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.

30 Nov 2010 xyzRotatorDH

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).

3 Dec 2010 GDAL - Geospatial Data Abstraction Library

Description: GDAL is a translator library for raster geospatial data formats that is released under an X/MIT style Open Source license by the Open Source Geospatial Foundation. As a library, it presents a single abstract data model to the calling application for all supported formats. It also comes with a variety of useful commandline utilities for data translation and processing.

GDAL is a powerful tool for converting digital elevation model (DEM) formats, performing coordinate system conversions, and the gdaldem utility provides basic processing functionality such as generation of hillshades and slope maps.

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.
