GIS Specialist

Technology & Design

Works with the spatial data a Surveyor and Drone/UAV Specialist collect, turning raw location data into the maps and analysis a project actually uses.

What is a GIS Specialist?

A GIS (Geographic Information Systems) Specialist manages and analyzes spatial data, turning survey data, drone-captured photogrammetry, and utility records into usable maps, site analyses, and asset databases. A Surveyor collects precise field measurements and a Drone/UAV Specialist captures aerial data; a GIS Specialist is often the person who takes that raw data and layers it with other spatial information (zoning, utilities, floodplains, existing infrastructure) to support planning, permitting, and asset management decisions.

What they do

• Build and maintain GIS databases of site, utility, and infrastructure data
• Process survey and drone-captured spatial data into usable maps and models
• Perform spatial analysis to support site selection, permitting, or asset management decisions
• Create maps and visualizations for project teams, clients, and public agencies
• Integrate GIS data with BIM and other project management systems
• Maintain data accuracy and update GIS layers as a project or facility changes

• 11:30 AMPerform a spatial analysis identifying floodplain overlap for a proposed site
• 1:30 PMBuild a map visualization for a client presentation on site conditions
• 3:00 PMCoordinate with a surveyor on integrating new field survey data into the GIS system

Pay expectations

Reviewed May 2025. GIS Specialist is typically reached through promotion or years of experience in a related role, not a day-one starting point, so this chart shows the pay range for people already working as a GIS Specialist rather than entry-level pay. "Lower range" is the lower part of the national wage distribution for this occupation, "typical" sits around the national median, and "top of scale" is the upper part, since pay isn't actually tracked by years on the job. Real pay varies a lot by state, metro area, union status, and employer, so scale these up or down for your market.

Education

Required:

A bachelor's degree in GIS, geography, surveying, or a related field; no license is legally required for this role

Preferred:

GISP (GIS Professional) certification from the GIS Certification Institute, which requires at least four years of professional experience, a portfolio review covering education and professional contributions, and passing the GISCI Core Technical Exam

Not necessary:

A civil engineering or surveying license; GIS work itself isn't a licensed profession the way surveying or engineering is
