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.

30 Mar 2011	VRMesh Survey: LiDAR Point Cloud Classification Tool Description: Vrmesh Survey is an intelligent solution for automatic point cloud classification and bare-earth extraction. It automatically and accurately classifies LIDAR point clouds into ground, vegetation, building, and others. More than 90% identification jobs will be done in a one-click process. Manual adjustments can be easily performed in a cross section view. It also provides comprehensive functionalities to generate accurate triangle meshes.

6 Jul 2016	terrainShadingMask Description: terrainShadingMask is a free collection of terrain masks for various locations. They are given in geometrical (.obj files) and textual (.hor files) forms. A terrain shading mask is a diagram which maps the silhouette of the surrounding terrain (hills, valleys, mountains, tree tops...) around the chosen location. Building simulation softwares (IES VE, Trnsys 3D, Design Builder...) can use the .obj geometry files, while solar-photovoltaic-thermal software (PV*SOL, PVsyst...) can use .hor files.
