Ground surveys are methods used to collect data about the Earth's surface and its features. These surveys involve measuring distances, angles, and elevations to create accurate maps and models. They are essential in fields like geology, construction, and environmental science. Surveyors use various tools, such as theodolites and GPS, to gather information. Ground surveys can help determine property boundaries, assess land for development, and study natural resources. The data collected is crucial for planning and decision-making in many industries.
