Surveyors are professionals who measure and map land to determine property boundaries and create accurate representations of the Earth's surface. They use tools like theodolites and GPS technology to collect data, which helps in planning construction projects, roads, and other developments. Their work is essential for ensuring that buildings and infrastructure are built in the right locations. In addition to measuring land, surveyors also prepare detailed reports and maps that are used by architects, engineers, and urban planners. They play a crucial role in real estate transactions, helping buyers and sellers understand property lines and any potential issues. Their expertise ensures that land is used effectively and legally.
