The Brazilian gravimetric geoid: MAPGEO2010

Ana Cristina Oliveira Cancoro de Matos, Denizar Blitzkow, Gabriel do Nascimento Guimarães, Maria Cristina Barbosa Lobianco & Sonia Maria Alves Costa
The Brazilian geoid model MAPGEO2010 is limited by 6°N and 35°S in latitude and 30°W and 75°W in longitude with a 5' resolution. The terrestrial gravity data for the continent have been updated by surveys in Brazil and in the neighbour countries until 2010. The complete Bouguer and Helmert gravity anomalies have been derived through the Canadian package SHGEO. The short wavelength component was estimated via FFT. The geopotential model EGM2008 was used as a...
