Levantamento Geodésico do Campus Monte Carmelo da Universidade Federal de Uberlândia

Abstract

This study aims to survey the area of the Federal University of Uberlândia (UFU) Campus Monte Carmelo - MG, basing on current regulations in INCRA (Positioning Technical Manual, Borders and Confrontations and aspects of precision). The geodetic survey methodology adopted in this work with the use of manuals and specific legislation for rural properties is due to the fact that currently, there is no exclusive legislation for urban real estate and the property bordering are in rural areas, so need for an approach to rural concepts. The GNSS survey was conducted from two base stations adopting the positioning method Relative Static Fast. In all, 75 were screened vertices. All points raised showed a satisfactory precision to meet the precise conditions required in geocoding services of rural land by INCRA of 0.50 m. Only one point presented planimetric accuracy worse than 0.01 m and 6 other points precisely between 0.005 m and 0.008m. The resulting planimetric 95% of the remaining points remained below 0.005 m. Another parameter analyzed are the values of the areas 1, 2, 3 and 4 (Area 1 – area calculated in SGL; Area 2: area calculated via GNSS survey with reference to the SGB; Area 3: Calculated area from registration coordinates 2016; and area 4: area value described in enrollment). Areas 1 and 2 were calculated from the coordinates obtained in the field, while areas 3 and 4 arising from property registration information. The results of areas (1, 2 and 3) showed equivalent, but the value of the area 4 showed a value well above the areas (1, 2 and 3). The difference of the value of the area 4 with the average areas (1, 2 and 3) is 0.4619 hectare (ha), representing 1.98% of the area 4.
