Land Cover and Usage in an Urban Drainage Basin Analyzed Through High Resolution Image Satellite

ABSTRACT

All classes of land cover and usage of an urban site have been mapped through ‘Quickbird’ image of 61 cm of space resolution for the study of a hydrologic basin. The objective of this study is to generate a detailed map of land cover and usage of the basin of “Arroio dos Pereiras” stream, located in Irati, State of Parana, Brazil, and also to quantify all the classes considered on the mapping. The acquired results will support other studies on possible flood occurrences in the central region of the city. The percentage results are as follows: 22.56% of forests, 0.22% of lagoons, 9.68% of paved streets and sidewalks, 4.84% of pervious area inside blocks, 5.73% of impervious area inside blocks, 10.53% of roofs and 46.45% of tripping vegetation.
