Job description
A lot of the work involves compiling raw source material, aerial photographs, survey notes, existing maps, and translating it into finished maps, charts, or three-dimensional terrain models using stereoscopic plotting equipment and computer graphics software. Cartographers also study legal records to establish property boundaries and use standard mathematical formulas to identify and orient geodetic points and elevations precisely. Many now work with Geographic Information Systems (GIS), and some design the algorithms, data structures, or interfaces behind mapping software itself rather than just producing individual maps. The work is desk-based and team-oriented, with real emphasis on precision since a small error can compound into an inaccurate map.
Pros
- Faster than average projected growth (6.4%)
- Specialized, technical work blending GIS, legal research, and spatial data analysis
- Comparatively humane hours, capped around 45 per week
Cons
- Very small field nationally (about 1,000 jobs), so openings are geographically limited
- Precision is essential, since small errors can misstate legal property boundaries
- Pay tops out under $127k, a modest ceiling for the technical skill required
A typical day
The county's new aerial imagery landed overnight — 900 frames from a photogrammetric flight — and the morning is spent in the software triangulating them into a seamless, measurable surface: control points checked, elevation models built, and the accuracy report run because a map that lies about where things are is worse than no map. Midday shifts to the cartographer's craft proper: a public trail map in progress, where every choice — which streams to name, how to shade relief, what the colorblind will see — is editorial judgment wearing technical clothes. An afternoon request comes from emergency services needing flood-zone boundaries overlaid on parcels by Friday. Drone imagery from a landslide site gets processed before close. The work marries geodesy's rigor with design's persuasion: making the world legible, at scale, on purpose.
Tasks at the job
- Compile data required for map preparation, including aerial photographs, survey notes, records, reports, and original maps.
- Delineate aerial photographic detail, such as control points, hydrography, topography, and cultural features, using precision stereoplotting apparatus or drafting instruments.
- Prepare and alter trace maps, charts, tables, detailed drawings, and three-dimensional optical models of terrain using stereoscopic plotting and computer graphics equipment.
- Study legal records to establish boundaries of local, national, and international properties.
- Inspect final compositions to ensure completeness and accuracy.
- Identify, scale, and orient geodetic points, elevations, and other planimetric or topographic features, applying standard mathematical formulas.
Workplace & working conditions
Work happens indoors in a climate-controlled setting, and most of the day is spent sitting at a desk.
There's a regular, moderate amount of time pressure, and you're expected to exercise significant independent judgment day to day. Precision and accuracy are essential to the work. Almost all of the work is done as part of a team.
