Generate tessellations

A generate tessellations analysis resulting in a new layer with 1 mile hexagon bins created for a study area in Auckland.

What is a generate tessellation analysis?

A generate tessellation analysis is the process of creating equally sized square, hexagon, triangle, or diamond geometry bins for an area or extent. To execute the analysis, use the and the GenerateTessellations operation.

generate tessellations

You typically generate tessellations to create regularly shaped areas that can be used in subsequent analysis.

Real-world examples of this analysis include the following:

  • Enriching the polygons with data from the .
  • Aggregating and summarize high-density point data.
  • Visualizing how best to allocate resources for projects such as reforestation.

How to generate tessellations

  1. Review the parameters for the GenerateTessellations operation.
  2. Send a request to get the spatial analysis service URL.
  3. Execute a job request with the following URL and parameters:
    • URL: https://<YOUR_ANALYSIS_SERVICE>/arcgis/rest/services/tasks/GPServer/GenerateTessellations/submitJob
    • Parameters:
      • binType: The tessellation shape.
      • binSize: The size of each bin.
      • outputName: A string representing the name of the hosted feature layer to return with the results.
  4. Check the status.
  5. Get the output layer results.
