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.

3 Apr 2011 SAGA GIS

Description: SAGA GIS is a FOSS which is, besides common GIS tasks, specialized on digital terrain analysis. The software provides a lot of analysis tools which you will not find in any other software package, e.g. for morphometric or hydrologic analysis. SAGA supports various raster and vector (including LAS and SAGA point clouds) formats, DEM generation, analysis and visualization (e.g. 3D point cloud viewer, bare earth extraction). One of SAGA's main objectives is to provide scientists an easy to use API to implement own algorithms (C++) but it is also used in commercial environments. SAGA provides a GUI and can be scripted in various ways (e.g. batch/bash, python). SAGA runs on Windows, Linux and FreeBSD, both 32 and 64bit. The software is licensed under the GPL (GUI, most of the modules) and the LGPL (API).

20 Mar 2014 LIDAR Analyst

Description: LIDAR Analyst® software is the premier feature extraction solution for airborne LIDAR data, allowing geospatial analysts to unlock the value of LIDAR by automatically extracting 3D objects such as bare earth, trees or buildings. Now the software has been upgraded with a major enhancement: an integrated 3D Viewer that delivers mission-critical high-resolution 3D exploitation and further establishes LIDAR Analyst as the Gold Standard. Enjoy the performance of viewing and manipulating LIDAR data containing over a billion points.
LIDAR Analyst has eight years of proven heritage as one of the first commercially released LIDAR applications. The power, speed, accuracy and broad selection of tools enable users to get real work accomplished. Thats why LIDAR Analyst is so widely respected and used daily by military forces, federal agencies, local governments, academic universities and GIS services providers around the globe. Since LIDAR Analyst is an extension for Esri ArcGIS®, the products familiar environment makes it easy to install and learn.
Use the 3D Viewer to manipulate, filter and edit LIDAR point clouds displayed in stunning color. Rapidly inventory all the buildings across a city or area of interest by using LIDAR Analysts advanced algorithms to detect, recognize, and extract complex 3D building shapes. Count the trees in a forest or scattered throughout a neighborhood. Strip away the buildings and shrubbery to reveal the true ground level for detailed terrain.

4 Sep 2014 ToPCAT = Topographic Analysis Toolkit

Description: Topographic Point Cloud Analysis Toolkit (ToPCAT) is a software package developed by Brasington et al. (2012) used to decimate (or thin) a point cloud and calculate meaningful statistics for grid defined areas. The process of decimation can reduce computation time and produce meaningful summary outputs (e.g. zMin for modeling bare earth elevations; and detrended standard deviation for modelling surface roughness).

10 Mar 2015 Tiffs (Toolbox for Lidar Data Filtering and Forest Studies)

Description: Tiffs (Toolbox for Lidar Data Filtering and Forest Studies) is a professional software that is highly automatic, very fast, and accurate in generating bare earth models, digital surface models, digital height models, and extracting forest information from individual trees to regional scales.

Tiffs was featured in the cover of the 2007 February issue of Photogrammetric Engineering & Remote Sensing (PE&RS), the official journal of photogrammetry and geospatial society in the U.S. The core algorithms in Tiffs have won a couple of prestigious awards including the Best Paper Award in the Remote Sensing Specialty Group of Association of American Geographer in 2005. Most of the algorithms are published in the peer-reviewed journal PE&RS. The filtering algorithm was validated with the benchmark dataset provided by ISPRS (the International Society of Photogrammetry and Remote Sensing). The comparison with the other well-known algorithms showed that our algorithm achieved the best overall accuracy. The tree isolation method used a conquer-and-divided strategy and has the advantages of minimizing both omission (missing trees) and commission (overcounting trees) errors. The canopy structure estimation is based on an innovative metric called canopy geometric volume, which has solid scientific roots in plant allometry.
