SUMMARY:

Geographic Information Systems (GIS) are systems used for monitoring, operation, analysis and planning. Recently, applications involving three-dimensional data have been gaining prominence, such as: 3D registration; urban planning; emergency response; prevention of seismic damage; floods, among others. Much research has been carried out on this topic with the aim of discussing elements related to geometric and semantic modeling according to the CityGML standard. In this standard it is necessary to define the Level of Detail (LOD), which indicates the elements and classes to be represented. Thus, this research proposes a 3D GIS application based on geometric and semantic modeling of the UFBA Federation/Ondina university campus, based on the CityGML standard, to optimize the use of spaces in order to assist campus management. For this, the Design Science Research (DSR) method was used, which seeks to build and evaluate artifacts based on a problem, seeking solutions for it. The methodology used involves: the acquisition of geometric data from the last official aerial photogrammetric survey of the municipality of Salvador, from 2017, to compose the geometric database of the study area; geometric and semantic modeling, in the CityGML standard, of the categories terrain, road system and buildings of the university campus using the SketchUp software and its CityEditor plugin; storing the resulting geometric model in the database as well as inserting new data and creating new tables according to the application's conceptual modeling (using the software PostgreSQL/PostGIS, PgAdmim and 3DCityDB); Finally, the feasibility of the 3D GIS application proposal is demonstrated based on consultations on the uses and functions of spaces as well as spatial analyzes that include the identification of possible routes (of the routes taken by students on campus) and evacuation routes, created to simulate areas susceptible to fire risk in some laboratories at the Polytechnic School.
