Proposta metodológica para implantação de rede geodésica municipal integrando imagens de alta resolução espacial caso de estudo: Posto administrativo da Matola Sede

Abstract

The cadastral cartographic base of most Mozambican cities is deficient in several aspects, such as the lack of updating and the absence of a geodetic reference network. The administrative post of Matola headquarters, located in the city of Matola, fits this pattern, in which topographic surveys are referenced at arbitrary points, which do not belong to a unanimous and conventional reference system. Due to this deficiency and necessity, the objective of this work is to propose a methodology that integrates high spatial resolution images and satellite positioning techniques to optimize the process of implementing a cadastral geodetic network for the Matola Headquarters administrative post, focusing on the planning phase, where the quantity and location of vertices were defined through suitability analysis, based on geoprocessing and technical standard NBR 14.166, aiming to guarantee the stability, accessibility and intervisibility of the vertices. For this purpose, data on access roads, social equipment and infrastructures, soil types, water courses and land use and cover were used. With the results obtained, the geometric configuration of the Geodetic Network was defined, consisting of 18 vertices, with side lengths between 1 and 5 km, to be tracked using the Static Relative positioning technique, and the Observations should be adjusted later. This approach will become a tool to support Municipalities in identifying the technical and methodological procedures for implementing the municipal geodetic network, for better territorial management.(TRADUÇÃO NOSSA)
