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 to supply updates or modifications to its entry.

19 Nov 2010 LViz: 3D LiDAR Visualization Tool

Description: LViz is a tool designed for 3D visualization of LiDAR point cloud and interpolated data, the tool offers import of LiDAR point cloud data (delimited text file) or interpolated surfaces (in ascii or arc ascii grid formats). LViz also offers texture mapping and user control over display settings such as data and background color. LViz was originally written for visualization of outputs from the GEON LiDAR Workflow system and is designed to run on Windows platforms. Although originally conceived for the 3D visualization of LiDAR data, LViz can be used to view any 3D point cloud data such as seismicity or gravity.

23 Sep 2014 TerEx

Description: The TerEx Tool automates the process of mapping terraces and floodplains from high resolution topography data (works best on <3m grid resolution). The tool maps terraces and floodplains from user-defined parameters including, a local-relief threshold selected by a variable-size moving window, minimum area threshold, and maximum distance from the channel to identify and map discrete terrace and floodplain surfaces. Subsequently, the tool automatically measures planform area, absolute elevation, and height relative to the local river channel for each terrace polygon. TerEx can be run in a Python environment or as a GUI plugin for ArcMap. See Stout and Belmont, 2014 and the users manual for explanations of tool functionality and several test cases that provide guidance on parameter values for a wide range of landscapes.

19 Mar 2015 Civil Maps

Description: Civil Maps allows users to upload their survey data, then specify the assets of interest and mapping specification. Upon upload, Civil Maps indexes all of the spatial information as defined in the mapping specification into a query-able format. The maps can then be dynamically generated on demand and exported to various tools such as AutoDesk Map3D from Civil Maps, which is useful for integrating into the customers workflow. The biggest pain point in the industry is the time to annotate 3D scans. Currently, processing huge 3D survey datasets is limited by the point­ and ­click annotation speed of the user and the limited resources of the users computer (I/O, CPU, Network, Memory).

By circumventing these bottlenecks, Civil Maps is introducing a paradigm shift in the workflow of annotating 3D survey data. Advancements in parallel computing and deep learning allows Civil Maps to reduce 2 years of manual annotation work down to 2 days of processing using our cloud infrastructure

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.
