ArcGIS 3D LiDAR Toolset

ESRI has released a new version of 3D LiDAR toolset, which was designed to extend the LiDAR capabilities of ArcGIS Desktop. It can be downloaded from : http://www.arcgis.com/home/item.html?id=fe221371b77940749ff96e90f2de3d10

cwduyyhweaau4fdFunctionalities of the LiDAR toolset:
  • Classify ground*, building, vegetation, and noise points
  • Extract building footprint approximations
  • Clip LAS files*
  • Improve QA/QC processes with lidar data:
    • Evaluate LAS files for errors through the CheckLAS utility
    • Export LAS file header information
    • Define the spatial reference of LAS files with missing/incorrect information*
    • Project LAS files to desired coordinate systems*
    • Evaluate coverage of overlaps in lidar scans
    • Rearrange LAS files to optimize data access I/O*
  • Optimize lidar data for operational use and rapid access through the compressed ZLAS format
  • Evaluate Z statistics with advanced height metrics*
  • Analyze the proximity of LAS points to 3D features**
  • Convert lidar data between various data formats
  • Create tiled raster derivatives
Analysis & Data Management of 3D Features & Surfaces
  • Correct the Z value of a multipatch model so that it “sits” on the ground
  • Create a point skymap of sun positions for visualization and solar analysis workflows
  • Simplify dense, 3D breaklines to support scalability in TIN-based surface modeling*
  • Integrate a design surface, such as one created using the Grading tool, into a base TIN
  • Export a TIN to LandXML for use in 3rd party applications
  • Cross sections of a multipatch can be used with the Intersect 3D tool to:
    • Generate contours in 3D space that capture cliff overhangs
    • Determine a 3D model’s footprint at different heights
    • Generate sightlines for visibility analysis
