Mjerenje duljina i površina u Google Mapsu i Google Earthu

In 2005, Google Maps was launched on the internet as a service intended to aid orientation in space and navigation from one point to another by car, public transport, on foot, by bicycle, or by plane. In making the mathematical basis of the maps, Google Maps applied a procedure in which geodetic coordinates on the ellipsoid φ and λ were mapped into a plane according to the formulas of the normal Mercator projection for mapping a sphere.Google je 2005. godine pokrenuo na internetu Google Maps, uslugu namijenjenu snalaženju u prostoru i kretanju od jedne točke do druge automobilom, javnim prijevozom, pješice, biciklom ili zrakoplovom. Pritom je u izradi matematičke osnove karata primijenio postupak u kojem su geodetske koordinate na elipsoidu φ i λ preslikane u ravninu po formulama uspravne Mercatorove projekcije za preslikavanje sfe­re
