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 info@opentopography.org 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.

7 May 2011 DielmoOpenLidar

Description: DielmoOpenLiDAR is an open source software with GNU GPL license based in gvSIG for the management of LiDAR data. It allows access, visualization and analysis of the original LiDAR data, toguether with the possibility of visualizing at the same time big volumes (hundreds of GigaBytes) of original LiDAR data (irregular points in formats LAS and BIN) along with other geographic data. In the near future, it will also generate basic final products such as (DSM, DTM, intensity images, etc) and new added value final products.

Developing open source software for the management of LiDAR data, we hope to make this technology more accessible to standard GIS users and scientific communities, having as final objective increase the use of LiDAR data.

For developing this application, we had the collaboration of the Regional Valencia Council for Infrastructures and Transportation - CIT and National Geographic Institute of Spain - IGN

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.

26 Jan 2015 Global Mapper

Description: Global Mapper is an affordable and easy-to-use GIS application that offers access to an unparalleled variety of spatial datasets and provides just the right level of functionality to satisfy both experienced GIS professionals and beginning users. Equally well suited as a standalone spatial data management tool and as an integral component of an enterprise-wide GIS, Global Mapper is a must-have for anyone who deals with maps or spatial data.
Global Mapper is more than just a utility; it has built in functionality for distance and area calculations, raster blending, feathering, spectral analysis, elevation querying, line of sight calculations, cut-and-fill volume calculations, as well as advanced capabilities like image rectification, contour generation from surface data, view shed analysis, watershed delineation, sea level rise modeling, terrain layer comparison, and triangulation and gridding of 3D point data.
Users can now simulate fly-through recordings in high-definition with various sky models in the 3D viewer. This new Skybox tool enables users to choose from a handful of existing sky templates or custom designs. Support for 3D textures and meshes have also been added to give data a more realistic look, including support for a host of new 3D formats. Live GPS data can also now be viewed and tracked in the 3D Viewer. Version 16 features dramatically faster processing speeds for analyzing large amounts of data.

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.

28 May 2015 LiVoxGen

Description: LiVoxGen is a C++ program that voxelizes LiDAR data. It outputs a flat file containing voxel (volumetric pixel) information based on the user's parameters and may also output a flat file of metric information for the voxel column centroids. LiVoxGen's purpose is to analyze point densities and forest structure by dividing LiDAR data into voxels.
