Especificações técnicas de dados Geoespaciais para sistema de suporte à decisão do direito de uso de Recursos Hídricos no Estado da Bahia

Abstract

Geospatial data are increasingly frequent inputs in technical analysis for decision-making on granting the right to use water resources. Despite this, they are still not stored and structured in a Database Management System (DBMS) in order to integrate them into the Decision Support Systems (SSD) of these claims in the state of Bahia. This situation entails manual procedures, subjectivity in technical analysis, insecurity in the storage of geospatial data, lack of interaction between spatial and no spatial data and slowness in grant decision making. Given this scenario, the objective of the research is to propose a conceptual model of geospatial data in order to update the Decision Support System for granting the right to use water resources in the state of Bahia. To achieve this objective, the research consists of the following phases: identification of geospatial data (entities), relationships and respective attributes necessary for the technical analysis of granting the right to use water resources; elaboration of the Class Diagram, Transformation Diagram and Object Class Relations; and presentation of the technical specifications for structuring and acquiring vector geospatial data, through the manuals, ET EDGV/Outorga and ET-ADGV/Outorga. The results showed that both manuals can guide the standardization and systematization of geospatial data in DBMS, as well as take the first step towards integrating the SSD to grant the right to use water resources. In addition, the standardization advocated by these products facilitates the sharing, interoperability, security of geospatial data and the rationalization of resources between producing institutions and users of data and geospatial information granting the right to use water resources, promoting integration of water management.
