IDENTIFICAÇÃO DE FEIÇÕES MORFOLÓGICAS COM SIGNIFICADO GEOLÓGICO UTILIZANDO FILMAGENS AÉREAS EM PERSPECTIVA, A BAIXAS ALTITUDES

Abstract

The utilization of filming in low altitudes allows an approach of the constituent elements of the landscape and the identification of morphological homogeneous zones with geological meaning. The cover of areas through "non Nadir" filming allows users to visualize the drainage patterns and elements of relief that complement the visualization offered by the satellites images, aerial photos, digital terrain models, thematic maps and field phases, according to the sight of an observer through airplane window. The dynamic obtained with the filming offers the possibility to perceive features in a complete and broader context, showing more details than those obtained in static scenes, despite it can be worked in a continuous way in varied scales with digital images. In the area focused in this text, situated between the cities of “Rio Claro” and “Piracicaba”, there are areas where the morphological pattern has tectonic meaning, related to tectonic activities and faults, which conditioned the rising and the evolution of the structural feature of Pitanga. The filmings, made with portable digital camera, occurred between the years of 2003 and 2006 from flights in altitudes that varied between 100 and 1500 meters from the soil.
