Integração Aerogeofísica E Imagens De Satélite: Folhas Três Rios, Anta, Duas Barras, Itaipava Teresópolis E Nova Friburgo - Estado Do Rio De Janeiro

In order to answer some questions about<br>geological situations in Rio de Janeiro State, we<br>wave used a combination of geophysical and<br>image processing techniques. These techniques<br>involved the joint processing, integration and<br>interpretation of Landsat image and aeromagnetic<br>gamaespectrometric data.<br>We have applied geometric and<br>atmospheric corrections, followed by band<br>rationing, principal component analysis and<br>spacial frequency filtering. The processed images<br>were integrated with geophysical data by applying<br>the combination (RGB) and fusion (IHS) techniques.<br>The interpretation of the integrated<br>images contributed to geologic knowledge of the<br>redefine importants structures in State of Rio de Janeiro.
