Implantação e planejamento de marcos geodésicos para georreferenciamento e levantamento cadastral na Universidade Federal de Sergipe – Campus São Cristóvão

Abstract

This work presents the results of the implementation of a network of geodetic landmarks for georeferencing and cadastral survey on the São Cristóvão Campus of the Federal University of Sergipe (UFS). With the aim of providing an accurate reference base for academic and professional use, 13 strategic landmarks were installed using dual-frequency geodetic GNSS (L1 and L2), with Comnav T300 and T30 receivers. The relative and static positioning technique was applied to track coordinates, and data processing was done with the Compass Solution software. The methodology applied guaranteed the accuracy of the coordinates in the UTM projection system, using the SIRGAS 2000 data. The results show that geodetic landmarks have a low RMS factor and adequate PDOP, HDOP and VDOP values, providing high quality of the obtained coordinates. With the completion of this project, UFS now has its own high-quality geodetic base, useful for future research and applications in engineering, urban planning and other areas that depend on georeferenced data.
