The geography of these results has been briefly analysed. A theoretic reference is formalised and then compared with local realities in order to appreciate recurring and specific elements. In spite of differences due to geographic and urban locations and to the role of huertas, the principles of spatial organisation follow the same rules. A NOAA 11 meteorological satellite image enables one to observe the distribution of the main regional landscapes as defined by radiometry. Landscapes here defined are chiefly related to the main physiographic areas.
Ombrothermal diagrams are a representation of the climate from a naturalistic point of view.
Mid-latitude and more precisely mediterranean climates are considered as the reference for the comparison of the world's climates. The gridmap of Rouen and its suburbs makes computer mapping of socio-demographic data concerning the entire city possible. Two cartographical methods were used on this gridmap providing a new perception of the information and improved representation. The comparison between mental images of a given urban area can help to think about exclusion.
