ABSTRACT

This chapter discusses the tablets are gaining acceptance as a reliable, comprehensive tool that can map crash and crime scenes, but that must be tied to GNSS. Bush used the robotic total station, yet was discovering that the extensive time, effort being absorbed with these combined systems was placing a huge workload on the DOT to capture control points at a scene they had previously documented as part of their mapping of all Oregon highways. Two years before these efforts by Trooper Bush, the Oregon DOT had been working on a project to provide some of its surveying supervisors with tablets, of which the first iteration was DT Research's DT391GS tablet that incorporated a GNSS board. The tablet’s key strength is that because it has the ability to establish and retain GNSS controls, data gathered from any other technology and merged with the tablet’s own captured data can be processed with the software.
