Comparative case study between different topographic measuring devices, such as total station and geodetic GPS

In recent decades, there have been several technological advances in the field of agriculture, making it increasingly necessary for topographic surveys to be performed quickly and accurately. Even so, evaluating these advances, the main one was the possibility of performing topographic surveys using satellite depth systems. The various methods for performing a topographic survey have different characteristics of functionality, effectiveness, agility and precision that can be obtained in different situations. Regardless of the equipment used and the method performed with it, all types of surveys generate errors that can be minimized, but are not completely eliminated. This research aims to establish a comparative study for topographic surveys performed with a total station and geodetic GPS. To this end, a topographic survey of a polygon was performed with a total station and with GNSS in order to establish a comparison of results between distance measurements, verifying the most accurate and productive method based on the characteristics of the elevated area. The results found indicate that the total station presents greater precision, but satellite surveys prove to be more practical and agile.
