Limit Map

Limit Map is a Setting that stores the Multi Polygon that will be used to limit the calculation of active Grid Overlays.

When this setting is configured with a non-empty Multi Polygon, the grid and TQL Queries are limited to a portion of the map. Limit map is always a rectangle bounding box of the Multi Polygon of the setting.

Calculation limited by a Areas, enveloped by a rectangular bounding box

To adjust this setting using the Tygron Client, see How to calculate only a part of the Project map.

Notes

• Only active Grid Overlays are affected by this setting
• When updating Grid Overlays only the box is updated and the rest contains NO_DATA values.
• Adding SKIP_NO_DATA=1 as an attribute to any Grid Overlay, keeps the orginal values in place. Note: This method allows for calculation larger then the GPU grid would allow by splitting the map up in Limit map boxes.
