ET Surface 7.3 released on 3 July 2022

ET Surface is a set of tools that enable the users to create surfaces and perform surface analysis. ET Surface was initially developed as an extension for ArcGIS.

As from version 7.0 ET Surface is available as a standalone application and can be used by all GIS professionals no matter what is the GIS platform they are using.The only requirement is Windows 7.0 and above.

The functionality of ET Surface 7 is available in several ways:

  • Stand-alone Windows application with user friendly interface and integrated User Guide.
  • From within ET SpatialDataViewer - a simple free viewer.
  • Seamlessly integrated in ArcGIS Desktop via:
    • ArcGIS Desktop add-in that starts ET Surface dialog from ArcMap.
    • An ArcGIS toolbox that allows the functionality to be executed from ArcToolbox, included in a Model using the Model Builder or ArcPy scripts.
  • Seamlessly integrated in ArcGIS Pro via:
    • ArcGIS Pro add-in that starts ET Surface dialog from within the ArcGIS Pro interface.
    • An ArcGIS Pro Toolbox that allows the functionality to be executed from ArcToolbox, included in a Model using the Model Builder or ArcPy scripts.
  • All the functions can be executed using Python (no third party software required).
  • The tools can be integrated in custom .NET applications (no third party software required).
  • The functionality can be executed directly from the DOS Command Prompt.

ET Surface 7 is a native 64-bit application

  • This allows handling very large datasets at impressive speed.
  • The functionality however can be executed from any 32-bit application (example - ArcMap).

ET Surface 6.3

ET Surface version 6.3 is a legacy version which is:

  • A 32-bit extension for ArcGIS Desktop.
  • Fully supported.
  • Can be used on the same computer where ET Surface 7 is installed.

  • Users without ArcGIS
    • Via a stand-alone application with user friendly interface and integrated User Guide.
    • From within our free ET SpatialDataViewer application.
    • Using Python scripts.
    • Using custom .NET applications.
    • From DOS command prompt.
  • Users with ArcGIS
    • All of the methods above.
    • From ArcGIS Desktop and ArcGIS Pro using the Add-Ins provided.
    • Using the toolboxes provided for ArcGIS Desktop and ArcGIS Pro.
    • From Models created using the Model Builder in ArcGIS Desktop and ArcGIS Pro.
    • From ArcPy scripts.

All functions available in the previous versions of ET Surface are available in version 7.0 and produce exactly the same results.

Purchase and Register

Limitations of the unregistered software

The unregistered version of ET Surface has all the functionality of the Full version. It has no time limit, but has the following restrictions:

  • Build TIN function will use the first 500 points of the input feature class only.
  • Modify TIN will work with input TIN with 500 nodes or less and will use the first 500 points or vertices of the input feature class only.
  • Any function with raster output will work without restrictions, but if the output raster has more than 10,000 cells it will have a stamp with NoData cells.
  • Any function with TIN input will work only if the input TIN has 500 nodes or less.
  • The functions for which the main data source are feature classes, will not work on feature classes with more than 100 features.
  • Profiling, Line of Sight, and Digitize Z features functions will use the first 50 data points only.
