GEOGRAPHIC INFORMATION SYSTEM FOR 3D MODELING OF THE SPECIFIC AIRPORT PROTECTION XONE PLAN AND URBAN PLANNING PROTECTION ZONE PLAN AND URBAN PLANNING

摘要

This paper presents a Geographical Information System (GIS) developed for zoning of land use and its occupation, in terms of the gauge or height of buildings, defined by the Municipal Master Plan Design for Environmental and Development (PDDUA) in an area surrounding Salgado Filho Interational Airport, city of Porto Alegre, Rio Grande do Sul State, south of Braizil. The analyses takes information from the terrain elevation, the Airport's Safety Zoning Specific Plan (PEZPA) applied to his region and the urban land parceling in the area of study. This work aims at providing a tool for decision making supprot in urban planning, at cadastral level, in order to map and analyzes constructive feasibility considering its altimetric aspect taking into account the above elements. The implementation of this GIS together with its methodology highly contributes to contemportary society as far as it permits quick analysis of technical feasibility of constructive projects or infrastructure projects, either public or private, in compliance with recommendations given by PEZPA and by PDDUA. For this purpose we developed products from graphic and non-graphic pre-existing information and also from new information especially generated for this work. Results together with generated products enable the achievement of the proposed analysis and uncover new possibilities for improving Geographical Information System.
