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.

21 Nov 2014 fleurdelas

Description: The fleurdelas class is an IDL/ENVI implementation of a LAS file reader/writer. The class object can read, write and manipulate points and/or full waveforms contained in the binary LAS file format. It can handle any LAS 1.0, 1.1, 1.2, 1.3 and 1.4 with point format from 0 to 10. This class object therefore is very well suited to access the point structure information or the waveform information for further process. It can also filter the point cloud and generate new LAS file. However, if you need to manipulate; the Variable Length Records or the Coordinates System we will recommend you to use LAStools as it is more adapted for this purpose.

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.

4 Sep 2014 ToPCAT = Topographic Analysis Toolkit

Description: Topographic Point Cloud Analysis Toolkit (ToPCAT) is a software package developed by Brasington et al. (2012) used to decimate (or thin) a point cloud and calculate meaningful statistics for grid defined areas. The process of decimation can reduce computation time and produce meaningful summary outputs (e.g. zMin for modeling bare earth elevations; and detrended standard deviation for modelling surface roughness).

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

7 Jul 2016 ARSF DEM Scripts

Description: A collection of scripts developed by the Natural Environment Research Council (NERC) Airborne Research Facility Data Analysis Node (NERC-ARF-DAN; formerly ARSF) for generating DEMs from point clouds.
Through command line tools or Python functions the ARSF DEM Scripts provide a common interface to generate DSMs or DTMs from LAS files using GRASS, SPDLib, points2grid, FUSION or LAStools. When using SPDLib, FUSION or LAStools will classify ground returns to produce a DTM (note license required to produce a DTM using LAStools).
Additional utilities are available for manipulating DEMs (e.g., patching with a courser resolution DEM to fill in gaps) using GRASS.
