FAQ: Is it possible to count the number of point features within drive time polygons in Business Analyst Web App?

Question

Is it possible to count the number of point features within drive time polygons in Business Analyst Web App?

Answer

While it is not possible to count the number of point features within drive time polygons in Business Analyst Web App, a possible workaround is to export the points layer and drive time polygons to ArcGIS Online and run the Summarize Within tool. To do so, follow the steps below:

  1. In Business Analyst Web App, share the points layer and the drive time polygons to ArcGIS Online.
    1. Click Share map to ArcGIS An image of the Share map to ArcGIS icon..
    2. In the Share Map dialog box, provide a title, description, the relevant tags, and click Share.

      The Share Map dialog box.
  2. Log in to www.arcgis.com and navigate to My Content > BA - My Maps.
  3. Select the desired web map to view the item details page, and click Open in Map Viewer.
  4. Run the Summarize Within tool to calculate the number of point features within each drive time polygon.
    1. Click Analysis > Summarize Data > Summarize Within.
    2. In the Summarize Within pane, select Polygon, and select the drive time polygons layer in Choose the polygon layer.
    3. In Choose a layer to summarize, select the points layer.
    4. Set a name for the Result layer name and location of the output result.

  5. Click Run Analysis. A new layer is added to the Map Viewer containing information of the number of point features within each drive time polygon.

    To view the count of point features in each drive time polygon, open the attribute table of the result layer. The figure below shows the point feature count of three drive time polygons.

The result layer is saved as a hosted feature layer in the location specified in step 4(d). The layer can be exported to various output formats such as a CSV file, file geodatabase, or shapefile using the Extract Data tool in ArcGIS Online.
