Prior to this position, she served as a GIS Professional within the Agency of Agriculture, Food and Markets (VAAFM). Here, she provided ad hoc GIS and data visualization support for several divisions within VAAFM. Chaveli received her bachelor’s degree in Geography and Environmental Studies from Colgate University in 2019. She became interested in the public sector through a post-grad internship with Audubon Vermont where she learned about state-level environmental policy and sustainable forest management. In addition to maps, Chaveli enjoys rock climbing, bird watching, and cooking.


Steve Fugate

Mr. Fugate is responsible for the stewardship and development of Vermont’s Lidar-based elevation assets as VCGI's Lidar Program Manager. He strives to stay on the forefront of GIS technology where he works to build collaborative partnerships and implement innovate solutions around the use of Lidar.

Mr. Fugate has used GIS since 2007 for fine-scale vegetation mapping, invasive plant inventories, environmental response planning, change detection mapping, digital forest restoration, and more. He is dedicated GIS practitioner and is honored to join the VCGI team and serve the great state of Vermont. In his free time, Mr. Fugate enjoys spending time in the great outdoors with his family and friends.

Mr. Fugate received a B.S. in Natural Resource Management from Colorado State University, a Graduate Certificate in GIS from Northern Arizona University, and in 2022 a Graduate Certificate in Geospatial Programming and Web Map Development from Penn State World Campus.


Dylan Broderick

Dylan joined VCGI in 2022 as part of the Vermont Parcel Program. She has a strong interest in creating and maintaining spatial data that are user-friendly, accessible, and informative. She has always been drawn to maps and the diverse, unique ways they can share and spread information.

Dylan holds Bachelors and Masters degrees in GIS from Clark University, where her research combined remote sensing and field data to estimate belowground carbon storage in northeast Siberia. Prior to VCGI, Dylan worked in environmental consulting to provide GIS support on projects concerning site investigation and remediation. She earned her Geographic Information Systems Professional (GISP) certification in 2021. She enjoys spending her free time outside, particularly running, skiing, or hiking.


Ivan Brown

Ivan joined VCGI in September 2012 to accept an array of responsibilities, including responsibilities in the areas of Project Management, Database Administration, and Web-Service Administration. He is currently VCGI’s GIS Database Administrator.

Ivan has been expanding experience in the GIS field since 1998. Prior to joining VCGI, he served in GIS programs within local government for 14 years. His extensive experience includes work in many functions, including data collection, quality control, spatial analysis, application development, technical communication, and enterprise-geodatabase administration. Over the course of his tenures in local government, he plied his skills in all areas of local government, including Public Safety, Emergency Management, Urban Forestry, Public Works, Utilities, Customer Service, and Economic Development to name a few.

Ivan holds a B.S. degree in Business Administration with a concentration in Economics from Christopher Newport University. He majored in Business Administration because of its interdisciplinary quality. He enjoyed studying geographic information during his senior year when conducting research on the economics of urban transportation. After graduation, Ivan researched various career paths that might be taken. He discovered GIS. Given that he had always liked maps, had enjoyed the geographic component of his senior-year research, and knew that GIS was increasingly used to serve business needs, he decided to take the “GIS Road”. He took a course in GIS Management and entered the GIS workforce.


Tim Terway

Tim is VCGI's point of contact for users and creators of our geospatial information. He is responsible for coordination and knowledge sharing activities, as well as for advancing the design and use of VCGI's data products and services.

Daniel Jarvis

Daniel is VCGI's embedded GIS Manager for the Vermont Department of Health and other Departments within the Agency of Human Services, managing day to day GIS operations for all Health Divisions, and assisting Human Services employees with GIS and Spatial Analysis. Daniel has been in State Government since 2014, and has been in the business of GIS since 2004. Daniel holds a Masters and PhD in Geography from Clark University, where Daniel studied spatial and temporal patterns of forest change using spatial statistical and GIS methods.

Daniel loves to take on new hobbies and find excuses to be outside. Hellbrook trail is a summer favorite. Gotta get to the top in less than an hour!


Rhiannon Killian

Since 2020, Rhiannon has been honored to serve Vermonters by assisting the VCGI and the Vermont Department of Health report health data. 

Broadly interested in all sciences, Rhiannon started her career researching, collecting, analyzing and presenting biomedical laboratory data.  Once she learned of the potential of GIS to store, manage, analyze, and present any type of location-based data, she recognized both the wide applicability and interdisciplinary nature of the field and the potential to more directly and immediately serve the needs of the public.

In 2020, Rhiannon rounded out her B.S. in General Science and Anthropology (Penn State) and PhD in Biomedical Sciences (University of California - San Diego) with an A.S. in GIS from San Diego Mesa College, where she interned with the City of El Cajon and the geospatial firm PanGIS. When away from her work station, she enjoys crafts, hiking and exploring archaeological sites.
