A licensed surveyor and mapper makes exact measurements and determines property boundaries. They provide data relevant to the shape, contour, gravitation, location, elevation, or dimension of land or land features on or near the earth's surface for engineering, mapmaking, mining, land evaluation, construction and other purposes. The Professional Surveyor's fees will be based on the anticipated difficulty and time required to complete the project. Routine survey projects may be estimated as to cost, but the client should be aware that in many situations, the Professional Land Surveyor cannot predict the amount of work that will be required to recover necessary monuments, restore lost or obliterated corners, research city and county records, collect field data, complete mathematical calculations, and prepare descriptions and maps of the property.
