| Sumario: | One of the most remarkable characteristics of the process of settlement in Latin America and Caribbean every greater time to the urbanization has been the tendency. This entailed obvious, to an acute concentration of the population, generating new urban systems to the interior of each country and even in the regions. In order to be able to understand and to evaluate the consequences of these processes it is necessary to investigate the changes of the use of the ground in great metropolitan areas; to evaluate the impacts of these changes in the ecosystems and regional resources; to apply technologies for the monitoreo, analysis and prediction of rates, patterns and impacts of changes of the land as a result of natural and human causes. Taking care of these necessities this investigation like integral part of a macro project was conceived which raised, as main training target to quantify and to delimit the growth of the region of the Great Mendoza, from the use of techniques of vl interpretation of satelite images LANDSAT TM of different dates under techniques from statistical and multitemporal analysis. The used methodology was based on the visual classification of the images, segmenting the areas of training in groups of pixels with certain related radiometric and statistical patterns to the type of consolidation of the urban uses. Later I correlate the result with the data validated in field and I analyze the space variation final present through a SIG. The quantification of the urban growth by this method showed an increase of 40%, equivalent to 9513 hectares, which traditionally demonstrate the strong tendency of the abandonment of areas agriculturists by new urban establishments, representing basically by an economic and educative distinguishing social class. |
