Description
Two optical satellites, Pleiades 1A and 1B, provide high-resolution Earth observation data from a 694 km Sun-synchronous orbit. The system offers a native spatial resolution of 0.7 meters at nadir, a 20 km field of view, and a revisit time of less than 24 hours for global daily access. CNES, the French space agency, created this program as part of its Earth observation strategy, with data described as of March 25, —.
Use Cases
Create detailed land cover and land use maps based on the 0.7-meter spatial resolution.
Monitor infrastructure development or change detection based on the daily global access capability.
Generate 3D terrain models and digital elevation maps based on the stereoscopic acquisition capacity.
Support disaster response and assessment based on the high acquisition capability and agility.
Strengths
Provides very high spatial resolution of 0.7 meters at nadir.
Offers a high acquisition capability with a revisit time lower than 24 hours for daily global access.
Satellite constellation provides stereoscopic acquisition capacity for 3D analysis.
