The most important qualifications needed for a geographic information systems (GIS) job are a strong working knowledge of GIS and excellent computer skills. An associate or bachelor’s degree in GIS is often necessary, although many GIS workers come into the field with an industry-specific degree, such as geology or civil engineering, and certifications in GIS. Other useful qualifications include strong communication skills and the ability to work as part of a large team of surveyors, analysts, and technicians.
