GridSpatial

Activated measure with a GridSpatial and several buildings on top.

A GridSpatial is a component of a Measure that stores spatial information on how to apply a set of Grids to the DTM when the measure is activated. The area to which the Grids are applied can be restricted by specifying a MultiPolygon to the GridSpatial.

This MultiPolygon can either be:

• Calculated automatically based on the configured Grids for that GridSpatial.
• Configured manually by supplying a MultiPolygon, for example by drawing or importing.

Notes

• You can add more than one Grid to a GridSpatial of a Measure.
• You can manually provide a MultiPolygon to specify where the Grids are applied.
• GridSpatials are applied in the order at which they were added to a Measure. Similarly, Grids of a GridSpatial are applied in the order at which they were added to the GridSpatial.
• No data values in a Grid are never applied to the DTM.
• The specified Grid Overlays must be set to inactive, otherwise the Measure cannot be applied.
