Land surveyors play a critical role in the growth of Vermont's infrastructure. What do land surveyors do? They measure properties and pieces of land to determine boundaries — information that's necessary for a lot of reasons. It helps determine where roads or buildings will be constructed, settles property line disputes, and leads to the creation of maps. The maps and land descriptions created by a land surveyor are usually considered legally binding, and surveyors are sometimes called on to present their findings in a courtroom setting.
