Geodetic surveying techniques have evolved over time to measure and map the Earth's surface with increasing accuracy. Early methods relied on basic tools like chains, compasses, and transits. The advent of triangulation in the 18th century revolutionized surveying by allowing distances and angles to be measured more accurately. The establishment of networks of fixed points enabled precise measurements over large distances.
With the rise of technology, theodolites and total stations became common tools in the 20th century. These devices improved accuracy and enabled surveyors to measure horizontal and vertical angles more precisely. In recent decades, the use of satellite-based systems like GPS has further revolutionized geodetic surveying. GPS allows surveyors to determine their position with high accuracy and has become a standard method for many applications.
Today, geodetic surveying techniques continue to advance with the integration of technologies like laser scanners, drones, and advanced computer algorithms. These advancements enable more efficient data collection and analysis, leading to increasingly detailed and accurate geospatial information.
