By ZipRecruiter Marketplace Research Team

A mapper can describe a data mapper as well as a person who creates geographic maps. A data mapper uses various software programs to extract data from a database, convert it, and load it into another database to analyze and glean insights into business analytics. Duties of a geographic mapper or mapping technician include gathering and processing geographical data to create a map of an area. They work with specialists such as surveyors and cartographers using specialized tools to create precise, accurate maps.

A mapper works with surveyors using various equipment and tools to create a map of an area. It is possible to obtain a position with just a high school diploma and hands-on experience, but earning a certificate or associate degree in GIS (geographic information systems) is advisable. There are also four certification levels available through the National Society of Professional Surveyors which would make you more valuable to a potential employer. Responsibilities include recording data with GPS, GIS, and CAD software. Teamwork is important, as is some measure of physical fitness as you often work outdoors and frequently shift locations. A surveyor has similar required qualifications, but must also have special state licensing such as the PSM license, and surveyors often record more detailed information.

A geographic information system (GIS) mapper, or GIS technician, interprets maps, manages GIS databases, and provides insight into digital land data. To be a GIS Mapper, you must have a bachelor’s degree in computer science or geography, with course experience in GIS, geography, and related subjects. A master’s degree may increase your job prospects and salary potential, though it is not a requirement. As a GIS mapper, you should have superb attention to detail when entering data into software programs, as well as written and verbal communication skills for producing and presenting reports, and possibly training others.

A mapper in computer programming deals with databases–extracting data and providing analytical, evidence-based insights to help business improve operational efficiency. As a data mapper, you use common data integration and storage processes like ETL (extract, transform, load) and EDI (electronic data interchange), to create insights into business and organizational processes, allowing organizations to understand extremely complex systems like global shipping and finance structures, and to make intentional changes to increase efficiency at a macro level.
