1. Land surveyors assess a particular area for the purpose of development, and to measure and map the area. 2. Land surveyors used advanced technology such as GPS, Robotic Total Stations (Theodolites), and aerial and terrestrial scanners. 3. Some of the tasks of a land surveyor is to make exact measurements and determine property boundaries and to collect and provide data on the location, contours, gravitation, elevation and features of an area for land evaluation, mining, construction, mapmaking and other purposes. 4. A surveyor verifies the accuracy of the survey data including the measurements and calculations conducted at survey sites. 5. He/she also writes descriptions of property boundary surveys which would be used in deeds, leases and other legal documents.
