Top high-resolution satellite imagery providers

Commercial data in use

Satellite images are only as good as their resolution. The smaller the pixel size, the sharper the image. High-resolution satellite imagery tracks the changing human footprint across the globe, including rapidly growing cities, urban sprawl, and informal settlements. It also serves the basis for a global effort to map the world’s communities, such as OpenStreetMap, a platform where the imagery is used to digitize maps.
