- THE COMPUTATION OF THE GEOID MODEL IN THE STATE OF SÃO PAULO USING TWO METHODOLOGIES AND GOCE MODELS GABRIEL DO NASCIMENTO GUIMARÃES DENIZAR BLITZKOW RICCARDO BARZAGHI ANA CRISTINA OLIVEIRA CANCORO DE MATOS Ciencias de la Tierra Geodesy Gravity Geoid Model GOCE Mission The purpose of this manuscript is to compute and to evaluate the geoid model in the State of São Paulo from two methodologies (Stokes’ integral through the Fast Fourier Transform - FFT and Least Squares Collocati on – LSC). Another objective of this study is to verify the potentiality of GOCE -based. A special attention is given to GOCE mission. The theory related to Stokes’ inte gral and Least Squares Collocation is also discussed in this work. The spe ctral decomposition was employed in the geoid models computation and the lo ng wavelength component was represented by EGM2008 up to degree and order 150 a nd 360 and GOCE-based models up to 150. The models were compared in terms of geoid height residual and absolute and relative comparisons from GPS/leveling and the results show consistency between them. In addition, a comparison in the mountain regions was carried out to verify the methodologies behavior in this area; the results showed that LSC is less consistent than FFT. 2014 artículo científico 1413-4853 https://www.redalyc.org/articulo.oa?id=393933924012 en http://www.redalyc.org/revista.oa?id=3939 Boletim de Ciências Geodésicas application/pdf Universidade Federal do Paraná Boletim de Ciências Geodésicas (Brasil) Num.1 Vol.20
