Damage in façades rendering is a problem that has been much discussed currently since such damage is important to the degradation process of building. There are many techniques to verify damages in façades and in other external parts of buildings; however, some tecniques have restrictions regarding their practical applications. This work deals with the application of the remote sensing (RM) technique. Such technique derives from the need to identify, locate and scale, quickly, accurately and without human risk, the existing damage or potential damages that may appear in the façades of buildings. Moreover, the RM technique may help to detect damages not visible at long distance or in location of difficult access. This technique is performed by corrected high-resolution panoramic images generated from a mosaic of pictures taken with a standard digital camera coupled in a robotic platform. The Itamaraty Palace, a government building, located in Brasília - DF (Brazil), is the object of the present study. The correction of the Itamaraty Palace panoramic image was carried out so that the identification, quantification and mapping of the Palace façade damages were performed using specific softwares such as GigaPan Stitch, AutoCAD and ArcGIS.
