Adding the Flow Layer

Create a flow map by connecting two sets of location dimensions within your dataset.

Prerequisites

To add data from a model to a flow layer, the model must contain at least two location dimensions. For more information see Creating a Model with Coordinate or Area Data for Geospatial Analysis.

Procedure

  1. To pick the model that the layer will be based on, under Data Source select (edit).
    If you have associated a model with a previously added layer, this data source will by default appear under Data Source. Use (edit) to change the data source.
  2. Select Flow Layer from the Layer Type list.
  3. From the + Add Location Dimension list under Origin Location, select the dimension to serve as the starting point for the flow you want to visualize.
  4. From the + Add Location Dimension list under Destination Location, select the dimension to serve as the end point for the flow you want to visualize.
  5. Under Flow Color, select a measure from the + Add Measure list to associate values with the layer color on your map.
    1. Select a color for the flow arcs from the Palette list.
    2. If necessary, adjust the Opacity of the layer to ensure that the basemap or other layers are visible.
    3. Choose the number of Ranges for the palette.
      This sets the number of KPI values. Specify values to set the KPI ranges for each color in the palette. Use the switch beside the Ranges list to display KPI values as percentages or as absolute values.
  6. Under Flow Size, select a measure from the + Add Measure list to control the thickness of the flow arc.
    Use the Scale slider to adjust the size of flow arcs.
    Note
    A flow map layer is limited to 5000 flow arcs. The flow layer is included in the map legend. Any tooltips for the flow layer will indicate both the origin and destination dimension for a given data point.
  7. Select OK to save all layer settings.
