Systems and methods for earth observation
Systems and methods are provided for obtaining and managing remote sensing data (e.g. Earth observation data). A remote sensing platform obtains imagery and other remote sensing data of the Earth and other planetary objects. The remote sensing platform includes the International Space Station, or manned and unmanned spacecraft or aircraft. A sensor captures observation data and transmits the data to ground stations on the Earth. A ground segment receives and stores the data. Users use an order management system to place orders for the observation data, which specify processing parameters for the remote sensing data. The remote sensing data is retrieved from storage is processed according to the parameters to generate a data product. This system provides tools for searching and analyzing the data, and for interacting with the system through an API. The system combines data that is produced by the remote sensing platform and by third parties.

9. The system of claim 1 wherein the requested geospatial information is provided to the requester in a form of a presentation of at least one thumbnail image from the retrieved one or more sets of data.
10. The system of claim 1 wherein the requested geospatial information is provided to the requester in a form of an export of the retrieved one or more sets of data.
11. The system of claim 1 wherein the Web interface is at least one of an application programming interface or a Web-based graphical user interface.
12. A method of distributing geospatial information via a Web-based platform which comprises at least one processor and at least one nontransitory processor-readable medium communicatively coupled to the at least one processor and which stores at least one of processor-executable instructions or data, the method comprising:
