Uso de geotecnologias para identificação de diferentes padrões de ocupação urbana da bacia hidrográfica do rio Cará-Cará – Ponta Grossa-PR

Abstract

Urban areas are very diverse in relation to the standard practices of space use, what produces specific characteristics in each portion of space. The environmental analyses when involve urban areas may have difficulties to identify and represent these differences. This present work devises a method, based on photointerpretation, which evaluates determined spatial variables, taking as its starting point the creation and superposition of a rectangular grid over an aerophotogrametric mosaic, which serves as an instrument for the representation of the analysis. For each point of the grid, values are defined from the considered variables, which are lately interpolated, resulting into a division of five classes, which represent different standard practices of urban occupation. The method proved to be efficient because it achieved its objectives and, moreover, it showed to be less expensive and of easy execution.
