Le lieu objet urbain, une singularité morphogénétique ?

Abstract : Images which are broadcast by satellite represent electromagnetic impulses matrices of the geographic space portions: pixels. These representations are neither the geographic objects themselves, nor their direct "reflections" under the thoughtful shape of brilliance accompanied with a sensation of colour. They are representations of electromagnetic impulses resulting from object recognition. These are localized on the screen by means of a geodesic coordinate systems. On the screen, one sees localized differences between "images". These differences are considered as geographic because they are localized in the surface of the Earth. But is the localization sufficient to justify the "geographic" qualifier term? The question arises as far as several objects can be localized in the same localization. The geographic character does not so like localization but the geographic differentiation. In the case of the geographic space morphogenetic modeling method one observes images of objects the "reflections" are combined. Or more exactly, differences between images of objects which most of the time are not simple but not combined among them and for whom, i.e. the urbanized zones are chaotic singularities. The morph-genetic method does not lean only on the geodesic differentiation of the localizations but also on the geographic differentiation of objects. All objects are considered as having a locus in the surface of the Earth. This method recognizes at first locus localized before the localized objects, that is for which it tries to represent the geographic locus-objects.
