SUMMARY: NASA has released a new image of the entire Earth based on images taken during the Shuttle Radar Topography Mission. The global data set greatly improves maps of the Earth's surface between 60-degrees North and South of the equator - 80% of the globe. Previous maps of the United States have a similar resolution as the SRTM30 data - about 1 km - but the rest of the world is often inaccurate. SRTM is capable of producing even higher-resolution maps, down to 30 metres.
