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 | xyzRotatorDH | 30 Nov 2010 | Point Cloud Analysis |  |
|
Keywords: rotation, translation, georeferencing, point cloud
License: GNU General Public License Description: A MATLAB script that takes an unreferenced 3-column xyz dataset (e.g., a TLS point cloud) and places it in a Cartesian global coordinate system (e.g., UTM) given at least one known global point (e.g. from a hand-held GPS unit). |

| 2 | xyzRotatorDH_Linux | 30 Nov 2010 | Point Cloud Analysis |  |
|
Keywords: rotation, translation, georeferencing, point cloud
License: GNU General Public License Description: A Linux (Korn) shell script that takes an unreferenced 3-column xyz dataset (e.g., a TLS point cloud) and places it in a Cartesian global coordinate system (e.g., UTM) given at least one known global point (e.g. from a hand-held GPS unit). |

| 3 | CHaMP Transformation Tool | 4 Sep 2014 | Data Management / Handling | |
|
Keywords: transformation, georeferencing point cloud
License: GNU General Public License Description: The Ecogemorphology & Topographic Analysis Lab (ET-AL) and the RSGIS Laboratory developed this ArcGIS Add-in for the transformation and projection of CHaMP field survey data (Bouwes et al. 2011) into real world coordinates given hand-held GPS coordinates from just three benchmarks. The CTT will work with any unprojected data in a file geodatabase, and gives you multiple ways to do an afine transformation based on a simple shift and rotation. Although other transformation tools exist in ArcGIS, there is not a simple sequence of geoprocessing tools, which allow you to transform vector data in a manner that preserves the high relative accuracy of a total station survey. See Wheaton et al. (2012) and the ReadMe page for more background. |

| 4 | LIDAR Widgets | 6 May 2016 | Visualization, Point Cloud Analysis, DEM generation, DEM Analysis, Data Management / Handling, Software Suite | |
|
Keywords: contour map, mesh, grid, DXF, AutoCAD, ArcInfo, ESRI, point cloud, terrain, LAS, LAZ
License: Commercial License Description: LIDAR Widgets is a suite of programs that will process LAS/LAZ point files and generate 3D terrain models and contour maps. Output formats include AutoCAD DXF, ESRI ArcInfo grids, and QwtPlot3D viewable meshes with real-time pan, zoom and rotation. Converts LAS/LAZ point clouds into DXF point clouds. Also batch converts LAS/LAZ files into viewable mesh files, contour maps, 3D models, DXF point clouds or ArcInfo meshes. |
