What are the sources for satellite photographs of landscape?
Sources of Open Data
- Corona Atlas of the Middle East (select orthorectified CORONA imagery)
- The U.S. Geological Survey's Earth Resources Observation and Science (EROS) Center provides a variety of geospatial data products (including aerial and satellite imagery), many not limited to North America. These are summarized, with links to their various dissemination systems, on the EROS Products and Data Available page. Available imagery includes: CORONA, Landsat.
- Open Map Tiles (both free and commercial versions of data, hosting, etc.)

Other programs and websites
Other than Google Earth, which has good street-level images of most built-up areas, the sources known to us are:
- NASA's World Wind (free, mostly comparable in resolution to Google. Will be suspended from April 5, 2019. SDKs downloadable from Github.)
- DigitalGlobe/QuickBird (commercial)
- Zoom Earth – (daily satellite images: "In some cases the imagery is such high quality (often far better than Google Earth) that it's possible to pick out forest disturbance indicators from ancient human action via visual inspection of the imagery alone.")
- MapTiler (both free and licensed versions of mappign service; uses OpenMapTiles)
