GIS stands for geographic information systems. GIS technicians create maps and custom GIS software or applications for a variety of purposes. As a GIS technician, you interpret maps, manipulate digital land data, and manage the information entered in your GIS database. A GIS technician may advance into a cartographer position after a few years in the technician role. Some of your responsibilities may include data modeling, inputting and updating data, analyzing spatial or topographical data, and managing geographic data. In essence, a GIS technician administers a database but does not use the data they administer. Instead, you hand it off to others on your team.
