Key Facts & Information

Overview Have you ever been in a new city and needed to figure out how to get from point A to point B? Have you ever tried to figure out the best time of the year to go on vacation so that you have good weather? Many people in these situations turn to a map. Maps are important sources of information, and geographic information systems (GIS) technicians are the professionals who gather data from a variety of sources, store it in databases, and use those databases to make accurate maps. Because maps are used to convey all kinds of information, such as rainfall density or traffic patterns, GIS technicians must be knowledgeable in many different areas of science.

Training, Other Qualifications

GIS technicians should continue to take classes and participate in professional seminars in order to keep current in new technologies and practices in their field.

Education and Training

The minimum degree required to gain an entry-level position as a GIS technician is a bachelor's degree in geographic information systems, geography, cartography, or related field. Candidates who have internships in cartography or GIS, or who have experience with mapping or surveying, have an edge when seeking employment.

In this video, GIS analyst Josi Jenneskens explains that she pursued her interest in GIS because of her love of art and travel. She likes the creativity involved in making maps that help people make decisions and draw conclusions.

Nature of the Work

Geographic information systems (GIS) technicians are professionals who convert the information found in topographical maps, geographical surveys, satellite images, fieldwork, and other sources into data that is correlated to location. Because GIS technicians work with organizing and storing large amounts of data, they design and develop databases to house data. They work with scientists and clients to update GIS databases and analyze the data to find out how geographical elements relate. GIS technicians develop computer programs for their employers or clients that query GIS systems for pertinent data and correlations. They can also train their clients to use the computer programs or tools that they create. GIS technicians physically make maps to share the data that they have collected, either from the field, or from querying GIS systems. They share these maps with their employers and their clients.

GIS technicians work on projects across a wide spectrum. For example, GIS technicians are involved in creating navigation systems, real-estate mapping, military surveillance, and site selection for buildings. In order to be able to do their job well, GIS technicians must be familiar with GIS software and hardware tools. GIS technicians must be proficient at drafting, computer-aided design and drafting (CADD), SQL language, and ArcGIS (a suite of GIS software). They use large-format printers, scanners, and plotters.

Work Environment

GIS technicians are usually employed in clean, well-lit, and well-ventilated offices. They work with computers and automated mapping equipment. The work often involves long hours in front of a computer screen, using a keyboard and a mouse. Some GIS professionals collect data via fieldwork outdoors. GIS technicians generally work 40 hours a week. Longer hours and workweeks are not uncommon.

GIS technicians are employed in a variety of industries including the private sector, the military, and the federal government.

On the Job

  • Design or coordinate the development of integrated GIS spatial or non-spatial databases.
  • Design or prepare graphic representations of GIS data using GIS hardware or software applications.
  • Enter data into GIS databases using techniques such as coordinate geometry, keyboard entry of tabular data, manual digitizing of maps, scanning or automatic conversion to vectors, and conversion of other sources of digital data.
  • Maintain or modify existing GIS databases.
  • Perform geospatial data building, modeling, or analysis using advanced spatial analysis, data manipulation, or cartography software.
  • Analyze GIS data to identify spatial relationships or display results of analyses using maps, graphs, or tabular data.
  • Interpret aerial or ortho photographs.
  • Review existing or incoming data for currency, accuracy, usefulness, quality, or completeness of documentation.
  • Transfer or rescale information from original photographs onto maps or other photographs.
  • Select cartographic elements needed for effective presentation of information.
  • Confer with users to analyze, configure, or troubleshoot applications.
  • Read current literature, talk with colleagues, continue education, or participate in professional organizations or conferences to keep abreast of developments in GIS technology, equipment, or systems.
  • Provide technical support to users or clients regarding the maintenance, development, or operation of GIS databases, equipment, or applications.
  • Recommend procedures and equipment or software upgrades to increase data accessibility or ease of use.

Do you ever wonder how pirates sailed the seven seas? The two most important things a pirate could have (besides a parrot and big hat) were a compass and an accurate watch. Ancient navigators didn't know about compasses, so how did they know where they were going? Could they have used the stars to know which way to go? Read more

Extinct might be a word you associate with animals that lived long ago, like the dinosaurs, but did you know that over 18,000 species are classified as "threatened" (susceptible to extinction) today? Scientists involved in wildlife conservation have a tough job; they are in charge of determining what needs to be done to prevent a species from becoming extinct. Habitat, food supply, and impacts of local human populations are just a few of the factors these scientists take into account. It is a… Read more

We rely heavily on our senses to tell us about our environment. But in addition to the senses of touch, smell, taste, hearing, and sight, some animals are able to sense Earth's magnetic field. Migratory turtles and birds use this sense to guide them on long journeys. Homing pigeons use it to find their way home. New research suggests that large mammals, such as cows and deer, may also have the ability to sense the direction of magnetic north. In this animal behavior science project, you will… Read more

Have you ever gone camping, looked up at the stars, and found the Big Dipper? Two stars in the dipper part of this constellation point to Polaris, the north star, which people have used for thousands of years to help them find their way. In this plant biology science fair project, you'll investigate whether plants, like moss, can help you find your way, too. Read more

This is a great science fair project for someone who is interested in both mathematics and art. Spidrons are geometric forms made from alternating sequences of equilateral and isosceles (30°, 30°, 120°) triangles. Spidrons were discovered and named by Daniel Erdély in the early 1970's, and have since been studied by mathematicians and artists alike. This project is a great way to learn about the mathematics and art of tiling patterns. Read more

The Sun is the ultimate source of the energy that powers weather systems on Earth. Geomagnetic storms are sun-powered storms in the upper atmosphere, arising from energized particles that are periodically ejected by the Sun. Among other effects, geomagnetic storms can wreak havoc with earth-orbiting satellites, and disrupt satellite communications. The global positioning system (GPS) is a network of 24 earth-orbiting satellites that constantly sends radio signals through the earth's… Read more

How is geology important for our energy resources? Coal, oil, and natural gas are formed by geological processes over millions of years. Certain geological formations can indicate a reservoir of coal, oil, or natural gas. Also, geothermal processes can be used as an energy resource. How are these formations identified? How are the resources extracted? You can use the National Geospatial Program to access, view, and download information from geospatial databases containing a broad spectrum… Read more

What do knots, maps, mazes, driving directions, and doughnuts have in common? The answer is topology, a branch of mathematics that studies the spatial properties and connections of an object. Topology has sometimes been called rubber-sheet geometry because it does not distinguish between a circle and a square (a circle made out of a rubber band can be stretched into a square) but does distinguish between a circle and a figure eight (you cannot stretch a figure eight into a circle without… Read more
