Globe Overlays

Globe Overlays are used to render and organize terrain and imagery on a globe. Overlays can be turned on/off based on the camera's altitude or current animation time using Display Conditions. JPEG 2000 (.jp2), AGI's Processed Image format (.pdttx), and AGI's Roam Image format (.txm) are supported. For terrain, AGI's Processed Terrain format (.pdtt) is supported. Interfaces exist to programmatically create PDTT and JP2 files.

Overlays are in the agi.foundation.graphics package.
