Is it possible to create sites from a heat map in the Business Analyst web app?

Answer

No, it is not possible to create sites from a heat map created in the Business Analyst web app because the heat map is just a dynamic symbology option for the point dataset and the heat map polygons are not selectable features. A possible workaround is to create the heat map in ArcGIS Online using the Calculate Density tool and add this map to the Business Analyst web app to create sites.

1. In ArcGIS Online, add the desired point data to create the heat map. Refer to the following document on how to add items to ArcGIS Online: Add items.
2. Open the added feature layer in the ArcGIS Online map viewer.
   • In the My Content tab, search for the added feature layer, and click the ellipsis icon > Open in Map Viewer.
3. Run the Calculate Density tool to create the heat map.
   1. Click Analysis > Analyze Patterns > Calculate Density.
   2. In the Calculate Density pane, select the point layer from which to calculate the density.
   3. Optionally, select a count field.
   4. Set a name and location for the result layer.  
      
      
       
   5. Click RUN ANALYSIS. A new feature layer is displayed in the map displaying the point density result.
4. Log in to bao.arcgis.com and add the heat map created in Step 3 to the map within the desired project.
   1. In the project, click Add Data > Web Maps and Layers.
   2. In the Browse ArcGIS dialog box, search for the heat map, and click Add this map.  
      
      
       
5. Select the polygons of the added heat map to create a site. The created site is saved to [Project name] > Polygons (Sites) > My Polygons.
   1. Click to select the polygon or press Shift and drag the pointer to select multiple polygons.
   2. Click Yes in the dialog box to combine the selected sites into one site.
