Initially, the land use and the land occupation were evaluated, being delimited the municipal hydrographical micro basin and the permanent preservation areas (PPAs). For this purpose, multispectral images of high spatial resolution were used, available by the government partnerships between the City Hall, the state and federal authorities. From the obtained results it was possible to efficiently determine that only 3% of the original vegetation is preserved; the livestock is the main municipal occupation, covering more than 41% of the area; citrus and sugar-cane are also very expressive, occupying, respectively 13% and 7% of the area of the municipality of Vitoria; and around 70% of the municipal PPAs need hydrophilic species for its recovering.
