Surveying technicians operate surveying instruments, such as electronic distance-measuring equipment.
Surveying and mapping technicians collect data and make maps of the Earth’s surface. Surveying technicians visit sites to take measurements of the land. Mapping technicians use geographic data to create maps. They both assist surveyors, and cartographers and photogrammetrists.
Duties
Surveying technicians typically do the following:
Visit sites to record survey measurements and other descriptive data
Operate surveying instruments, such as electronic distance-measuring equipment (robotic total stations), to collect data on a location
Set out stakes and marks to conduct a survey
Search for previous survey points, such as old stone markers
Enter the data from surveying instruments into computers, either in the field or in an office
Surveying technicians help surveyors in the field on teams known as survey parties. A typical survey party has a party chief and one or more surveying technicians. The party chief, either a surveyor or a senior surveying technician, leads day-to-day work activities. After data is collected by the survey party, surveying technicians help process the data by entering the data into computers.
Mapping technicians typically do the following:
Select needed information from databases to create maps
Edit and process images that have been collected in the field
Produce maps showing boundaries, water locations, elevation, and other features of the terrain
Update maps to ensure accuracy
Assist photogrammetrists by laying out aerial photographs in sequence to identify areas not captured by aerial photography
Mapping technicians help cartographers and photogrammetrists produce and update maps. They do this work on computers, combining data from different sources. Mapping technicians may use drones to take photos and collect other information required to complete maps or surveys.
Geographic Information System (GIS) technicians use GIS technology to assemble, integrate, and display data about a particular location in a digital format. GIS technicians also maintain and update databases for GIS devices.
Surveying technicians visit sites to take measurements of the land.
Surveying and mapping technicians held about 59,800 jobs in 2021. The largest employers of surveying and mapping technicians were as follows:

Most surveying and mapping technicians work for firms that provide engineering, surveying, and mapping services on a contractual basis. Local governments also employ these workers in highway and planning departments.
Surveying technicians work outside extensively and can be exposed to all types of weather. They often stand for long periods, walk considerable distances, and may have to climb hills with heavy packs of surveying instruments. Traveling is sometimes part of the job, and surveying technicians may commute long distances, stay away from home overnight, or temporarily relocate near a survey site.
Mapping technicians work primarily on computers in office environments. However, mapping technicians must sometimes conduct research by using resources such as survey maps and legal documents to verify property lines and to obtain information needed for mapping. This task may require traveling to storage sites, such as county courthouses or lawyers’ offices, that house these legal documents.
Work Schedules
Surveying and mapping technicians typically work full time but may work additional hours during the summer, when weather and light conditions are most suitable for fieldwork. Construction-related work may be limited during times of harsh weather.
Mapping technicians who develop and maintain Geographic Information System (GIS) databases generally work normal business hours.
Learning to master the equipment is a big part of the training for surveying and mapping technicians.
Surveying technicians usually need a high school diploma. However, mapping technicians often need formal education after high school to study technology applications, such as Geographic Information Systems (GIS).
Education
Surveying technicians generally need a high school diploma, but some have postsecondary training in survey technology. Postsecondary training is more common among mapping technicians where an associate’s degree or bachelor’s degree in a relevant field, such as geomatics, is beneficial.
High school students interested in working as a surveying or mapping technician should take courses in algebra, geometry, trigonometry, drafting, mechanical drawing, and computer science. Knowledge of these subjects may help in finding a job and in advancing.
Training
Surveying technicians learn their job duties under the supervision of a surveyor or a surveying party chief. Initially, surveying technicians handle simple tasks, such as placing markers on land and entering data into computers. With experience, they help decide where and how to measure the land.
Mapping technicians receive on-the-job training under the supervision of a lead mapper. During training, technicians learn how maps are created and stored in databases.
Depending on state licensing requirements, surveying technicians with many years of experience and formal training in surveying may be able to become licensed surveyors.
Important Qualities
Decisionmaking skills. Surveying technicians must be able to exercise some independent judgment in the field because they may not always be able to communicate with team members.
Detail oriented. Surveying and mapping technicians must be precise and accurate in their work. Their results are often entered into legal records.
Listening skills. Surveying technicians work outdoors and must communicate with party chiefs and other team members across distances. Following spoken instructions from the party chief is crucial for saving time and preventing errors.
Physical stamina. Surveying technicians usually work outdoors, often in rugged terrain. Physical fitness is necessary to carry equipment and to stand most of the day.
Problem-solving skills. Surveying and mapping technicians must be able to identify and fix problems with their equipment. They must also note potential problems with the day’s work plan.

Employment of surveying and mapping technicians is projected to grow 4 percent from 2021 to 2031, about as fast as the average for all occupations.
About 7,800 openings for surveying and mapping technicians are projected each year, on average, over the decade.
Many of those openings are expected to result from the need to replace workers who transfer to different occupations or exit the labor force, such as to retire.
Employment
Increased demand for map information is expected to require surveying and mapping technicians to gather and prepare related data, even as drones and other advancements make workers more efficient and limit projected employment growth.
