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.

9 Nov 2011	FME Description: FME empowers users at leading organizations worldwide to transform spatial data so that they can use and share it wherever, whenever, and however its needed. FMEs unmatched capabilities and support for 250+ spatial and non-spatial formats enable you to quickly overcome any challenge related to the use and sharing of spatial data, so you can focus your energies on your objectives, instead. Specifically, FME supports LiDAR data formats, enabling you to leverage the wealth of information in your LiDAR assets by enabling you to quickly prepare your LiDAR data to suit your specific needs. Safe Software, the maker of FME, is the pioneering global leader in the spatial data transformation technology market.

4 Sep 2014	CHaMP Transformation Tool Description: The Ecogemorphology & Topographic Analysis Lab (ET-AL) and the RSGIS Laboratory developed this ArcGIS Add-in for the transformation and projection of CHaMP field survey data (Bouwes et al. 2011) into real world coordinates given hand-held GPS coordinates from just three benchmarks. The CTT will work with any unprojected data in a file geodatabase, and gives you multiple ways to do an afine transformation based on a simple shift and rotation. Although other transformation tools exist in ArcGIS, there is not a simple sequence of geoprocessing tools, which allow you to transform vector data in a manner that preserves the high relative accuracy of a total station survey. See Wheaton et al. (2012) and the ReadMe page for more background.	Data Management / Handling	transformation, georeferencing point cloud	(0 rating)
5 Mar 2015	Geographic Calculator Description: The Geographic Calculator is THE Global Coordinate Transformation tool for any coordinate or geomatic challenge. A powerful windows solution with particular strength in survey, seismic and energy exploration, it is available in 32 or 64 bit versions. This highly accurate transformation software includes tools such as Canadian DLS (Dominion Land Survey) Land Grid tools, Seismic Survey Conversion tools, Area of Use tools for guiding users, and much more. The Geographic Calculator supports a wide range of file formats with support from the largest geodetic parameter database available anywhere. Display and reproject your DEMs into the right coordinate systems.
