The delimitation of geoenvironmental units enables knowledge of the potential and limitations of the studied physical environment, through the integration of the constituent components of the landscape, pointing out guidelines that minimize and / or avoid negative environmental impacts, subsidizing environmental planning. The objective of this research is to carry out the mapping of the Geoenvironmental Units of the Atalaia Island located in the municipality of Salinópolis PA. This island was chosen because of the significant socio-environmental changes that are currently taking place in this area, which makes it possible to perceive the negative impacts, especially in vulnerable environments, where there are contrasts in the way of using and occupying land, in urban expansion, in agricultural activities and in tourist intensification. In order to arrive at the result of the research, bibliographic surveys, Geoprocessing and remote sensing techniques were used, analysis of satellite images, fieldwork, necessary for the observation in locus and the crossing of the information obtained, which resulted in the map of Geoenvironmental Units. In this way, it was obtained the definition of four homogeneous units according to the potentialities and limitations to the processes of the physical environment and the indiscriminate use of these environments. These units were found from information on secondary materials, essential for the elaboration of the Geoenvironmental zoning proposal of the study area, which serves as a contribution in the elaboration of future plans, as well as for the purposes of rational exploration of natural resources and sustainable use in Atalaia island.
