Procedimentos para estruturação de dados geoespaciais como suporte a gestão da bacia hidrográfica dos afluentes do rio Mucuri-MG.

With the emerging need for proper management of water resources, the River Basin Committees (CBH), instructed by the National and State Water Resources Policies, Agency. The Water Resources Plan, classification of bodies of water into classes, according to predominant uses, granting of the right to use water resources, charging the aforementioned management instruments. Aiming at more agility in responses and greater effectiveness in decision-making, it is essential that geospatial data be organized in a systematized way and the development of Spatial Data Infrastructure (SDI) is one of the most complete forms of data systematization. It aims to standardize appropriate forms of generation, storage, sharing, dissemination, and use of geospatial data, thus avoiding the waste of public resources. The River Basin of the Velhas River (SF5) was used as a reference, which has four of the five management instruments implemented, and its Basin (Live Fish Agency) was established, and the River Basin of the Mineiros Affluents of the Mucuri River was the application area. of supporting the development of an SDI for water management, the data inventory used for the creation of the Conceptual Model of Geospatial Data was built, developed through the object-oriented modeling technique, used to describe the structure, systematize the understanding of objects and phenomena that will be represented in a computerized environment and database operations. The Technical Specifications for the Acquisition and Structuring of Geospatial Vector Data are created from the Conceptual Data Model, known as ET-ADGV and ET-EDGV, respectively. These Technical Specifications are organized by categories that present and detail each of the object classes with the name, description, and geometric primitive, and relate and detail the data attributes. They also present tables with code lists for attributes that have predefined domain relations. The ET-ADGV guide the process of building geometries to represent elements necessary for the management of water resources. The creation of these documents is seen as a fundamental procedure for structuring and systematizing your information, defined as necessary regulations for joining the National Spatial Data Infrastructure (INDE) and allowing the interoperability of geospatial data and information. The results of this project provide CBH MU1 with tools that guided it in the process of acquiring geospatial data inherent to the management instruments and river basin committees referring to the procedures for developing Spatial Data Infrastructures supporting the management of water resources.
