The advance of urbanization has caused substantial transformations in the social and morphological aspects of coastal areas. The present study aims at modeling data from several sources, such as GNSS (Global Navigation Satellite Systems), and remote sensing and subsequently to provide the spacialization of coastal vulnerability to erosion, by using fuzzy logic. In the applied method for vulnerability analysis, linguistic variables, fuzzy partitions, intervals and parametric analysis that characterize fuzzy modeling were used. After analyzing the levels of vulnerability to coastal erosion along the shoreline in the cities of Recife and Jaboatão dos Guararapes at the coast of Pernambuco, the following results were achieved: 33.33% of the coastline has low vulnerability while, 38.15% moderate vulnerability, 14.26% high vulnerability and, 14.26% very high vulnerability.
