The objective of this research is to assess the multitemporal very high resolution single polarization SAR data for urban land cover/land-use mapping using a novel knowledge-based SEM algorithm. Three-date RADARSAT-2 ultra-fine beam SAR data were collected over the rural-urban fringe of Greater Toronto Area. A modified Stochastic Expectation-Maximization (SEM) algorithm which employs an adaptiv...

Developing realistic 3D models of cities provides designers, planners, the public, and the others with imagery closely coupled with the human expertise. This paper continues on the results of an earlier innovation in the field of texture creation for the construction of Virtually Realistic Model (VRM) of buildings in urban areas. Using a CCD camera mounted on a theodolite the system takes the i...

Statistical methods are usually applied in the processing of digital images for the analysis of the textures displayed by them. Aiming to evaluate the urbanization of a given location from satellite or aerial images, here we consider a simple processing to distinguish in them the “urban” from the “rural” texture. The method is based on the mean values and the standard deviations of the colour t...
