Answer questions and provide information to the public or to staff members regarding assessment maps, surveys, boundaries, easements, property ownership, roads, zoning, or similar matters.
Complete detailed source and method notes describing the location of routine or complex land parcels.
Adjust and operate surveying instruments such as prisms, theodolites, electronic distance measuring equipment, or electronic data collectors.
Collect information needed to carry out new surveys, using source maps, previous survey data, photographs, computer records, or other relevant information.
Conduct surveys to ascertain the locations of natural features and man-made structures on the Earth's surface, underground, and underwater, using electronic distance-measuring equipment, such as GPS, and other surveying instruments.
Enter Global Positioning System (GPS) data, legal deeds, field notes, or land survey reports into geographic information system (GIS) workstations so that information can be transformed into graphic land descriptions, such as maps and drawings.
Perform calculations to determine earth curvature corrections, atmospheric impacts on measurements, traverse closures or adjustments, azimuths, level runs, or placement of markers.
Prepare cost estimates for mapping projects.
Prepare topographic or contour maps of land surveyed, including site features and other relevant information, such as charts, drawings, and survey notes.
Record survey measurements or descriptive data, using notes, drawings, sketches, or inked tracings.
Search for section corners, property irons, or survey points.
Set out and recover stakes, marks, or other monumentation.
Supervise or coordinate activities of workers engaged in surveying, plotting data, drafting maps, or producing blueprints, photostats, or photographs.
