The present article deals with the urbanization process in the Paraíba do Sul river basin, covering social occupation under consideration of the legal provisions for areas surrounding water resources. The study has the purpose of assessing the Environment Preservation Area, called APA Banhado, in the city of São José dos Campos, a municipality belonging to the Metropolitan Region of the Paraíba Valley and the Northern Sea Shore (RMVPLN) in the state of São Paulo, Brazil. The research carried out made use of materials and information collected from aerial images obtained from remote sensing databases maintained by public offices, and the provisions of the APA Banhado implementation law. In order to extract information from satellite images, the methodology proposed by Moreira (2011) was applied, which suggests an automatic software classification in the Geographical Information Systems (SIG), with visual interpretation. The maps generated from the classification of the APA Banhado were based on reference data from the years of 1995, 2000, 2005, 2010 and 2015. The results revealed conflicts between the environmental legislation and the land use, which prompted the possibility of generating basic data capable of incorporation into public planning policies and the preserved area environmental management, including a revision of concepts under the environmental preservation, as a future safety water reserve for the metropolitan region of the Paraíba Valley – SP. ; The present article deals with the urbanization process in the Paraíba do Sul river basin, covering social occupation under consideration of the legal provisions for areas surrounding water resources.

O estudo tem como objeto de avaliação a Área de Proteção Ambiental (APA) denominada Banhado, na cidade de São José dos Campos, município da Região Metropolitana do Vale do Paraíba e Litoral Norte (RMVPLN), São Paulo, Brasil. Para a realização da pesquisa foram utilizados materiais e informações de imagens aéreas, obtidas através de banco de dados de sensoriamento remoto de órgãos públicos, e as diretrizes da lei de implantação da APA do Banhado. Para a extração de informação das imagens de satélite, foi aplicada a metodologia proposta por Moreira (2011), que sugere uma classificação automática em software em ambiente de Sistemas de Informações Geográficas (SIG), com interpretação visual. Os mapas gerados de classificação da APA estadual do Banhado foram subsidiados por dados de referência ano 1995, 2000, 2005, 2010 e 2015. Os resultados obtidos são considerados conflitantes, entre a legislação ambiental e o uso do solo na área de estudo, propiciou a possibilidade de gerar subsídios passíveis de incorporação a políticas públicas de planejamento e gestão ambiental da área protegida, com a revisão de conceitos sob a ótica de preservação ambiental, como uma futura reserva de segurança hídrica, para a região metropolitana do Vale do Paraíba – SP.
