Many people think that surveyors only conduct fieldwork. Surveyors can choose from many specialties and get involved at many stages of a project. Sometimes a surveyor may work in the field and then deliver the data to a surveyor who works in the office. The office-based surveyor analyzes the data, creates maps and other documents.
Land surveyors need to be current with emerging technologies such as GPS (Global Positioning System), 3D laser scanning and digital photography. GPS is used for precise positioning of points anywhere on the earth that are used in a wide variety of mapping procedures. In general, the main function of a land surveyor is measuring and mapping the earth's surface through the use of current technologies and softwares.
