Stell leverages and integrates computer-aided design, Geographic Information Systems, and Global Positioning System technology directly into project work. These individual processes can be used as interconnected, cross platform, communicative, and flexible tools with centralized storage. Our GIS services cut across our business lines to provide our partners and clients with lifecycle data management, analysis, and display capabilities unique to each project. Accurate, reliable geospatial information is created from the methodical application of GIS processes, procedures, and techniques across multiple organizations and disciplines. GIS technology is an essential tool we use to accurately assess potential project logistics and scope, provide project level mapping support, conform open sourced and proprietary data to fit client GIS submission standards or needs, collect localized or on site data, and display tabular or narrative data in a pictorial manner.


Successful Projects: 

Adams Avenue Connector Environmental Justice (EJ) Analysis, Philadelphia, PA (Pennsylvania Department of Transportation – PennDOT)

Stell completed an EJ analysis to supplement the Adams Avenue Connector project. Our GIS staff collected appropriate Census data to identify EJ populations, identify potential effects, and determine if those effects have a disproportionate effects on EJ populations. This involved reviewing guidance documents published by PennDOT and complying with federal regulations regarding construction and federal funds.


Drinking Water and Storm Water Protection Plans Services (U.S. Army)

Stell was responsible for storm water and drinking water sampling and assisted with Storm Water Pollution Protection Plans. Before field efforts began, our GIS staff obtained LIDAR-based elevation data and constructed localized contour profiles that were more detailed than any contour data publicly available. This allowed our environmental scientists and engineers to model water flow across each site. Additionally, we used Trimble GPS units to collect relevant data on site, which were used to create tables and maps for project deliverables.


Archaeological Surveys, Fort Bliss, TX (U.S. Army)

In support of this multimillion dollar cultural resources effort, our GIS staff designed data collection workflow consisting of numerous field staff collecting data with Trimble Geo XH 6000, backing up field data daily to a centralized database that automatically processes raw data to a Spatial Data Standards for Facilities, Infrastructure, and Environment-based geodatabase. Data were initially provided via GIS format to outline survey extents and boundaries. From those boundaries and GPS data collection, Stell inventoried all findings and constructed new survey boundaries. Field data also were used for mapping within deliverables.bliss-figure-5-archaic-points
