Unveiling the Essential Components of Geographic Information Systems
The U.S. infrastructure landscape continues to grow and is increasingly focused on operating and maintaining existing transportation and water infrastructure systems, especially at the state and local levels. In this rapidly evolving category, Geographic Information Systems (GIS) has become an indispensable tool for civil engineering companies. By integrating spatial data with advanced analytics, GIS helps engineers to make informed decisions that enhance project efficiency and sustainability. At Pape-Dawson, our GIS services are at the forefront of this transformation, allowing us to deliver innovative solutions across various sectors and revolutionize data-driven decisions for our clients.
Why GIS Matters for Today’s Infrastructure Projects
GIS plays a key role in today’s infrastructure development by providing spatial context for complex datasets, offering clarity in areas like transportation upgrades, flood mitigation, and utility planning. By combining hardware, software, data, and expert interpretation, GIS enhances the way projects are planned, designed, and delivered. For example, on a TxDOT Statewide ADA Data Collection project, we used GIS-based web and mobile applications to map, collect, and analyze thousands of pedestrian-related assets across the state. Our efficient approach led TxDOT to expand our scope from 8 to 13 districts, spanning 125 counties. This project shows how GIS can improve data quality, accelerate timelines, and help agencies prioritize infrastructure upgrades for communities with the greatest need.
The Five Essential Components of GIS
Understanding the core components of GIS is crucial for leveraging its full potential. These components work synergistically to collect, analyze, and visualize spatial data.
Hardware. Hardware forms the backbone of any GIS, encompassing the physical devices required to collect and process spatial data. This includes high-performance servers, GPS units, drones, and mobile devices. At Pape-Dawson, we use advanced UAVs with LiDAR to collect highly accurate topographic data, significantly reducing the time and resources needed for field surveys.
Software. Tools like ArcGIS are vital for visualizing, analyzing, and sharing data. Our teams create interactive dashboards that allow real-time project monitoring, boosting transparency and efficiency. These dashboards are particularly valuable in managing complex projects through our GIS Technologies and Services practice area.
Data. Data is the most critical component of GIS, combining both spatial features (terrain, roads, or flood zones) and attribute information (soil type, land ownership, or population density). On Harris County Flood Control District’s MAAPnext program, Pape-Dawson, in conjunction with FEMA, developed peer-reviewed 1D/2D watershed-wide models and maps of existing creek conditions for three different creeks. Our role in modeling the different watersheds was to calibrate hydrology and hydraulics against historical events, including Hurricane Harvey, to develop updated regulatory FEMA products at a high level of detail.
People. Technology is only as powerful as the people behind it. Our multidisciplinary teams include GIS analysts, civil engineers, and environmental scientists who work together to transform raw data into actionable insights. This collaborative approach ensures that projects are not only technically sound but also environmentally sustainable and socially responsible.
Methods/Workflows. Consistent methods ensure accuracy and reliability in GIS applications. At Pape-Dawson, we have developed proprietary workflows that streamline data collection and analysis, enhancing project delivery timelines. Our approach to utility routes, easements, and right-of-way surveys exemplifies how structured methodologies can optimize project outcomes.
How GIS Reveals Hidden Opportunities
One of the most powerful aspects of GIS is its ability to uncover what’s not immediately visible. By layering various datasets, such as topography, infrastructure, zoning, and environmental factors, GIS uncovers patterns, identifies risks, and highlights areas of potential growth or concern.
As the need for new and updated infrastructure grows, Geographic Information Systems (GIS) has become an indispensable tool for the success of any civil engineering company or design firm.
