Modelagem conceitual de dados geoespaciais: uma aplicação na saúde coletiva com ênfase em epidemiologia.

Abstract

This work aims to develop a conceptual model of geospatial data applied to the Sanitary Interventions and Urban Leptospirosis Prevention Project, which carries out its activities in urban communities of Salvador (BA). It addresses the challenges arising from the absence of a geographic database, such as lack of standardization, data duplication, versioning issues, and limited traceability. Considering that the requirements gathering and analysis phase precedes conceptual modeling, a questionnaire was applied to the main producers and users of the project's geospatial data, through which needs, data types, attributes, and spatial relationships were identified. Based on this, a conceptual model was developed using the object-oriented OMT-G approach, and represented with the online tool OMT-G Designer. The resulting class diagram is centered on the spatial unit "block", which guides the data collection activities of the project. It is concluded that conceptual modeling can significantly contribute to the systematization of the project's geospatial data, enabling the development of a logical model and, subsequently, the implementation of a geographic database. This process is essential for strengthening data governance and facilitating the development of applications aimed at data dissemination and analysis, with the goal of supporting strategic actions, especially in the field of public health.
