|NASA space shuttle data with a resolution of 30m. DTM coverage up to 60N||
|Global coverage up to 60N is provided by ALOS global digital surface model © JAXA. It was created in 2014 and has a resolution of 30m. |
|High altitude regions such as Greenland, Northern Norway and the Svalbard islands have been created at 90m resolution from mapping by Jonathan de Ferranti||http://viewfinderpanoramas.org/
|High resolution tiles mapped by plane and drone have resolutions ranging from 1-8m and are added for select areas. Currently England, Wales, Estonia, New York, Washington DC, Los Angeles, San Francisco, San Diego, Baltimore, Mogadishu, Tashkent||
