USE OF TECHNIQUES OF REMOTE SENSING IN THE ENVIRONMENTAL DIAGNOSIS OF THE ESTUARY ACARAÚ RIVER - CEARÁ - BRAZIL

Abstract

The Acaraú basin is located to west of the capital from Ceará and it understands an area of 14.500Km² being considered the second largest Ceará basin. The area the research understood the area estuary of the Acaraú river 80Km², embracing the munipality of Acaraú and Cruz in the west. The research has for objectives to analyze the geo- environmental conditions, to analyze the use process and occupation and the environmental impacts, as well as to take an understanding to the resident population in the area and of conserving the resources of nature in maintainable way to guarantee for the next generations. As methodology were used pertinent bibliographies to the subject, pictures and of satellites images and with good resolution as the images of Quickbird. The geo-processing activities involved images digital processing of remote sensing and the integration of data in structure of SIG (System of Geographical Information). The obtained results consisted in the integrated environmental analysis generating a proposal of environmental zoning. Keywords: Environmental analysis, mangroves, estuary.
