ET Surface - History
ET Surface 3.0 - released 3 July 2010

Entirely redeveloped in Microsoft .NET Framework.

Fully compatible with ArcGIS 10.

Compatible with Windows XP, Vista and 7 (32 and 64 Bit).

New main dialog with built-in help.

New functionality
  • ToolBox implementation of all functions added. The functions can be used within Arc Toolbox, Model Builder and Python scripts.
  • ET TerrainViewer
    • Areal photography can be draped over the surface layer
    • Significantly improved symbology
    • Introduced a graphic layer where the user can interactively place point objects on the surface
    • Journey function - the user can define route and walk/fly along this route.
    • New environment settings - the user can select sky box and apply fog to the scene.
  • Profile Extractor
    • Entirely redeveloped interface
    • Unlimited surface layers can be used for profiling
    • The user can save the profile with all settings into a project file
    • Feature layers can be displayed on the profile with labels (draped on a surface or with their Z values).
    • Borehole data can be represented on the profile.
  • Raster Calculator - enables the user to perform complex mathematical calculation on rasters
  • Interpolate Kernel Density Surface
  • Zonal Statistics - calculates raster statistics for the features of a polygon dataset.
  • Split PolylineZ based on slope changes.
  • Clean Spikes in PolylineZ.

Improved

  • Some of the functions can be applied on 3 band rasters
    • Clip with Envelope
    • Clip with Polygons
    • Erase with Polygons
  • Better handling of NoData values

Bugs fixed

  • A bug in the user interface of the Clip and Erase functions
  • Incorrect values for the Average Slope calculated by the PolylineZ Characteristics function
  • A bug in the Multipatch To Polygon function
