Geographic Information Systems (GIS) is a vital component of the planning process. It helps planners organize, interpret, and visualize information in ways that facilitate clearer thinking and informed decision-making.
Here are five ways GIS supports more innovative community development.
- Understanding Context Through Spatial Layers
Long-range planning explores land use, traffic counts, transit access, broadband coverage, flood zones, and demographic information. When viewed together as layers on a map, a more complete picture of a place emerges. This context helps planners see relationships, anticipate challenges, and identify opportunities that may not be obvious through raw data alone.
- Making Land Use More Strategic
GIS is beneficial when addressing questions related to land use. It can reveal where development pressure is growing, where infrastructure already exists, or where zoning is out of alignment with community goals. These insights help guide rezoning efforts, support housing strategies, and identify sites for redevelopment. With GIS, land use planning becomes more intentional and better supported by data.
- Planning for Transportation and Access
Geography, behavior, and policy shape transportation systems. GIS helps bring these elements together. Planners can use these maps to identify areas where traffic congestion occurs, areas with missing sidewalks, and the level of service provided by public transportation in different neighborhoods. Communities can utilize these insights to enhance connections, improve safety, and design systems that help people get where they need to go safely and efficiently.
- Addressing Environmental Conditions
Planning with the environment in mind requires accurate and reliable information. GIS helps track flood-prone areas, map tree canopy coverage, model stormwater runoff, and assess heat vulnerability. It can demonstrate when and where community standards need to be updated to mitigate development projects. When used early in the planning process, this information can shape decisions that are more resilient and less reactive.
- Communicating More Clearly with the Public
Maps remain one of the most accessible ways to share planning information due to their visual nature. GIS can go beyond static maps by creating interactive, user-friendly maps tailored to a local audience or decision makers. These tools can display zoning updates, future land use plans, and project timelines, among other things, enabling communities to understand proposals and their implications. Sharing information this way also improves understanding, encouraging better dialogue and public feedback.
A Useful Tool for Complex Work
GIS is not a replacement for judgment or experience. What it offers is structure, clarity, and a more impactful way to understand community data. In an area where small choices often have long-term effects, this kind of clarity is invaluable.
Planning for the future means designing with the best tools available. GIS is one of them.
