OpenTopography Tool Registry

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 to supply updates or modifications to its entry.

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.

18 Mar 2011 River Bathymetry Toolkit (RBT)

Description: The (RBT) is available for free and is under active development. Tools exist for cutting cross sections and longitudinal profiles into high resolution DEMs to extract hydrologic parameters such as wetted area, bankfull width, hydraulic radius, gradient and sinuosity. It is possible to save the cross section properties as a ShapeFile and then add them to a map. Using an automated detrending algorithm we are able to remove the overall valley slope. Tools are being created that use the detrended raster to investigate flooding outside a main channel at any prescribed discharge or flow stage.

4 Sep 2014 Geomorphic Change Detection Software

Description: The GCD software was developed primarily for morphological sediment budgeting in rivers. The volumetric change in storage is calculated from the difference in surface elevations from digital elevation models (DEMs) derived from repeat topographic surveys. As each DEM has an uncertain surface representation (which might vary in space and time), our ability to detect changes between surveys is highly dependent on surface representation uncertainties inherent in the individual DEMs. The fundamental problem is separating out the changes between the surveys that are due to geomorphic change as opposed to noise in the survey data. GCD provides a suite of tools for quantifying those uncertainties independently in each DEM and propagating them through to the DEM of difference. The program also provides ways for segregating the best estimates of change spatially using different types of masks. The overall suite of tools is more generically applicable to many different spatial raster-based change detection problems.

5 Mar 2015 Geographic Calculator

Description: The Geographic Calculator is THE Global Coordinate Transformation tool for any coordinate or geomatic challenge. A powerful windows solution with particular strength in survey, seismic and energy exploration, it is available in 32 or 64 bit versions. This highly accurate transformation software includes tools such as Canadian DLS (Dominion Land Survey) Land Grid tools, Seismic Survey Conversion tools, Area of Use tools for guiding users, and much more. The Geographic Calculator supports a wide range of file formats with support from the largest geodetic parameter database available anywhere. Display and reproject your DEMs into the right coordinate systems.

29 Jul 2015 lidar2dems

Description: The lidar2dems project is a collection open-source (FreeBSD license) command line utilities for supporting the easy creation of Digital Elevation Models (DEMs) from LiDAR data. lidar2dems uses the PDAL library (and associated dependencies) for doing the actual point processing and gridding of point clouds into raster data.

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.

7 Jul 2016 ARSF DEM Scripts

Description: A collection of scripts developed by the Natural Environment Research Council (NERC) Airborne Research Facility Data Analysis Node (NERC-ARF-DAN; formerly ARSF) for generating DEMs from point clouds.
Through command line tools or Python functions the ARSF DEM Scripts provide a common interface to generate DSMs or DTMs from LAS files using GRASS, SPDLib, points2grid, FUSION or LAStools. When using SPDLib, FUSION or LAStools will classify ground returns to produce a DTM (note license required to produce a DTM using LAStools).
Additional utilities are available for manipulating DEMs (e.g., patching with a courser resolution DEM to fill in gaps) using GRASS.
