Mapping Roads on Santa Catalina Island
Santa Catalina Island needed a new road map. Existing maps were not only incomplete—at times, they were just plain wrong, often showing the same road in different locations as much as a mile apart.
Los Angeles County's Fire, Baywatch, and Sheriff departments believed it was only a matter of time before the wacky maps sent rescue crews on a wild goose chase, risking human life and property damage. Together with the Santa Catalina Island Conservancy (SCICo) and the city of Avalon, they decided to create an accurate, comprehensive map that would enable emergency response crews to do their jobs effectively.
Using a GPS Pathfinder® Pro XR receiver and software which Trimble had donated to the SCICo geographic information system (GIS) program, SCICo President Bill Bushing and conservancy rangers Jim Fellows and Bob Kopolow mapped 240 miles of the island's interior roads with an estimated accuracy of 2-3 feet. The Conservancy later imported the GPS data to its GIS where it was used to develop a road use and maintenance plan.
