Rails-to-Trails Conservancy (RTC) represents a compelling GIS use case involving the systematic identification, mapping, and conversion of abandoned railway corridors into public recreational trails and greenways. As a nonprofit organization dedicated to transforming disused rail infrastructure into connected trail networks, RTC relies heavily on geospatial data management, spatial analysis, and digital mapping technologies to advance its mission effectively.

From a GIS perspective, this use case encompasses multi-layered spatial datasets including historical railroad alignments, land ownership parcels, right-of-way boundaries, terrain elevation models, and adjacent land use classifications. Geospatial analysts leverage tools such as ArcGIS, QGIS, and remote sensing platforms to assess corridor feasibility, identify connectivity gaps, and prioritize acquisition targets across diverse jurisdictions.

Practical GIS applications include network analysis for trail connectivity modeling, proximity analysis to measure access equity in underserved communities, and spatial overlay techniques to evaluate environmental constraints or sensitive habitat zones. The resulting geospatial intelligence supports informed decision-making for planners, policymakers, and conservation advocates. Ultimately, this use case demonstrates how robust GIS methodology transforms complex infrastructure data into actionable strategies for sustainable community development and recreational planning.
