资源简介：
High resolution photographs and video can be acquired in areas of the United States that were previously too expensive or too dangerous to monitor. Additional geospatial products can be generated from the raw data to meet the needs of the scientific research and public safety communities. Derived products include orthophotographs, point cloud data, and Digital Elevation Models (DEM). Support documents for UAS projects are also available.
