12   Geomorphic Change Detection Software 4 Sep 2014 DEM Analysis
Keywords: DEM error modelling, change detection, DEM uncertainty, geomorphic interpretation
License: Other

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.

    53   Civil Maps 19 Mar 2015 Visualization, Point Cloud Analysis, Data Management / Handling
    Keywords: deep learning, artificial intelligence, point cloud streaming protocol
    License: Other

    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

    License: GNU General Public License

    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.

    License: Free to use/Unspecified

    Description: The FUSION/LDV analysis and visualization system consists of two main programs, FUSION and LDV (LIDAR data viewer), and a collection of task-specific command line programs. The primary interface, provided by FUSION, consists of a graphical display window and a control window. The FUSION display presents all project data using a 2D display typical of geographic information systems. It supports a variety of data types and formats including shapefiles, images, digital terrain models, canopy surface models, and LIDAR return data. LDV provides the 3D visualization environment for the examination and measurement of spatially-explicit data subsets. Command line programs provide specific analysis and data processing capabilities designed to make FUSION suitable for processing large LIDAR acquisitions.

    Command line utilities and processing programs, called the FUSION LIDAR Toolkit or FUSION-LTK, provide extensive processing capabilities including bare-earth point filtering, surface fitting, data conversion, and quality assessment for large LIDAR acquisitions. These programs are designed to run from a command prompt or using batch programs.

    FUSION runs on all current versions of Windows and has been successfully used on LINUX systems using WINE. The FUSION/LDV visualization system is GUI based. The command line tools require the use of batch files to be most effective.
