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, cartographers, and photogrammetrists.
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 to 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 upgrade maps. They do this work on computers, combining data from different sources.
Geographic Information System (GIS) technicians use GIS technology to assemble, integrate, and display data about a particular location in a digital format. They also use GIS technology to compile information from a variety of sources. GIS technicians also maintain and update databases for GIS devices.
The median annual wage for surveying and mapping technicians was $42,450 in May 2016. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $26,030, and the highest 10 percent earned more than $70,280.
Surveying and mapping technicians typically work regular schedules but may work additional hours during the summer, when weather and light 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.
Employment of surveying and mapping technicians is projected to decline 8 percent from 2014 to 2024. Advancements in surveying technology, such as robotic total stations, let surveyors and surveying technicians complete more work in less time, reducing the demand for surveying technicians.
Some job openings will result from the need to replace workers who leave the occupation. Demand for surveying services is closely tied to construction activity, and job opportunities will vary by geographic region, often depending on local economic conditions. When real estate sales and construction activity slow down, surveying technicians may face greater competition for jobs. However, because surveying technicians can work on many different types of projects, they may have steadier work than others when construction slows.
Prospects should be best for those who are trained in Geographic Information Systems (GIS).
EDUCATION AND TRAINING NEEDED
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).
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 will help in finding a job and in advancing.
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 to 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.
Licenses, Certifications, and Registrations
The growing need to make sure that data are useful to other professionals has caused certification to become more common. The American Society for Photogrammetry and Remote Sensing (ASPRS) offers certification for photogrammetric technologists, remote-sensing technologists, and Geographic Information System/Land Information System (GIS/LIS) technologists. The National Society of Professional Surveyors offers the Certified Survey Technician credential.
With many years of experience and formal training in surveying, surveying technicians may advance to senior survey technician, then to party chief. Depending on state licensing requirements, they may be able to become licensed surveyors.
