                         along the coastal region of Rio Grande do Sul through the spectral 
                         classification of satellite images of the Hyperion sensor. As a 
                         contribution, it demonstrates the possibility of building mineral 
                         mapping using satellite datafor coastal areas without vegetation 
                         cover. The methodology steps were: 1) bibliographic review to 
                         determine concentration values typical of the mineral of interest 
                         2) selecting from a spectral library of signatures minerals of 
                         interest; 3) determination of the features characteristic for 
                         minerals of interest, generating endmember files; 4) obtaining and 
                         pre-processing of hyperspectral data from Hyperion to the study 
                         area; 5) reducing the dimensionality of the hyperspectral data 
                         analyzed in order to avoid redundancy and excess processing; 6) 
                         comparing the selected and endmembers this spectral response for 
                         each pixel of the image by using the spectral comparison technique 
                         known as first-derivative; 7) determination of the presence of 
                         minerals of titanium maps for the analyzed area; and 8) comparison 
                         between the results and those described in the literature. From 
                         this method, they built up thematic images indicating the presumed 
                         presence mineral per pixel, represented in scale concentration. 
                         The work exposed the use of orbital sensor data as an important 
                         mining support tool as well as the mapping of mineral resources 
                         over large areas.",
