Maps that help transit riders get "there"

August 25, 2014

The motto of King County Metro Transit is “We’ll Get You There.” Maps are all about where “There” is, and Metro uses maps extensively, both internally and for customer information, including places where riders may need them the most—in kiosks located at transit centers and bus stops throughout the Metro service area. But developing and maintaining kiosk maps for Metro, the nation’s 8th-largest public transit agency, is a complex endeavor. In 2012 Metro Transit enlisted the King County GIS Center to help in the effort, and specifically to rethink and redesign its system-wide kiosk map—to find ways to make it more readable and useful, as well as easier to update.

Lidar Swipe map viewer unveiled

With the Lidar Swipe map viewer users navigate to a portion of the county and ‘swipe’ a bar or spyglass on the computer screen to view either the aerial photography or the shaded-relief ground image for the selected area.

Founded in 2012 by long-time educator and strategic storyteller, Peter Donaldson, Sustainability Ambassadors is an innovative youth leadership program training exceptionally self-motivated young people (ages 13-21) as skilled ambassadors capable of tracking and communicating improvements in sustainable community conditions across generations and community sectors.
