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.

3 Apr 2011 SAGA GIS

Description: SAGA GIS is a FOSS which is, besides common GIS tasks, specialized on digital terrain analysis. The software provides a lot of analysis tools which you will not find in any other software package, e.g. for morphometric or hydrologic analysis. SAGA supports various raster and vector (including LAS and SAGA point clouds) formats, DEM generation, analysis and visualization (e.g. 3D point cloud viewer, bare earth extraction). One of SAGA's main objectives is to provide scientists an easy to use API to implement own algorithms (C++) but it is also used in commercial environments. SAGA provides a GUI and can be scripted in various ways (e.g. batch/bash, python). SAGA runs on Windows, Linux and FreeBSD, both 32 and 64bit. The software is licensed under the GPL (GUI, most of the modules) and the LGPL (API).

7 May 2011 DielmoOpenLidar

Description: DielmoOpenLiDAR is an open source software with GNU GPL license based in gvSIG for the management of LiDAR data. It allows access, visualization and analysis of the original LiDAR data, toguether with the possibility of visualizing at the same time big volumes (hundreds of GigaBytes) of original LiDAR data (irregular points in formats LAS and BIN) along with other geographic data. In the near future, it will also generate basic final products such as (DSM, DTM, intensity images, etc) and new added value final products.

Developing open source software for the management of LiDAR data, we hope to make this technology more accessible to standard GIS users and scientific communities, having as final objective increase the use of LiDAR data.

For developing this application, we had the collaboration of the Regional Valencia Council for Infrastructures and Transportation - CIT and National Geographic Institute of Spain - IGN

24 May 2012 SPD Software Library (SPDLib)

Description: SPDLib is a set of open source software tools for processing laser scanning data (i.e., LiDAR), including both discrete return and waveform data captured from airborne and terrestrial platforms. The aim of the software is provide you, the user, with the tools you need to process these data. The software has grown from research carried out at Aberystwyth University and Queensland University concerning the processing of LiDAR data for vegetation analysis and has continued to grow. One of the key features which differentiates this software from other LiDAR software is the ability to process and store full waveform datasets alongside traditional discrete return data

18 Feb 2013 Optimized Pit Removal

Description: ArcGIS (version 10.1) geoprocessing script tools for removing pits (or sinks) from Digital Elevation Models using a combination of cut and fill. This alternative to the standard Fill tool provides more realistic flow paths with less required manual adjustment. Ideal for high-resolution datasets such as LiDAR.

The tool also allows users to mark specific depressions to be left unmodified by setting the lowest cell to have a value of No Data. This feature can be used to establish reservoirs as well as known drainage features such as storm sewer inlets.

Also contains a C++ executable that can be run via command line inputs independent of ArcGIS, and which operates on ASCII grid files.

4 Sep 2014 Geomorphic Change Detection Software

Description: The GCD software was developed primarily for morphological sediment budgeting in rivers. The volumetric change in storage is calculated from the difference in surface elevations from digital elevation models (DEMs) derived from repeat topographic surveys. As each DEM has an uncertain surface representation (which might vary in space and time), our ability to detect changes between surveys is highly dependent on surface representation uncertainties inherent in the individual DEMs. The fundamental problem is separating out the changes between the surveys that are due to geomorphic change as opposed to noise in the survey data. GCD provides a suite of tools for quantifying those uncertainties independently in each DEM and propagating them through to the DEM of difference. The program also provides ways for segregating the best estimates of change spatially using different types of masks. The overall suite of tools is more generically applicable to many different spatial raster-based change detection problems.

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.

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.
