3 Nov 2011	CloudCompare Description: CloudCompare is a 3D point cloud and triangular mesh processing software. It has been originally designed to perform fast cloud/cloud or cloud/mesh comparison on huge datasets such as those acquired by laser scanners). Afterwards, it has been extended to a more generic 3D data editing and processing software.	Point Cloud Analysis	3D point cloud mesh comparison editing processing lidar laser scanner	(3 ratings)
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.

12 Jan 2017	planlauf/TERRAIN Description: planlauf/TERRAIN is an easy-to-use application for Windows 7/8/10 to visualize Digital Elevation Models. It uses state-of-the-art techniques from the gaming industry like 'Mesh Decimation', 'Normal Mapping' and 'Level of Detail' to reduce the size of the models significantly while preserving the visual details of the original model. A 30 day trial version without any restrictions is available.	Visualization, Point Cloud Analysis, DEM generation, DEM Analysis		(0 rating)
6 May 2016	LIDAR Widgets 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.
