Geomatics is the field of measuring the Earth and managing the geographic data those measurements produce, with land surveying, geodesy, photogrammetry, remote sensing and GIS among its branches.
The people who work in it survey land, collect data from drones and aircraft, process imagery and manage GIS data.
This guide covers what the term means, how its disciplines relate, the careers and employers inside it, and the routes into the field.
What does geomatics mean?
Geomatics is the umbrella term for the sciences and technologies that measure the Earth and manage the geographic data those measurements produce.
In practice, it is the field that answers where things are, and turns the answers into boundaries, maps, models and datasets.
BLS describes geomatics as combining a variety of disciplines, such as engineering, natural resources and mathematics.
Because it is a field of fields, the word describes a territory better than any single job: land surveying, geodesy, photogrammetry, remote sensing and GIS all sit inside it, and job titles follow those branches.
Federal statistics show the same structure.
BLS has no separate geomatics engineer occupation; its closest occupations are surveyors (SOC 17-1022) and cartographers and photogrammetrists (SOC 17-1021), while O*NET profiles GIS technologists and technicians and remote sensing technicians as occupations of their own.
The licensed side has a formal definition too.
The NCEES Model Law, revised in August 2026, defines the practice of surveying as using sciences such as mathematics, geodesy and photogrammetry to make geometric measurements of the earth's physical or legal features.
Those measurements are then developed into survey products: graphics, data, maps and reports.
The Model Law is NCEES's template statute for state boards, not any state's law.
Geomatics also names a degree field.
The Model Law counts geomatics within its definition of a surveying degree, alongside surveying, surveying engineering, mapping and geodesy, and BLS lists geomatics among the bachelor's majors that typically prepare people for cartographer and photogrammetrist work.
Neighboring labels circle much of the same territory — geospatial, geoinformatics, surveying engineering.
The labels overlap, so it pays to read what a program or posting actually covers rather than going by the name alone.
The disciplines inside geomatics
The branches below map onto the degree names and job titles the field uses.
They overlap on real projects, but each has its own question to answer.
Land surveying is the licensed measurement branch.
The BLM's Manual of Surveying Instructions defines surveying as measuring and locating points, lines, angles and elevations on the Earth's surface, including underground workings and the beds of water bodies.
Boundary work is surveying's legal core.
In the same manual's words, a cadastral survey creates or re-establishes, marks and defines the boundaries of tracts of land, and the word cadastral traces to the cadastre — a public record of the value, extent and ownership of land as a basis of taxation.
The record behind it is large by any measure.
Of more than 1.8 billion acres of acquired public domain, almost 1.5 billion acres have been surveyed into townships and sections, and the BLM still completes new surveys each year, mostly in Alaska.
For the career itself, start with the land surveying career guide — it covers the role, the license and the state-by-state rules.
Geodesy is the reference-frame science the other branches build on.
NOAA defines geodesy as the science of accurately measuring and understanding the Earth's geometric shape, orientation in space and gravity field.
Geodesists model the planet with the ellipsoid — a smooth mathematical surface — and, for more detail, with the geoid, which closely resembles global mean sea level.
The work reaches past the lab: NOAA notes that building roads and bridges, conducting land surveys and making maps all depend on spatial reference systems geodesists create.
The geodetic surveyor career guide covers the role.
Photogrammetry measures from photographs.
O*NET's task list for the occupation includes compiling aerial photographs, survey notes and records for map preparation, and delineating control points, hydrography, topography and cultural features using precision stereoplotting apparatus.
Reported titles in the branch include Aerial Photogrammetrist, Photogrammetric Technician, Stereo Compiler and Stereoplotter Operator.
The photogrammetrist career guide covers the role end to end.
Remote sensing collects geospatial data from aircraft, drones and satellites.
O*NET lists Remote Sensing Technicians as an occupation that applies remote sensing technologies, may prepare flight plans or sensor configurations, and collects geospatial data using aerial photography.
Its task list also includes operating remote sensing equipment on drones to collect data in areas that are difficult to access or need high-resolution imagery.
GIS is the branch that organizes what the measuring produces.
O*NET describes GIS technologists and technicians as assisting scientists and related professionals in building, maintaining, modifying or using GIS databases.
The GIS technician career guide covers that role.
Hydrography extends the same measurement idea to water.
NOAA defines hydrography as the science that measures and describes the physical features of the navigable portion of the Earth's surface and adjoining coastal areas, and names surveying with multibeam echo sounders as the primary method of obtaining hydrographic data.
Geomatics vs surveying vs GIS
The three terms sit at different levels.
Geomatics is the umbrella field; surveying is the licensed measurement practice inside it; GIS is the data-management branch that stores and serves what the measuring produces.
Photogrammetry and remote sensing are the imaging branches, and geodesy is the reference-frame science the rest rely on.
On real projects the branches converge.
BLS describes cartographers and photogrammetrists as integrating land surveys and LiDAR using GIS, CAD and other software to build maps; BLS groups both titles into a single occupation (SOC 17-1021) and does not give separate counts for photogrammetrists.
The license line runs through the middle of the field.
BLS reports that all 50 states and DC require surveyors to be licensed before providing services to the public, while licensing for cartographers and photogrammetrists varies, may be state- or employer-specific and depends on duties, with certification usually optional.
That is why one project can carry several titles at once: a crew measuring a boundary, an analyst maintaining the GIS layers and a photogrammetrist compiling aerial photographs for maps are all working in geomatics.
Whether a particular task requires a license is a question of state law, not of job title.
For the role-level view — what a geomatics engineer does day to day and how the title relates to licensure — the geomatics engineer career guide takes the role's side of that question.
Scope of practice is the board's call
Geomatics careers and who hires for them
The branches lead to named seats: surveyor and surveyor in training on the licensed side, and photogrammetrist, stereo compiler and stereoplotter operator in the imaging pipeline.
On the data and capture sides sit GIS technicians, remote sensing technicians and drone and LiDAR specialists, with geodesists in reference-frame work.
The BLS figures below come from the two closest BLS occupations.
Surveyors (SOC 17-1022) cover the licensed measurement side, and cartographers and photogrammetrists (SOC 17-1021) cover the mapping side, with no separate photogrammetrist counts.
The employer mix differs by branch.
Among cartographers and photogrammetrists in 2025, the largest employers were local government (41%), architectural, engineering and related services (22%), management, scientific and technical consulting (5%), federal government (4%) and state government (4%).
Surveying-side employment sits heavily in private practice: 71% of surveyor jobs in 2025 were in architectural, engineering and related services, with 10% in construction and 9% in government.
Projected demand points the same direction on both sides.
BLS projects surveyor employment to grow 6% from 2025 to 2035, faster than the 3% projected for all occupations, and projects 7% growth for cartographers and photogrammetrists — much faster than average — with about 900 openings a year.
Federal agencies hire directly into the field's branches.
NOAA's Office of Coast Survey conducts hydrographic surveys and creates nautical charts of U.S. waters; NOAA and its commercial contractors survey 2,000-3,000 square nautical miles of U.S. waters a year, against 43,000 square nautical miles considered critical to navigation.
Federal job series exist for the professional branches, too.
OPM's federal Land Surveying Series accepts a degree in land surveying.
It also accepts civil engineering with a surveying option that includes at least 6 semester hours of surveying, 3 semester hours of land law and 21 more in surveying-related subjects — or current state registration obtained by written exam.
The separate federal Geodesy Series asks for a geodesy degree or 30 semester hours across geodesy, mathematics, physics and related fields, including calculus.
The setting spans field and office.
BLS describes cartographers and photogrammetrists as spending much of their time in an office, though some jobs require fieldwork to collect data and verify results, and most work full time.
Open roles are listed on the geomatics engineer jobs page, and each branch's role guide links its own listings.
How to enter the field
People arrive from two directions: through a geomatics or surveying degree, or up through a survey crew.
Which route fits depends on the branch you want and the state where you plan to work.
The degree route is the mapping side's typical entry.
BLS says cartographers and photogrammetrists typically need a bachelor's degree in cartography, geography, geomatics, surveying or a related field, and that some people in these roles may need to be licensed.
The credential picture is wider than one degree, though.
In O*NET's education survey for the occupation, 36% of respondents said a new hire needs a post-secondary certificate and 30% a bachelor's degree.
Which program to choose — certificate, associate, bachelor's or master's — is an education question, and the surveying degree comparison lays out the options side by side.
The crew route starts on the ground, in roles like rod person, instrument operator and party chief, and the surveying career path follows that ladder from first job to licensed surveyor and beyond.
Credentials stack once a branch is picked.
The license is the state's credential: all 50 states and DC require surveyors to be licensed before providing services to the public.
Boundary work and the legal documents that show property lines run through a state board, and BLS notes that licensing for the mapping roles varies with the duties.
Where the goal is a surveying license, the route — exams, qualifying experience and the license itself — is the how to become a land surveyor guide's subject.
Voluntary certifications mark the mapping specialties.
ASPRS certifies at two levels, Mapping Scientist and Technologist, in Photogrammetry, Remote Sensing, Lidar and UAS.
The Scientist level requires 6 years of active experience in the specialty and the Technologist level 3 years.
Both require peer appraisal and a written exam, and the program is open to non-members.
In hydrography, NSPS and THSOA run a joint certification program with two levels: Certified Master Hydrographer and Certified Hydrographer.
Whichever branch you aim at, the entry point looks similar: measurement fundamentals, comfort with the software the branch runs on, and a first season on a crew or in a production office.
Career information, not legal or licensing advice. Licensure and certification rules change; confirm current requirements with your state licensing board, NCEES or the body that issues each credential.
