Three Rivers Heritage Trail

A cutting-edge survey of the City of Pittsburgh's river trail system conducted by land, river, and air, delivered in an interactive web viewer

CivicMapper teamed with evolve, the City of Pittsburgh, and Nodeology to provide mapping and web app development support for the City’s Three Rivers Heritage Trail Maintenance and Management Plan. The overall goal of this project was to help the City create a plan for maintaining and managing the Three Rivers Heritage Trail, a 26-mile trail network within the City that runs adjacent to our three rivers. The trail is an important infrastructure asset to Pittsburgh, for pedestrians and bikers who use the trail for commuting and leisure.

To support the project team who were working on the trail assessment, CivicMapper mapped existing trail segment data as well as created new data to better understand the current trail conditions. This included drone aerial photography which was used to assess canopy cover, and continuous 360camera photography of the trail which was used to assess ecology (invasive species), trail lighting, and trail condition. The aerial images were stitched together along the trail to show an updated overhead detailed view of the trail segments, and the 360 camera photos were assembled into a video-like dataset that was dynamically linked to the map of the trail. And ArcGIS Online web app was created for the project team so they could locate discrete points along the trail and cross-reference their field assessments.

CivicMapper also developed a web map for the client that features trail segment scoring, showing which areas of the trail require more immediate attention for maintenance and management. The trail is scored based on a function of canopy cover, an engineering assessment, and an ecological assessment.
