The U.S. Geological Survey (USGS) National Land Imaging Program (NLIP) is responsible for providing Earth science data to support scientific, operational, resource management, and other national needs. The USGS NLIP gathers details on the scientific and operational Earth observation sensor needs of users around the world and applies these metrics towards various Earth observation sensor and data development efforts. The USGS NLIP operates and provides data for the Landsat series of satellites and their 50-year data record of our changing planet.The Requirements, Capabilities, and Analysis for Earth Observation (RCA-EO) Project was established to understand and quantify Earth observation scientific and operational user needs. One of the missions of the RCA-EO Project is to identify and catalog existing and planned capabilities for measuring and monitoring the Earth. The RCA-EO Project also supports the Joint Agency Commercial Imagery Evaluation mission and has developed this compendium as one of the USGS contributions to the Joint Agency Commercial Imagery Evaluation effort.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
