Abstract
Aerodromes protection zones are defined by plans that are determined by three-dimensional (3D) limiting surfaces, which establish the airspace that must remain clear of obstacles, imposing some restrictions on land use. The objective of this paper is to generate 3D models of the surrounding area of Salgado Filho International Airport, considering the constructive altimetric limit established in the Aerodrome Protection Zone Basic Plan (PBZPA), to identify and quantify obstacles related to plots (urban land parcels) and buildings. The adopted methodology includes the analysis and selection of geospatial data, data modeling and performing spatial analysis on the generated 3D models. The results showed that out of a total of 106,838 plots, covering an area of 69.68 km², 4,826 plots (4.52%) exceeded the limiting surface and 1,054 plots (0.99%) represent critical areas where constructions may not be allowed. And, out of a total of 200,573 buildings, 26,418 of them (13.17%) exceeded the limit imposed by PBZPA’s. Also, the methodology is valid for detecting and quantifying critical areas concerning the constructive viability of the plots, affected areas regarding the height of the plots and buildings, and for identifying obstacles to aerodromes according to their respective airspace laws.
Highlights
Mapping of aerodrome protection zones is necessary for urban planning and the economy of cities, as well as for the safety of the population living there

The results of the spatial analysis allowed us to identify and quantify the obstacles in the Salgado Filho Airport airspace, based on the constraints established by PBZPA limiting surfaces
Summary
Mapping of aerodrome protection zones is necessary for urban planning and the economy of cities, as well as for the safety of the population living there. The set of three-dimensional (3D) imaginary surfaces established by the Aerodrome Protection Zone Basic Plan (PBZPA) delimits and establishes the airspace that must remain clear of obstacles, imposing restrictions on the land use within the aerodrome protection zone. These imaginary surfaces set the boundaries that objects can project into airspace without adversely affecting the safety and regularity of air operations (Brasil, 2015). This issue can be assessed through spatial analysis that allows the visualization and detection of critical and obstructed areas, serving as a basis for decisions regarding the management of land use and occupation around the aerodrome
