ABSTRACT


The spatial evolutions of anthropoid ecosystems and the space transformation in the course of time constitutes one of major concerns in the domain of environmental space management. The landscape evolution of a region area and the perspectives for a future state rises an issue particularly important. What will be the state of a region area in 15, 30 or 50 years? In fact, time consists of hierarchical events and can produce transformations over a terrain as appearance, disappearance or fusion of spatial entities... Those transformations are called temporal phenomena. We have developed a specific spatio-temporal forecasting approach. The idea we present here take a first step in attacking this problematic, it turns out very interesting results in this domain.

We describe in this approach a method for analysis and forecasting of a region area given a particularly date from n geographic maps which represent the state of the region area in different years. The basic idea is to employ the observation of the temporal phenomena evolution. In fact, results of this observation represent the evolution of each region area on maps in the course of time. The evolution modeling of the regions is obtained with the help of a sequence of aerial photographies compared through different dates. It allows the geographer interested in environmental prospective problems to get type cartographical documents showing the future conditions of a landscape.

The proposed method provides the potentiality of evolution or disappearing in region areas, by analyzing forestry progression and regression zones. Thus, sensitive factors on regions evolution are considered for the forecasting purpose. The results of this analysis is combined with out-image data that provide land area characteristics such as elevations, fire zones, distance to roads, distance to urban areas and expert knowledge.
