GIS is a powerful tool for planning and managing trails. Many efforts to build comprehensive trail databases are currently underway around the country. Two Pacific Northwest organizations discuss how they approached the task of developing their GIS databases. Metro, the Portland-area regional government, designed and built a database for over 3,000 miles of trails, while the State of Washington is currently building a standardized database for approximately 11,000 miles of trails.

Jenny Konwinski is the GIS Technical Lead for the Washington Statewide Trails Project and has been involved with the effort since April 2014. She has been working with GIS and related technologies since 1994. She has provided computer mapping and analytics support in the water and biological resources management fields and in local government and education initiatives in Florida and North Carolina. Jenny and her husband enjoy exploring Washington's amazing trails whenever they can and look forward to hiking and biking many more in the future!

Reid Ammann has been working on the Washington State Trails Database Project since it began in January of 2014. While taking night classes for GIS at the University of Washington, Reid and his classmate were offered a chance to start up the proposed Trails Database project. When the project got funding 6 months later, he joined the team as a part time data analyst. He is now working on the project full time as well as leading a similar project with a group of UW students building a trailheads database. After graduating from the University of Washington with a business degree, Reid was first introduced to GIS working as crew leader in the Nevada Conservation Corps building hiking trails in the backcountry. In between teaching English in South Korea and Chile, Reid took a GIS introduction class, which qualified him for the year-long certificate program where he began working on the Trails Project.
