2001. First Digital Aerial Sketch Mapping (DASM) components: Laptops, power board, and KDS unit - with a back-up paper map in case of system failure. Wooden rack built by Keith Sprengel.
First Digital Aerial Sketch Mapping (DASM) system components: Laptops, power board, and KDS unit - with a back-up paper map in case of system failure. Wooden rack built by Keith Sprengel. Due to excessive aircraft vibration, foam was later added under laptops.
Excerpt from Forest Insect and Disease Highlights in Oregon, 2001, located here: www.fs.fed.us/foresthealth/docs/fhh/OR_FHH_2001.pdf
"In 2001, we implemented a digitally assisted sketchmapping system in much of western Oregon. Observers now record damage locations on a touch-sensitive computer screen displaying the airplane’s current position on user-defined electronic background maps. This system utilizes real-time global positioning and eliminates problems associated with observer disorientation."
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.
