The study presents the importance of rainfall in soil erosion, exploring the Erosivity (R) factor of the Universal Soil Loss Equation (USLE) model, which assesses the erosive potential of rainwater. It also highlights the role of Geographic Information Systems (GIS) in analyzing and interpolating this data to understand spatial patterns of rainfall and erosion. The study aimed to estimate rainfall erosivity and its relationship with land use in Goiás in different years. The relationship between erosivity and land cover for the state of Goiás showed an increase in agricultural area, a reduction in forest cover and an impact on susceptibility to erosion, especially in areas without vegetation cover.

In this context, the technique of real-time positioning (RTK) using corrections transmitted by the Networked Transport of RTCM via Internet Protocol (NTRIP) stands out. This research aims to evaluate the data quality collected through the RTK technique, supported by the use of NTRIP to obtain the differential corrections required using the RBMC-IP (Brazilian Network for Continuous Monitoring of GNSS Systems in real-time). For this propose, 09 landmarks were planed and surveyed at approximately 10 km intervals, starting from the GOGY base located in Goiânia and following along the BR-153 federal highway in a baseline of approximately 81 km. The landmarks were surveyed using the RTK positioning method via NTRIP, evaluating the time for ambiguities solutions and the type of solutions, and were compared to the static relative method, which was used as a reference for positional accuracy computation. About the ambiguity resolution, all points were determined with a fixed solution, but up to 50 km, it was observed that even with a fixed solution, there was instability in the quality of the coordinates. In the accuracy analysis, root mean square (RMS) error values were obtained between 3.86 cm and 40.33 cm for planimetry and between 9.19 cm and 38.73 cm for altimetry.
