftware/points2grid	DEM generation	point cloud, lidar, DEM, gridding, binning	(4 ratings)
