Limit Map

This article is a stub. The following information should be added:

• where is this setting in the UI.
• what kind of Item is it
• what happens when set based on a different Item (are changes reflected or not)
• Affects all grid overlays
• what about X queries of TQL for items outside limit map
• Document SKIP_NO_DATA on separate appropriate page.
• how to page for splitting up calculation

When this setting is active the grid and TQL Queries are limited to a portion of the map. Limit map is always a rectangle bounding box shape.

• 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.
