What Does a Survey Technician Do? Duties and Job Description

The duty list has four anchors in the Bureau of Labor Statistics' profile of the occupation.

Surveying and mapping technicians visit sites to record survey measurements and other descriptive data; search for previous survey markers or set out new markers; operate surveying instruments such as electronic distance-measuring (EDM) equipment; and enter the data from surveying instruments into computers.

The field half and the office half feed each other.

BLS describes technicians helping the surveyor outdoors — clearing brush from the survey line, or using drones to take photos — and processing what the crew collected back inside: calculating angles and elevations, and drafting with CAD software.

O*NET's task list for the occupation fills in the marker and instrument work.

Its top tasks include setting out and recovering stakes, marks and other monumentation, and searching for section corners, property irons or survey points.

The office-side tasks follow: calculating latitudes, longitudes, angles and areas from field notes, entering GPS data, deeds and field notes into GIS, and adjusting and operating instruments such as prisms, theodolites, EDMs and data collectors.

Holding the rod is the classic rod-person duty on a crew: positioning and holding the vertical rod or prism pole that the instrument operator sights to measure angles, distances and elevations.

The title on the posting varies more than the work does.

Reported titles O*NET lists for the occupation include Survey Technician, Land Survey Technician, Surveying Technician, Field Surveyor, Mapping Technician, Photogrammetric Technician and Rodman — all under the single code 17-3031, since the older split codes for surveying technicians and mapping technicians were retired.

This page stays on the duties and the job description.

A survey moves through three phases — preparation, field collection, and the desk work that produces the deliverable — and the technician's duties shift with each one.

Prep.

Someone has to pull the project together before the crew rolls out.

O*NET's task list includes compiling the information needed to stake construction projects from engineering plans, and adjusting and operating the instruments the crew will use — prisms, theodolites, EDMs and data collectors.

Recording survey measurements in notes, drawings and sketches is also on the occupation's task list.

Field.

On site, the crew records the measurements.

The technician sets out and recovers stakes and monumentation, searches for section corners, property irons or survey points, and holds the rod or prism pole while the instrument measures.

Clearing brush keeps the sight line open.

On roadway work the list widens.

The Arkansas Department of Transportation's District Surveys Technician class specification adds staking and layout of highway construction, cross-section data collection, setting up safety equipment and flagging traffic.

Its hand-tool list covers setting markers and cutting brush with a sledgehammer, axe and kaiser blade.

Washington State's Transportation Technician 1 specification describes the same shape of work at the trainee level: holding rods and prism poles, chaining distances, clearing brush for line of sight, writing information on stakes and lath, setting hubs, and setting up traffic control devices.

Desk.

The wrap-up turns field data into the deliverable.

Technicians enter instrument data into computers and log GPS data, deeds and field notes into GIS.

The calculations follow: angles and elevations; latitudes, longitudes, angles and areas from the field notes; and the adjustment work — earth-curvature and atmospheric corrections, traverse closures or adjustments, azimuths and level runs — with the computations compared against applicable standards.

Preparing topographic or contour maps of the surveyed land is on the occupation's task list, and BLS notes technicians may draft in CAD software.

Drone work lands here too: O*NET's current task list includes using drone technology to capture aerial images or video for mapping.

Where does it all land?

With the licensed surveyor in responsible charge — the Model Law's term for the licensee who exercises full professional knowledge of and control over the work, holds authority to review, change, reject or approve it, and accepts full responsibility for it.

BLS frames the occupation as support: surveying and mapping technicians collect data and make maps of the Earth's surface, assisting surveyors, cartographers and photogrammetrists.

Learning often happens on the crew — BLS says technicians often learn on the job under lead staff and may begin with simple tasks.

The task list also reaches upward.

O*NET includes supervising or coordinating workers engaged in surveying, plotting data, drafting maps or producing blueprints among the occupation's tasks — a party-chief-type duty inside the same code.

Employer type shapes the reporting line.

In 2025, 60% of surveying and mapping technician jobs were in architectural, engineering and related services, 11% in local government, 9% in other support services, 4% in utilities and 1% were self-employed.

BLS notes technicians in local government may work for highway or planning departments, while many others work for firms providing engineering, surveying and mapping services on contract.

On the office side, the occupation's own task list keeps going: entering GPS data, deeds and field notes into GIS and preparing maps are on it, so where the field job ends and the office job begins moves from employer to employer.

The professional decisions stay with the licensed surveyor.

Under the NCEES Model Law — the model licensing act, not itself any state's law — work by an employee or subordinate of a licensee is exempt from licensure.

The exemption applies when that work includes no final surveying designs or decisions and is done under the responsible charge of, and verified by, a licensee.

Each state adopts its own definition of responsible charge, so the exact line sits in each state's licensing law.

That line runs through the daily work.

Finding corners, holding the rod, running the closure computations and drafting the map are all work the task lists above assign to technicians.

Under the Model Law, that work is exempt only when it meets all the conditions above: no final surveying designs or decisions, done under a licensee's responsible charge, and verified by that licensee.

The final surveying designs and decisions, and the professional responsibility that comes with the license, belong to the licensee in responsible charge.

The Model Law's definition expects that licensee to exercise full professional knowledge of and control over the work and to accept full responsibility for it.

Licensing follows the same line.

BLS states that licensing is not required for surveying and mapping technicians, and that certification is optional.

The license to practice land surveying is the state-issued credential the surveyor holds; a crew position does not carry it.

BLS describes the ramp directly: survey technicians often learn on the job under lead staff.

They may begin with simple tasks such as placing markers and entering data, and eventually help decide where and how to measure the land.

The entry rung is written out in the public class specifications.

Washington State defines Transportation Technician 1 as the trainee, beginning level of its Transportation Technician series, with high school graduation or a GED as the desirable qualification.

Its duty list for that trainee level includes holding rods and prism poles, chaining distances, learning to run a level, writing information on stakes and lath, and setting hubs.

Beyond the trainee list, the occupation's full task list is broader.

It includes adjusting and operating instruments such as prisms, theodolites, EDMs and data collectors, and running computations such as traverse closures, azimuths and level runs against applicable standards.

O*NET's 2026 task list also includes supervising or coordinating workers engaged in surveying or drafting (the party-chief-type duty from the reporting line above), using drone technology to capture aerial images or video for mapping, and writing boundary or easement legal descriptions.

Where it leads: survey technicians with many years of experience and formal training may be able to become licensed surveyors, per BLS, and mapping technicians who add education or experience may advance into cartography or photogrammetry jobs.

The step-by-step route onto a crew — requirements, first job, credentials — is in how to become a survey technician.

The sample below is drawn from public duty lists rather than any one employer's posting.

The sources: BLS's profile of surveying and mapping technicians, O*NET's task list for SOC 17-3031, and two state class specifications — the Arkansas Department of Transportation's District Surveys Technician (effective July 31, 2026) and Washington State's Transportation Technician 1.

Position: Survey Technician (field and office)

Summary: Assists the licensed surveyor on a field crew and in the office — collecting site measurements, setting and finding markers, operating surveying instruments, and processing field data into maps, staking layouts and checked calculations.

Duties:

• Visit sites to record survey measurements and other descriptive data.
• Search for previous survey markers — section corners, property irons or survey points — and set out new stakes and monumentation.
• Hold and position rods and prism poles; adjust and operate instruments such as prisms, theodolites, EDM equipment and data collectors.
• Clear brush from the survey line; set up safety equipment and flag traffic on roadway sites.
• Enter instrument data into computers; log GPS data, deeds and field notes into GIS.
• Record measurements in notes, drawings and sketches; calculate angles, elevations, latitudes, longitudes and areas; run traverse-closure and level-run computations.
• Prepare topographic and contour maps; draft in CAD software.
• Support drone photo and video capture for mapping.

Entry expectations (per BLS): a high school diploma or equivalent, with no related work experience required and moderate-term on-the-job training; employers may prefer a valid driver's license.

The physical side is real, per BLS: outdoor work in all types of weather, standing for long periods, walking harsh terrain and carrying equipment packs.

One public class specification — ARDOT's — adds lifting up to 50 pounds, standing to operate survey equipment for at least two hours without a break, frequent travel within the district, and conditions such as noise, dust and fumes.

Strengths the work leans on (per BLS): communication, decision-making, detail orientation, physical stamina and problem-solving — including identifying and fixing equipment problems.

What the sample leaves out: pay, schedules and any employer-specific experience requirement.

The entry expectations above are BLS's typical-entry profile for the occupation, not one employer's hiring bar.

Our research verified public duty lists rather than a sample of private postings, so the sample quotes no pay figure.
