Global 1-kilometer Map
This map is derived from GTOPO30 data that describes the elevation of Earth's terrain at intervals of 30 arcseconds (approximately 1 km). It uses color and shading instead of contour lines to indicate elevation.
| Each tile is available at a resolution of 1800 × 1800 pixels (approximate file size 1 MB, 60 pixels = 1 degree, 1 pixel = 1 minute) | |||||||||||

Famous quotes containing the words global and/or map:
“Much of what Mr. Wallace calls his global thinking is, no matter how you slice it, still “globaloney.” Mr. Wallace’s warp of sense and his woof of nonsense is very tricky cloth out of which to cut the pattern of a post-war world.”
—Clare Boothe Luce (1903–1987)
“A map of the world that does not include Utopia is not worth even glancing at, for it leaves out the one country at which Humanity is always landing.”
—Oscar Wilde (1854–1900)
