Levantamento planialtimétrico com uso de drone e RTK na regularização fundiária urbana na cidade de Orizona-GO.

Abstract

This study highlights the execution of a planialtimetric survey for land regularization, mapping an irregular area located in the municipality of Orizona-GO, aiming to qualify and correct notarial records. Currently, global navigation satellite systems and total stations are the most commonly used tools for obtaining topographic data. However, with technological advancements, the use of drones integrated with the GNSS (Global Navigation Satellite System) e RTK (Real-Time Kinematic) system enables real-time measurements, making it a promising technique. This study presents the characteristics and fundamental steps for conducting a proper survey and mapping according to legislation on REURB (Urban Land Regularization), ensuring an efficient and legal process. The planialtimetric survey was conducted in the Egerinêo Teixeira district in the city of Orizona-GO. Planning, an essential stage of any project, involved delimiting the area of interest, distributing and quantifying the points to be collected, and analyzing regional conditions such as altitude variation, wind regime, and climatic conditions. Using a GNSS and RTK, control points were collected, and the same area was imaged with a drone. By processing the data collected in the field, it was possible to obtain the digital terrain model, orthorectification of the images, and the production of the final mosaic (orthophoto). The application of the generated orthophoto allows the creation of an area and subdivision map, highlighting the urban inconsistencies of the surveyed area and characterizing them to make it possible to register these properties with the city's land registry office.
