This work aims at making one brief contextualization on the state of the art of the geoprocessing in urban planning to present the new paradigms and challenges of the geo technologies related to the management of the cities. The visualization of planning process allowing the comprehensio
n of the possibilities contained in public landscape planning represents the main challenge faced by this research. Another important goal is to investigate how to overcome a paradigm related to a coded urban planning system communication that hinders community understanding and participation. This state of the art of the space production justifies the current studies in the geoprocessing for the development of tools, techniques and methodologies that meet the necessities to create interpretative pictures of the urban landscapes that facilitate the dialogue among the technician, the administrators and the community. The methodology was based on the cloud of points using Lidar techniques,3D modeling, tools of visualization and parametric modeling of urban parameters. In this direction, this work will point out the new trends of representation of the data and the decoding of the cartographic language from the geo visualizers within the values of interoperability, involvement of the actors,feedback and proposals from geo design.
