Shows all of the recorded crashes in the Yosemite area. Crashes were mapped using Latitude/Longitude coordinates where available and a link node, node direction and node distance method otherwise. Those that could not be mapped in either fashion were included as stand alone tables. CDS records are related via relationship classes to records in the Passenger table and Units table and IMARS data is related to Passenger and Vehicle tables. In both cases relationship classes are one to many relationships.
