Mapping Technicians

Description

Calculate mapmaking information from field notes, and draw and verify accuracy of topographical maps.

Tasks

  • Check all layers of maps to ensure accuracy, identifying and marking errors and making corrections.
  • Determine scales, line sizes, or colors to be used for hard copies of computerized maps, using plotters.
  • Monitor mapping work or the updating of maps to ensure accuracy, the inclusion of new or changed information, or compliance with rules and regulations.
  • Identify and compile database information to create maps in response to requests.
  • Produce or update overlay maps to show information boundaries, water locations, or topographic features on various base maps or at different scales.
  • Trace contours or topographic details to generate maps that denote specific land or property locations or geographic attributes.
  • Lay out and match aerial photographs in sequences in which they were taken and identify any areas missing from photographs.
  • Compare topographical features or contour lines with images from aerial photographs, old maps, or other reference materials to verify the accuracy of their identification.
  • Compute and measure scaled distances between reference points to establish relative positions of adjoining prints and enable the creation of photographic mosaics.
  • Research resources such as survey maps or legal descriptions to verify property lines or to obtain information needed for mapping.
  • Form three-dimensional images of aerial photographs taken from different locations, using mathematical techniques and plotting 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 or drawings.
  • Analyze aerial photographs to detect and interpret significant military, industrial, resource, or topographical data.
  • Redraw or correct maps, such as revising parcel maps, to reflect tax code area changes, using information from official records or surveys.
  • Train staff members in duties such as tax mapping, the use of computerized mapping equipment, or the interpretation of source documents.
  • Research and combine existing property information to describe property boundaries in relation to adjacent properties, taking into account parcel splits, combinations, or land boundary adjustments.
  • Supervise or coordinate activities of workers engaged in plotting data, drafting maps, or producing blueprints, photostats, or photographs.
  • Create survey description pages or historical records related to the mapping activities or specifications of section plats.
  • Calculate latitudes, longitudes, angles, areas, or other information for mapmaking, using survey field notes or reference tables.
  • Identify, research, and resolve anomalies in legal land descriptions, referring issues to title or survey experts as appropriate.
  • Complete detailed source and method notes detailing the location of routine and complex land parcels.
  • 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.
  • Trim, align, and join prints to form photographic mosaics, maintaining scaled distances between reference points.
  • Produce presentations of surface or mineral ownership layers by interpreting legal survey plans.
