Land use and land cover mapping of Santa Catarina Island, Southern Brazil, using high-resolution aerial photography

Abstract

This paper presents a mapping of land use and land cover of Santa Catarina Island, in southern Brazil, based on high-resolution aerial photography and vectorization of aerophotogrammetric digital mapping at 1:2.000 scale produced by Urban Planning Institute of Florianopolis. The methodology adopted the visual analysis and interpretation of an aerial photogrammetric mosaic and the mapping method of land use patterns was organized into 17 classes. The results show the predominance of vegetation classes and urban areas. The patterns of urban areas are divided into continuous, discontinuous and diffuse categories, revealing punctual density and the presence of large urban areas only in the first settlements, real estate ventures or urban development projects.
