Elevation Measurements
For 39 years, based on an uncontested measurement performed in 1965 by topographer José Ambrósio de Miranda Pombo, using a theodolite, the elevation of Pico da Neblina was thought to be 3,014 metres (9,888 ft), but a much more accurate measurement performed in 2004 with state-of-the-art GPS equipment by cartographer Marco Aurélio de Almeida Lima, a member of a Brazilian army expedition, puts it at 2,994 m (9,823 ft). This is now recognised by the Brazilian Institute of Geography and Statistics (IBGE), the federal government's official geographic survey and census agency, which jointly organised the expedition.
