Cadastral Surveyor Career Guide: BLM, CFedS and Public Land Surveys

The BLM's Manual of Surveying Instructions gives the working definition: a cadastral survey "creates or reestablishes, marks, and defines boundaries of tracts of land."

A cadastral surveyor is the person who does that work — determining where the lines run, marking them on the ground and defining them in the record.

The name is older than the agency.

BLM traces "cadastral" to cadastre, "a public record, survey, or map of the value, extent and ownership of land as a basis of taxation," and dates its own Cadastral Survey program to the Land Ordinance of 1785.

In the United States, that program built and maintains the Public Land Survey System.

The PLSS was established by the Land Ordinance of 1785.

It typically describes townships of 36 square miles made up of sections of 1 square mile (640 acres, more or less), quarter sections (160 acres) and quarter-quarter sections (40 acres).

Per the BLM Manual, thirty of the 50 states were originally surveyed under the PLSS.

The other 20 — the thirteen original states plus Hawaii, Kentucky, Maine, Tennessee, Texas, Vermont and West Virginia — were surveyed under other systems.

The grid matters well beyond federal land.

Since 1785 it has been continuous US policy that land does not leave federal ownership until it has been surveyed and an approved plat filed.

In the 30 PLSS states, nearly all private chains of title trace back to a federal patent or grant.

So the title covers three working situations in the US: career federal surveyors inside the BLM's program, BLM Indian Lands Surveyors serving tribal lands, and state-licensed surveyors who qualify as Certified Federal Surveyors to work on federal interest lands.

The rest of this guide takes each in turn.

BLM's Cadastral Survey program creates, defines, marks and re-establishes the boundaries and subdivisions of US public lands, and the agency traces the program to the Land Ordinance of 1785.

The scale is vast.

Of over 1.8 billion acres of acquired public domain, almost 1.5 billion acres have been surveyed into townships and sections.

BLM keeps over 200 years of cadastral records and plats, still completes new surveys each year — mostly in Alaska — and conducts resurveys to restore obliterated or lost original survey corners.

The mandate is broad.

BLM states that it is required to perform cadastral surveys on all federal interest and Indian lands, and it maintains the PLSS grid that is the basis for legal descriptions.

The program also publishes the technical tools the work runs on: GPS standards for cadastral surveys, the Specifications for Descriptions of Land (revised 2017) and BLM surveying glossaries.

The rulebook is the Manual of Surveying Instructions for the Survey of the Public Lands of the United States.

The 2009 edition is the most recent version and the ninth in the series, and official Manuals have guided public-land surveys since 1855.

Because each survey is governed by the edition in force when it was made, earlier editions still matter in retracement.

One branch works Indian trust and restricted lands.

BLM Indian Lands Surveyors (BILS) support the Bureau of Indian Affairs and tribes by providing cadastral survey services, and each BILS is assigned to a specific BIA region.

The field routine may look familiar to a private boundary surveyor; the legal frame around the lines is where the work divides.

Controlling law comes first.

Per the Manual, the controlling law for a boundary is generally the law under which it was created.

A section line is generally controlled by federal law even if no federal land is now involved, while boundaries created under state law depend on whether the state has adopted the Manual or another standard.

Adverse possession is the sharpest line.

The Manual states that doctrines of adverse possession do not apply against the United States.

On federal interest lands, stability comes from protecting the lines actually run and marked in the official survey — not from the common-law doctrines such as adverse possession or acquiescence that shape non-federal boundaries.

The title record runs federal as well.

Because land has not left federal ownership unsurveyed since 1785, nearly all private chains of title in the 30 PLSS states trace back to a federal patent or grant.

A private boundary survey in a PLSS state retraces lines that ultimately hang on that federal record.

The working relationship differs too.

Cadastral services on federal interest lands are performed under the direction and control of the BLM, whether by the agency's own surveyors or by Certified Federal Surveyors, who must follow the current Manual.

An ordinary private commission, by contrast, follows the controlling-law principle that opened this section: the law under which each boundary was created.

There are two doors into this field: a federal surveying position, or a state license followed by the federal certification.

Both lead to cadastral work; the employers and the paperwork differ.

The federal employee route runs through the Office of Personnel Management's qualification standard for the Land Surveying Series, GS-1373.

Its basic education requirement is a degree in land surveying, or in civil engineering with a surveying option.

That option must include at least 6 semester hours of surveying, 3 semester hours of land law and 21 additional semester hours in surveying-related subjects such as photogrammetry, geodesy, route surveying, remote sensing, cartography and survey adjustments.

The standard allows two alternatives: an equivalent combination of education and experience, or full qualification on a current state land surveyor registration obtained by written examination under requirements equivalent to the model law.

A state license earned by examination can therefore satisfy the series' basic requirement on its own.

Below the professional series sits a separate one for technicians, GS-0817.

OPM fills it by specialized surveying experience or postsecondary education, and classifies it as technician work rather than licensed-surveyor work.

The contract route starts with the state license instead.

The Certified Federal Surveyor program, covered below, exists to train and test surveyors who already hold a state license.

Licenses are issued by state and territory licensing boards, not by NCEES, and requirements vary by state — so the first step is the licensing rules where you plan to work.

CFedS stands for Certified Federal Surveyor.

BLM Manual 9687, released in 2006, establishes the program, and its stated purpose is to train and test state-licensed land surveyors to provide cadastral services for federal interest lands — especially Indian trust lands — under the direction and control of the BLM.

Two anchors define the credential.

First, it sits on top of a state license: the program certifies surveyors who are already licensed by a state, so a CFedS certificate is not itself a license.

Second, a CFedS must follow the current BLM Manual of Surveying Instructions — the same rulebook the agency's own surveyors work under.

Administration is shared.

BLM describes CFedS as co-administered by the BLM and the National Society of Professional Surveyors (NSPS).

BLM also leads the Interagency Cadastral Coordination Council of federal agencies that require or conduct boundary surveys, among them the Bureau of Indian Affairs, Reclamation, BOEM, the National Park Service, the Office of Surface Mining, the Forest Service, the Fish and Wildlife Service, the USGS and NGS.

For eligibility details, the examination and renewal mechanics, use the program's own materials from BLM and NSPS — this page covers what the program is, not its application rules.

The employers in this field are distinct and identifiable, which makes the job search more targeted than a general one.

The federal side centers on the BLM, including the Indian Lands Surveyor positions serving Bureau of Indian Affairs regions.

The other agencies of the Interagency Cadastral Coordination Council named above all require or conduct boundary surveys.

Federal land surveying positions are classified in the GS system — GS-1373 for the professional series, GS-0817 for technicians.

The private side is the contract route: state-licensed surveyors working through the CFedS program take on cadastral services for federal interest lands under BLM direction and control.

Geography matters when you read postings.

Per the BLM Manual, thirty of the 50 states were originally surveyed under the PLSS.

The township-and-section framework therefore runs through those public domain states.

New surveys are completed each year, mostly in Alaska, and BLM conducts resurveys to restore obliterated or lost original survey corners.
