IMPORTANCE OF GEODESY IN CIVIL ENGINEERING AND IN THE REGISTRATION OF URBAN AND RURAL LOTS: A VIEW ON GEODESIC POSITIONING WITH GPS

Abstract

This article addresses the importance of Geodesy in Civil Engineering and in the registration of urban and rural lots, with emphasis on Geodetic Positioning with GPS. Geodesy is a discipline that studies the shape, size and irregular surface of the Earth. It plays a key role in Civil Engineering, providing essential information for infrastructure projects, construction, mapping and lot registration. Geodetic Positioning with GPS has become increasingly relevant, allowing the precise determination of geodetic coordinates, measuring distances, angles and areas. This information is extremely important for the proper registration and identification of properties in urban and rural cadastres, ensuring the correct delimitation of lots and data reliability. This article offers an overview of the fundamental concepts of Geodesy, exploring the basic operation of the GPS system, the equipment used in geodetic mapping and the importance of proper treatment of the data obtained. In the introduction section, we highlight the relevance of Geodesy in Civil Engineering and in the registration of urban and rural lots, emphasizing the need for accurate information for making decisions and carrying out projects efficiently. Then, we present the main objectives of this article, which is to provide a comprehensive view on Geodesy, Geodetic Positioning with GPS and its impacts on the mentioned areas. By understanding the essential concepts of Geodesy and the functioning of the GPS system, it is possible to perceive the potential of this technology for Civil Engineering and the registration of lots. In addition, we discuss the equipment used in geodetic mapping, highlighting the importance of choosing the right devices to ensure the accuracy of the results. Finally, we address the importance of proper treatment of data obtained in geodetic positioning. This involves differential correction, which takes into account atmospheric corrections and other factors that can affect the accuracy of measurements. We also emphasize the need to use geodetic reference systems to perform the transformation of coordinates obtained by GPS in relation to a specific system. In conclusion, this article highlights the relevance of Geodesy in Civil Engineering and in the registration of urban and rural lots, demonstrating how Geodetic Positioning with GPS provides essential information for projects and accurate records. Knowledge of fundamental concepts, the proper use of equipment and the correct treatment of data are key elements to ensure reliable and high quality results in geodetic activities.
