Wooden rack built by Keith Sprengel holding power boards and laptop computers components of the first Digital Aerial Sketch Mapping (DASM) system used in Region 6 functionally. Two systems allow two aerial observers digitize data simultaneously - each looking out one side of the airplane. The KDS touchscreen components are sitting on the table.

Note: The transition from collecting data on paper maps to digital data collection with DASM happened over the course of several years of testing. The first year for 100% DASM data collection in Oregon and Washington was 2003.
