This work aimed to describe and practically apply the technical procedure of georeferencing a rural property, covering all stages of the process, from the field survey to the certification of the geometry in the Land Management System (SIGEF) and the preparation of the technical documents necessary for the rectification of the property registration. The survey was carried out using GNSS receivers, with the determination of the coordinates of a base station at the property location through the IBGE-PPP service and the vertices with the real-time kinematic relative positioning method (RTK), ensuring precision compatible with that required by law. The data were processed and submitted to SIGEF, where certification confirmed the geometric consistency and the absence of overlaps. Finally, the plan and descriptive report were prepared, essential documents to guide the administrative procedure at the Land Registry Office. The results demonstrate the efficiency of the adopted methodological flow and highlight the importance of integrating geodetic techniques, geoprocessing tools, and legal norms for rural real estate regularization. The study reinforces the relevance of georeferencing as an instrument of territorial planning and registration security.

The municipality of Uberlândia (MG), located in the Triângulo Mineiro region, has undergone a major territorial transformation process since the 1980s, due to the continuous expansion of agriculture and the urban area. Therefore, the general objective of this work was to analyze the spatial evolution of Land Use and Land Cover in the municipality between 1985 and 2024, in order to evaluate the transformations and identify the main changes. The methodology used in the multitemporal analysis of remote sensing data, with images and maps from the MapBiomas platform - Collection 10 for the years 1985, 1995, 2005, 2015, and 2024. To ensure consistency between the statistical information, the Constant Total Area Normalization method was applied, using the Official Territorial Area of the municipality of Uberlândia, which according to the IBGE is 411,520.60 hectares, as a fixed reference for the percentage calculation of each class. The processing and calculations of the areas were performed using QGIS and Microsoft Excel software. The results indicate significant changes in Land Use and Land Cover in Uberlândia between 1985 and 2024, with a reduction in the natural formations of the Cerrado Biome and an expansion of anthropogenic activities. Pastureland was predominant in the early decades, while from the 2000s onwards, there was an intensification of agriculture, especially with the expansion of soybean and temporary crops. The urbanized area showed continuous growth throughout the period, highlighting the dynamics of territorial transformation associated with the economic development and population growth of the municipality.

Geodetic networks are widely applied in structural deformation monitoring, allowing the detection of millimetric displacements in dams, benchmarks, and buildings. They are also used in rural and urban cadastral systems, providing support for territorial management and urban planning. The implementation followed the guidelines established by the ABNT standards NBR 14166:2022 and NBR 13133:2021. The network consists of nine upper-order vertices (S), whose coordinates were adjusted based on two monuments of the Brazilian Geodetic System (SGB), namely the active station MGMT and the vertex SAT-99658, and eleven primary vertices (P), adjusted using vertices S-007 and SAT-99658 as references. During the quality control stage, the known baseline between MGMT and SAT-99658 presented an average three-dimensional difference of approximately 18 mm, which is compatible with the normative tolerance of 20 mm. The largest polygon formed by the upper-order vertices, with an approximate extension of 16 km, exhibited a three-dimensional error of about 18 mm, equivalent to 1 ppm. This value is within the limits established by the standard, estimated at approximately 26 mm. In the network adjustment, absolute constraints were initially applied, adopting MGMT and S-007 as control points. The global test indicated that the uncertainties provided by the processing software were optimistic by a factor of approximately six, which led to the rescaling of variances prior to the application of the Data Snooping method, in which no outliers were detected. Subsequently, relative constraints were applied to propagate the uncertainties of the control points. For the upper-order vertices, the worst case was observed at vertex S-004, whose 95% confidence uncertainties were approximately 8 mm in latitude, 10 mm in longitude, and 23 mm in height. Among the primary vertices, point P-006 presented the largest uncertainties, with values close to 13 mm, 14 mm, and 38 mm, respectively, at the 95% confidence level. The results demonstrate the geometric reliability of the RRCM, indicating that the adjusted vertices meet the quality standards required for cadastral and cartographic applications.
