This paper intends to be a brief contextualization about the state-of-the-art on the use of Geoprocessing on urban planning in order to present new paradigms and challenges on the use of geotecnologies focused on cities' management. Such state-of-the-art of space production justifies the current studies on geoprocessing towards the developing of tools, techniques, and methodologies which can serve the necessities of the creation of interpretative pictures of urban landscapes that may ease the dialogue among technicians, administrative workers, and the community. In this sense, this paper will show new trends, paradigms and challenges in the threedimensional models for cities representation.
