Commercial GIS Extension for Visualization of Large Unstructured Geospatial Data

ProLogic, Inc.

Fairmont, WV 

Enables the visualization and analysis of large unstructured geospatial datasets, such as LIDAR (Light Detection And Ranging) point cloud data, within a commercial desktop Geographic Information System (GIS)

LiDAR ExplorerTM for ArcGISTM:

    • Offers users new ability to interactively visualize and analyze very large geospatial point datasets at full resolution
    • Is provided as an extension to ArcGIS Framework, thus:
      • leverages geospatial data and geoprocessing techniques supported by ArcGIS;
      • extends capability without requiring users to learn a new software interface; and
      • allows interactive browsing of data combined with traditional GIS datasets
    • Provides a processing framework for domain experts to implement analysis techniques
    • LiDAR terrain mapping has become the preferred commercial technique for collection of topographic, forest structure and building shape data, and ArcGIS is the market leader in Geographic Information Systems
    • LiDAR Explorer enables the large and diverse community of ArcGIS users to incorporate the original LiDAR point data directly into their mapping projects and improve product generation workflow
    • LiDAR Explorer v1.1 is now  available ( and improvements planned for v2.0, expected to be released in 2007, are underway
    • These tools are vital to NASA’s research and development agenda and are also important to government agencies with operational mapping responsibilities
    • Examples where these tools can have major role include:
        • Planetary Science: NASA’s LiDAR instruments in orbit around solar system planets and moons map their surface topography with unprecedented accuracy, including MOLA at Mars, MLA in transit to Mercury, and LOLA under development for NASA’s return to the Moon
        • Earth Science: NASA airborne and satellite LiDARs, including ATM, LVIS, and GLAS aboard ICESat, are revealing details previously unseen about ice sheet and glacier elevation change, forest structure, and natural hazards such as coastal erosion
        • Mobility: The DoD Rapid Terrain Visualization program utilizes high-resolution LiDAR data around the globe for logistical support purposes by mapping ground topography  beneath vegetation, delineating and charac-terizing trees and buildings, and detecting road and utility networks
