Caitlin Willoughby

GIS Specialist

Caitlin Willoughby is an environmental geospatial/National Environmental Policy Act (NEPA) professional with more than twenty years’ experience in technical, analytical, and geospatial project experience, respected for her analytical, research, and communication skills, and attention to detail. She is knowledgeable in all aspects of planning for and applying environmental and geospatial science technologies, from problem identification, requirements gathering, methodology, analysis, results evaluation, cartography, and other visual communication. Willoughby has experience in planning and helping to develop custom geospatial solutions for analyses and visualization, including storymaps, dashboards, data management, data creation and manipulation, and cartographic solutions for environmental and NEPA support.

Willoughby has been at the U.S. DOT Volpe Center since 2021, providing geospatial analytical and technical support, program management, and environmental support to the FAA, FMCSA, the Federal Permitting improvement Steering Council (FPISC), FHWA, and National Park Service. She leads GIS support to the FAA’s Unstaffed Infrastructure Sustainment (UIS) Program, where she oversees the effort to update all Air Traffic Operations National Airspace System facilities across the country in the Geospatial Event Management System (GEMS) hosted within the FAA’s firewall. This effort has seen ~90% verification of ATO facilities via latitude and longitude locations using authoritative data and imagery to validate the site. GEMS is being used as the latitude and longitude database for many other FAA databases, including the Facility Service and Equipment Profile (FSEP), which now hosts GEMS’ lat/longs. This effort has been a long time coming and she is happy to have been a part of this important work!

Prior to joining the U.S. DOT Volpe Center, Willoughby was a contractor with Booz Allen Hamilton for 17 years, providing project management and technical environmental, geospatial, and NEPA support for many federal agencies, in both defense (e.g., Army, Air Force, Marine Corps, Navy, OSD) and civil government (e.g., BLM, DOT, EPA, FAA, NPS). Before Booz Allen, she worked as a GIS/Information Scientist at a non-profit environmental breast cancer research organization, Silent Spring Institute. There, she helped research and analyze geospatial data for environmental factors and breast cancer incidence.
