California, United States
Summary
👤
Senior🎓
Top SchoolMarshall Ballard is a Supervising Transportation Planner and interdisciplinary geographer with 25+ years of practice applying GIS, remote sensing, and spatial analytics to transportation, environmental planning, and community engagement. He builds multimodal, data-driven solutions—from origin/destination analysis and real-time transit feeds to managed-lanes specifications—and has a track record of liberating siloed data to inform policy and operations. Marshall has led enterprise GIS strategy and implementation across agencies and consulting firms, integrating cloud GIS, open-source tools, and web services to reduce costs and scale delivery. He coaches and mentors GIS teams, ran GeoSpatial business development at Ironwood, and contributed to national GIS governance through TRB committee work. Based in California, he pairs technical chops in spatial modeling and big-transit data with practical program delivery, including pioneering managed/tolled lanes and open transit deployments. An unexpected thread across his career is hands-on environmental fieldwork and aquaculture experience, which informs his pragmatic, ecosystem-aware approach to planning.
