About

Coincident Data Discovery platform allows users to search for data from multiple sources that intersect with a user-defined polygon. The tool currently supports PlanetScope, Landsat, and Sentinel data sources. The user can specify the maximum time range and cloud cover. The tool also allows users to search for intersections between two polygons in the data.
