What Does a Land Surveyor Do? Duties, Work Products and Typical Week

A land surveyor's main job is to determine where boundaries and features lie on the ground, and to certify the answer.

BLS lists the typical duties:

• Search legal records, survey records and land titles.
• Measure distances and angles, and use known reference points to locate features.
• Record results and verify their accuracy.
• Prepare or supervise plots, maps and reports.
• Present findings to clients.
• Establish official land and water boundaries for deeds, leases and other legal documents, and testify in court about survey work.

O*NET adds the professional weight behind those steps.

Its task list describes surveyors preparing and maintaining sketches, maps, reports and legal descriptions of surveys that describe, certify and assume liability for the work performed.

That certification — the surveyor taking legal responsibility for the work performed — is the thread running through every duty on the list.

The license is what makes the certification legal.

All 50 states and the District of Columbia require surveyors to be licensed before providing services to the public, and certifying legal documents that show property lines is one of the services states reserve for license holders.

BLS lists the qualities the work draws on: communication, detail orientation, physical stamina, problem-solving, time management and visualization.

If you are weighing the profession as a whole — the route to the license, pay and the ladder from rod person to PLS — our land surveyor career guide covers it.

The job runs on two tracks.

In the field, BLS says surveyors use handheld GPS units and robotic total stations — instruments that automate positioning of a telescope.

The fieldwork itself is outdoors in all weather: walking long distances, standing for long periods, sometimes climbing hills with heavy instrument packs, and wearing brightly colored or reflective vests near traffic.

The licensed surveyor's field role leans toward direction and checking.

O*NET's surveyor tasks include directing surveys to establish legal boundaries from deeds and titles, and training and directing assistants; BLS notes that entry-level surveyors often work under a licensed surveyor for several years before qualifying for a license.

The crew runs the instruments; the surveyor's listed tasks are deciding what gets measured, holding the work to the deed lines, and verifying the accuracy of the data that comes back.

Back in the office, the same professional works in GIS and CAD software, per BLS.

O*NET's software list for surveyors includes Autodesk AutoCAD Civil 3D, Bentley MicroStation, Esri ArcGIS, HYPACK MAX, MicroSurvey FieldGenius and Leica Cyclone.

This is where field data becomes a deliverable: adjusting and checking measurements, drafting the plat or map, and writing the legal description that will carry the seal.

O*NET frames the output as the sketches, maps, reports and legal descriptions that certify the work.

Technology keeps moving parts of the measurement work.

BLS notes that drones and other advances make some survey work more efficient, and that surveyors will still be needed to review and interpret the output of these technologies — the review is where the license stays in the loop.

The deliverable changes with the assignment.

These are the core work products:

• Boundary surveys and retracement. Research the deed chain and survey records, find the original monuments, and re-establish the lines the records describe. On surveys of the public lands, the BLM's Manual of Surveying Instructions restates the common-law rule that monuments control over measurements, with original corners left undisturbed and discrepancies distributed proportionally between accepted corners. The Manual also separates the corner — the point determined by the surveying process — from the monument, the physical object that marks it.
• ALTA/NSPS Land Title Surveys. Worked under the 2026 ALTA/NSPS Minimum Standard Detail Requirements, effective February 23, 2026, which supersede every earlier version including the 2021 standards. A complete survey combines the Section 5 fieldwork, the Section 6 plat or map, whatever optional Table A items the client selected, and the Section 7 certification.
• Topographic surveys. Determining the configuration or contour of the earth's surface, which the NCEES Model Law lists among the practice of surveying, so the finished map of features and elevations gives engineers and designers something to plan on.
• Construction layout. Locating or laying out alignments, positions and elevations for the construction of fixed works — the Model Law's phrase for the work that marks where a designed improvement sits so a contractor can build to the plan. Whether a given state treats contractor layout as surveying is that state's own statute's call.
• FEMA Elevation Certificates. Section C, the building elevation information, may be signed only by a land surveyor, engineer or architect authorized by state law, who adds license number, seal, signature and date. Elevations must use the same datum as the base flood elevation, and Section C is also completed when the certificate supports a LOMA, CLOMA, LOMR-F or CLOMR-F request.
• Records of survey and corner records. Filing duties that follow fieldwork where state law requires them. In California, for example, a licensed land surveyor or civil engineer files a record of survey with the county surveyor when, among other cases, a field survey finds material evidence or physical change not shown on recorded maps, or a material discrepancy with recorded maps. Points and lines set or reestablished that appear on no recorded map trigger the filing too.

Plats and legal descriptions thread through all of it: O*NET lists writing boundary descriptions for deeds and leases among the core surveyor tasks.

Parts of this job are reserved for the license holder.

Providing surveying services to the public is the gate: all 50 states and the District of Columbia require it, including certifying legal documents that show property lines.

The Model Law definition shows how far the reserved work reaches.

Under the NCEES Model Law — the template NCEES publishes for state licensing laws, not the law of any state — the practice of surveying includes determining the size and shape of the earth by geodetic surveys.

It also includes determining the position of, establishing or replacing any survey monument, whether or not it marks a boundary.

Each state's statute writes the version that governs its own license holders.

Sealing is the visible act.

An ALTA/NSPS plat must carry the surveyor's name, license number, signature and seal.

O*NET's wording for the task list is blunt: the maps and legal descriptions a surveyor produces certify the work and assume liability for it.

Court work sits at the same professional end.

BLS lists establishing official land and water boundaries and testifying about survey work among surveyor duties, and O*NET lists testifying as an expert witness in court cases on land survey issues, such as property boundaries, as a surveyor task.

Everything on this list shares one feature: a person's signature takes responsibility for it.

Crew members, CAD technicians, GIS staff and drone pilots all feed the work; the certification step is the licensee's.

A surveyor rarely works alone.

The crew — rod person, instrument operator, party chief — gathers the measurements, and the surveyor's own task list includes training and directing those assistants.

Office staff in CAD and GIS turn field data into deliverables, and O*NET lists coordinating with engineering and architectural staff and clients among surveyor tasks.

On land title work, the counterparts sit in the title and lending world.

The surveyor works from the most recent title commitment — or other title evidence acceptable to the insurer — plus the current record description and the recorded easements that burden or benefit the property.

ALTA's FAQ notes that an ALTA survey is often ordered by a buyer or seller while the primary consumers are the lender and the title insurer, which is why scope questions can continue after delivery.

Public-sector counterparties appear when the work is filed: in California, the county surveyor examines a required record of survey before it is filed with the county recorder.

Above the whole list sits the state licensing board that issued the license — the body that administers the credential under the state's statute and rules.

Clients round it out: presenting findings to clients is on BLS's duty list, and those findings often land in someone's design documents, title policy or construction plan.

There is no single official answer to the hours question.

BLS says most surveyors work full time and may have longer workdays while fieldwork is underway, and BLS publishes no weekly-hours or overtime figure for surveyors.

In O*NET's work-context survey, 55% of surveyor respondents reported a typical 40-hour week.

The shape of a week follows the project calendar.

Research days go to deeds, records and title documents; field days go to control, measurements and monument work; office days go to computations, drafting and checking; and the sealing, signing and filing steps anchor the end of a job.

Deadlines are real: in California, a required record of survey must be filed within 90 days after boundary monuments are set or the field survey is completed, whichever comes first.

Weather and travel bend the schedule.

Fieldwork happens outdoors in all weather, and BLS says travel is often part of surveying — some surveyors commute long distances, and those on resource-extraction projects may work in remote areas and spend long periods away from home.

In O*NET's work-context survey of surveyors, 60% of respondents said they work outdoors exposed to all weather every day, and 47% said they work indoors in a controlled environment every day — the same O*NET work-context survey behind the 40-hour figure.

Both can be true in the same week.
