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.

	Tool Name	Date	Tool Type	Rating
1	Global Mapper	26 Jan 2015	Visualization, Point Cloud Analysis, DEM generation, DEM Analysis
Keywords: GIS, LiDAR, file format translation, data analysis, 3D, Vector Raster, image rectification, contour License: Commercial License 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.
2	Global Mapper LiDAR Module	5 Mar 2015	Visualization, Point Cloud Analysis
Keywords: automatic point cloud classification, feature extraction, cross-sectional viewing and editing, drama License: Commercial License Description: The Global Mapper LiDAR Module is an optional enhancement to the software that provides numerous advanced LiDAR processing tools, including automatic point cloud classification, feature extraction, cross-sectional viewing and editing, dramatically faster surface generation, and much more. At a fraction of the cost of comparable applications, it is a must-have for anyone using or managing LiDAR data.
