What GIS & Environmental Management Technologies does

GIS & Environmental Management Technologies, LLC (operating as GEM Technologies) is a privately held, woman-owned small business headquartered at 5998 Bethany Road in Mason, Ohio. Founded in 2009 and led by President Jim Erjavec alongside CFO/Co-Owner Nina Erjavec, the firm delivers GIS (Geographic Information Systems) and environmental/geological consulting services to government agencies, transportation planners, academic researchers, and private-sector clients. Service delivery extends across at least seven U.S. states, including Ohio, Montana, Connecticut, North Carolina, Kentucky, Wyoming, and Washington. The company has produced notable geological visualizations such as the Camas Prairie Giant Ripples and Glacial Lake Missoula reconstructions for the Montana Department of Transportation, and peer-reviewed research on Pleistocene proglacial lakes in the Ohio Journal of Science.

The company's core technical offering revolves around GIS design, development, and analysis applied to environmental and geological datasets. Core product lines include GIS & Imagery, GIS & Geological Analysis, GIS & Data Analysis, GIS & Mapping, 3D Modeling using Digital Elevation Models, and time-dependent GIS Animations. Complementary consulting services cover environmental and geological investigations, spatial analysis, time-dependent data analysis, and custom spatial database design and management. The firm's differentiator is the integration of GIS production capabilities with domain-specific environmental and geological consulting expertise, delivered as publication-ready outputs rather than raw analytical work.

The business model is direct consulting engagement: services are sold one-on-one to clients (predominantly government agencies) with no publicly disclosed pricing, no packaged SaaS offering, no app or API surface, and no documented marketing budget. Lead generation runs through the company website (hosted on WordPress since 2016) and direct outreach to the President. With a headcount of 1-10, no disclosed funding, no patents, no certifications, and no subsidiary structure, the firm operates as a boutique consulting practice whose economics are tightly coupled to a small number of project engagements and the personal production capacity of its principals.

Direct peers

• Woolpert: Architecture, engineering, and geospatial (AEG) firm with a strong GIS and remote sensing practice serving government and infrastructure clients. Directly comparable in that both firms sell GIS/environmental consulting to state agencies, with Woolpert operating at much larger scale.
• RESPEC: Geoscience, engineering, and technology consulting firm combining geology, GIS, and data analytics for government and resource clients. Closely comparable niche to GIS & Environmental Management Technologies, particularly in geological interpretation and geospatial analytics.

Broad incumbents

• Kleinfelder: Engineering, environmental, and infrastructure consulting firm with GIS capabilities supporting DOTs, utilities, and federal agencies. Comparable service overlap in environmental assessment and geospatial mapping, though at substantially larger scale.
• Michael Baker International: Engineering, consulting, and geospatial services firm serving DOTs, federal agencies, and infrastructure owners. Overlaps directly in GIS mapping, environmental analysis, and transportation planning—markets where GIS & Environmental Management Technologies has won work.
• Tetra Tech: Global environmental and engineering consulting firm with extensive GIS and geospatial analytics capabilities. Competes for the same federal/state environmental and infrastructure contracts, though from a much larger scale and broader portfolio.
• AECOM: Global infrastructure consulting firm with a large environmental services and GIS practice serving transportation, water, and federal clients. Pursues many of the same government opportunities as GIS & Environmental Management Technologies, with significantly greater resources.
• Stantec: Environmental services, engineering, and geospatial consulting firm with active GIS practice supporting DOTs, municipalities, and federal agencies. Service overlap in environmental consulting and GIS mapping for infrastructure and planning clients.
• ERM (Environmental Resources Management): Global environmental consulting firm with significant GIS and geospatial analytics capabilities supporting site assessment, permitting, and impact analysis. Comparable in environmental consulting services, though primarily serves larger enterprise and industrial clients.
• Gannett Fleming: Engineering and infrastructure consulting firm with a dedicated geospatial division (GeoDecisions) offering GIS services to DOTs and government clients. Directly comparable in GIS-for-transportation consulting and competes for similar state agency engagements.

Others

• Esri: Dominant GIS software platform provider (ArcGIS). Not a direct competitor but a key enabling technology vendor whose platform ecosystem defines the tooling upon which GIS & Environmental Management Technologies builds its consulting services.
