Collection scenarios (30° off-nadir angle):
- Long strip: 360 × 15,2 km
- Large Area Collect: 112 × 44 km
- Multiple Point Targets: 15,4 × 15,4 km
- Stereo Area Collect: 224 × 28 km
Benefits:
- Highly detailed imagery for mapping, change detection and in-depth image analysis;
- Geolocate features to less than 5 m to create maps in remote areas, maximizing the utility of available resources;
- Frequent update of imagery;
- Stereoscopic collection on a single pass provides image continuity and consistency of quality.
