ABSTRACT
The study was conducted across the state of Espirito Santo, with the objective of limiting the Permanent Preservation Areas (PPAs) by optical law 12.651/2012 (forest code) and highlight the importance of identifying those areas automatically. Each PPA has its own methodology for their mapping, however, all were mapped with the aid of geotechnology. The state has 22.43% of its PPA area distributed along the marginal strip watercourses (10.42%); in the surroundings of lakes and natural ponds (0.67%); around the artificial water reservoirs (0.02%), in the vicinity of springs (0.89%) in the hillsides with slopes greater than 45° (0.24%); in restingas (1.92%); in mangroves (0.19%); on top of hills (8.98%); and in higher than 1800 meters (0.19%) of the total area of the state altitudes. This study serves as a technical subsidy for evaluation and quantification of PPAs in a State, since it is the first one in a state level in Brazil on the issue.
