Job description
Technicians produce data layers, maps, tables, and reports using spatial analysis tools, and enter new information into GIS databases through methods like coordinate geometry, manual digitizing, or converting scanned and digital sources into usable formats. Some roles lean more technical, involving programming and software development to maintain or improve existing GIS systems, while others focus on producing graphics or providing direct technical support to clients. Precision matters throughout, since flawed spatial data can throw off everything built on top of it, from city planning to environmental research.
Pros
- High upside earning potential, up to $188k
- Much faster than average projected job growth (8.2% over the next decade)
- Only vocational training, apprenticeship, or an associate's degree is required, not a four-year degree
Cons
- Above-average hours (40-50/week) during data deadlines or large mapping projects
- Precision and accuracy are essential when building and maintaining spatial databases
- Work is desk-bound and screen-heavy, with less field time than the source data might suggest
A typical day
The morning ticket queue sets the agenda: the public works department needs every storm drain in three districts added to the utility layer, so the technician spends two hours digitizing from field GPS files and orthophotos, attributes entered to the data standard. Midday brings a data surgery job — two address databases that disagree, reconciled with geocoding runs and a scripted cleanup that saves a week of hand edits. The afternoon is map production: a council-meeting exhibit styled clearly enough for non-experts, then a field check where the tech collects six missing hydrants with a GNSS unit. The database is the product; the maps everyone sees are just its reflection.
Tasks at the job
- Produce data layers, maps, tables, or reports, using spatial analysis procedures or Geographic Information Systems (GIS) technology, equipment, or systems.
- Design or prepare graphic representations of Geographic Information Systems (GIS) data, using GIS hardware or software applications.
- Maintain or modify existing Geographic Information Systems (GIS) databases.
- Provide technical expertise in Geographic Information Systems (GIS) technology to clients or users.
- Perform computer programming, data analysis, or software development for Geographic Information Systems (GIS) applications, including the maintenance of existing systems or research and development for future enhancements.
- Enter data into Geographic Information Systems (GIS) databases, using techniques such as coordinate geometry, keyboard entry of tabular data, manual digitizing of maps, scanning or automatic conversion to vectors, or conversion of other sources of digital data.
Workplace & working conditions
Work happens indoors in a climate-controlled setting, and most of the day is spent sitting at a desk.
There's a regular, moderate amount of time pressure, and you're expected to exercise significant independent judgment day to day. Precision and accuracy are essential to the work.
