Implantação de marco geodésico na Universidade Federal de Mato Grosso, Campus Universitário de Sinop

Abstract

At the end of 2022, the municipality of Sinop had one planimetric station only, which is integrated in the Brazilian Geodetic System (SGB). Once this kind of spatial infrastructure is very important to support different types of mapping projects, land regularization, land subdivision, infrastructure projects, among others, this work aimed to implement another planimetric station, localizated at the Federal University of Mato Grosso, in the University Campus of Sinop, and subsequent data submission for approval process at the Brazilian Institute of Geography and Statistics (IBGE) and the inclusion in the Brazilian Geodetic System. It was performed all the required steps in accordance with IBGE normative instruction, from the analysis of potential sites for the geodesic landmark installation, to its construction procedure. The data processing was performed using two post-processing methods: static relative positioning and precise point positioning (PPP) with the online service provided by the IBGE. The calculated coordinates acquired results of standard deviation in centimetric order (for the relative static method) and millimetric order (for the PPP method), whereas the lower results are related to the big distances between available stations of the Brazilian Network of Continuous Monitoring (RBMC) at the time. Finally, the present work resulted in the execution of all the steps and generation of the necessary information for approval process of the geodesic mark, being under analysis phase by the IBGE.
