From Pixels to 3D Representations of Buildings: A 3D Geo-visualization of Perspective Urban Respecting Some Urbanization Constraints

Résumé

In this paper, we generate the fictive 3D buildings and provide a 3D representation of an urban growth model using ArcGIS. SLEUTH urban growth model, like the other CA (Cellular Automata) models, creates a prospective 2D map containing some pixels on which urbanization is supposed to occur. These pixels have to be transformed into 3D building representations, while respecting some restrictions on urbanization. To create a building from a pixel, we transform the pixels from raster data to building footprints. In the process of transformation, different considerations and constraints are considered such as the direction of the footprints and the distances to urban objects and geographic features. To generate the 3D representations of the buildings, the appropriate heights are added to these footprints. The height of the buildings depends on the probability of the height of adjacent buildings. Although the provided 3D model is a primary and simple model, the 3D representation of the urb an growth allows having different images of the city of tomorrow for supporting the scientists and authorities in charge of urban planner and management.
