Request an efficient handling of large ground zones visibility from an onboard FoV
Currently, OreKit lacks a way to efficiently determine the visibility of an on-board FoV with a large ground area. The FootprintOverlapDetector
provides some of this capability, but has limitations when dealing with large areas (e.g. country-, continent- sized). The GeographicRegionDetector
handles larger areas, but doesn't account for the onboard FieldOfView.
An example use case could be:
- a landsat-sized, nadir-pointing FoV
- Country borders loaded from https://www.naturalearthdata.com/ (e.g. https://www.naturalearthdata.com/http//www.naturalearthdata.com/download/110m/cultural/110m_cultural.zip)
- From a LEO orbit (e.g. landsat), compute FoV intersections with various countries over a several day timespan.
