CHARACTERIZATION GEOENVIRONMENTAL BASIN URBAN STREAM ROSEIRA - LONDRINA / PR USING GEOGRAPHIC INFORMATION SYSTEM (GIS)

Londrina has in its urban area, approximately 84 watercourses, due to this, there is a great need for environmental planning that considers the physical and land use in a watershed, thus providing a diagnosis of condition and quality of environmental city. In this sense, we carried out a survey of the physical characteristics of the basin Stream Roseira using the software SPRING 4.3 and QuickBird satellite imagery and techniques from the GIS was created a database environment in which it was possible to use map creation soil of Permanent Preservation Area, and hypsometric slope. Through data analysis and site visits were observed that environmental laws and land subdivision laws are not being met, such as irregular occupations within the APP, lack of riparian vegetation, improper use and occupation of land beyond the incorrect allocation residues.
