GPS Surveying is a modern method of measuring and mapping land using satellite technology. It's like having a very precise digital map-making tool that helps surveyors determine exact locations and heights of different points on the ground. Instead of older methods with traditional survey equipment, surveyors now use specialized GPS receivers that communicate with satellites to get highly accurate measurements. This technology is essential in construction, mining, and mapping projects. You might also see it referred to as "GNSS Surveying" or "Satellite Surveying" in job descriptions.
