What the Average overlay is

The Average overlay shows (smoothed) values of a grid cell. With the Average overlay it is possible to create a custom dynamic Grid overlay.

Purpose of the Average Overlay

A typical use-case of the Average Overlay is to display model data used in visualize parameters part of a simulation model (e.g. the rainfall overlay). A parameter assigned to a grid-cell can be related to one or more polygon layers. Such layers can be buildings, terrain, areas or neighborhoods.

Generating an Average Overlay:

Steps to generate an Average Overlay:

  • Go to the overlays tab, and select Add Avg
  • Step 1: Choose a selection type: If you wish to create a spatial smooting, press Create an average Grid Overlay, if you wish to Gain insight into Grid Cell Values, press the latter option
  • Step 2: Select an attribute value you wish to visualize: By pressing select you can select from a long list of attributes
  • Step 3: Select, Select Layer: Attributes can be assigned to one of more polygon data layers: buildings, Terrains, Areas and Neighborhoods. In this step you can select the following options for assigning parameter values:
  1. Filter occurrence in Layers: an attribute value is selected from order of occurrence in the polygon data layer value mentioned above
  2. Minimum values in Layers. The minimum value is selected from all layers above
  3. Maximum values in Layers. The maximum value is selected from all layers above
  4. Specific Layer only. A specific layer can be selected.
  • Step 4: Only when selected Create Grid Overlay in Step 1: a smoothing distance value

How to remove the Average overlay:
  1. Select in the editor 'Geo Data' from the ribbon
  2. Select 'Overlays' from the ribbon bar
  3. Select the desired overlay from the list of active overlays on the left panel
  4. Select 'remove' from the bottom of the left panel
  5. Confirm the removal in the pop up confirmation message
