Object: The present researchtakes advantage of wide spreadtechnologies such as GPS, VHF telecommunications, field sensors and techniques commonly used in telegeoprocessing and teleomonitoring procedures in order to remotely model and simulate an existing urban or architectural environment with its spatial properties such as sound, temperature, humidity, etc. It also presents and compares adequate systems using almost similar technologies which contribute to a remote spatial urban simulation. Methods: This research describes a method process of a remote system that captures and transmits spatial data collected from the real urban or architectural environment directly, in real-time, into a CAD 3D modeling and simulation environment. These spatial data are manipulated adequately via specially developed interfaces in order to be simulated simultaneously in superposed layers cartography. Results: The remote feed of CAD software with spatial data provokes the drawing of new 3D real entities in architectural scale (rooms, squares, buildings position, roads, etc.), or in urban scale (relief, morphology, etc.) in real-time, as the field-user handles a peripheral device of the modelling software (which is connected wirelessly), creating automatically a superposed cartography of spatial properties (sound pressure level, intensity, noise, temperature, etc.). This methodology was applied to the Diachronic Museum of Larissa ? Greece by creating a relief of its surround area, its buildings positions and a superposed sound pressure level cartography. Conclusions: Each entity, which is created in real-time, can directly participate in any spatial analysis operation without further treatment.The space and its properties simulationcan constitute a common base of holistic description of space with hugepossibilitiesofdevelopmentandapplications.
