Greenman-Pedersen, Inc. (GPI) supported the City of Rochester, NH with their ADA Transition Plan by using GIS to coordinate desk review, field data collection, and deficiency analysis. This session walks through the GIS-led workflow that supported the Project Manager and engineers from kickoff to final report and data delivery. Early communication aligned office and field staff on ADA review criteria and how data would be collected, accessed, and evaluated. Using municipal datasets as a foundation, GPI implemented a standardized schema with ADA-specific attributes for sidewalks, crosswalks, curb ramps, pedestrian access buttons, and traffic signals. A combination of ESRI-based desktop and web GIS supported all aspects of the project, allowing deficiencies to be identified, symbolized, and filtered without duplicative workflows while producing the final report and a comprehensive database deliverable to the City.
