The Keller Peninsula (KP), on the King George Island, shelters the Brazilian Comandante Ferraz Station (EACF) and it has been the site from several international research projects. However, this area has not yet been mapped in detail, except for the area around the EACF, which is mapped at 1:500. Aiming to overcome the lack of a detailed and accurate map for the entire KP, this work proposes the use of photogrammetric and GIS techniques for the compilation of a new topographic map at a scale of 1:5,000. The elaboration of this map was based on interior and exterior orientation of aerial photographs, generation and edition of a Digital Terrain Model (DTM), derivation of contour lines from the created DTM and accuracy assessment of the results. Verification of horizontal position and elevation data of the resulting map showed a good correlation with data from other maps, mainly in the area around the EACF and at Flagstaff Hill.
