OpenTopography Tool Registry
Welcome Guest ( Sign Out )
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.
Appearance of a tool in the OpenTopography Tool Registry does not imply endorsement, recommendation, or support, by the NSF OpenTopography Facility and is meant simply as a service to our users. OpenTopography does not guarantee the completeness or accessibility of specific content and links contributed by users. If you have been directly involved with the development of a registered tool and are not the original contributor of the tool to the registry, please email info@opentopography.org to supply updates or modifications to its entry.

| 1 | Points2Grid | 23 Jun 2011 | DEM generation |  |
|
Keywords: gridding, P2G, point cloud, binning, local gridding, DEM
License: BSD license 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. |

| 2 | Points2Grid Utility (winP2G) | 20 Nov 2010 | DEM generation |  |
|
Keywords: point cloud, lidar, DEM, gridding, binning
License: Free to use/Unspecified 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 |
