Abstract:
This report documents the findings of a technology transfer project to demonstrate the effectiveness of a portable field mapping system to landslide field reconnaissance work. The objective of this project was to expose the latest field data collection and real-time mapping technologies to the geotechnical staff within the California Department of Transportation (Caltrans) through the use of two field mapping units on existing projects. Two field mapping units were integrated by the consultant and made available for use to Caltrans staff to assist in the rapid development of topographic maps, cross-sections, and descriptions of landslides for engineering analyses and reports. Various types of positioning instrumentation were incorporated into the field mapping units to evaluate field performance and accuracies, debug the system, and develop customized packages for specialized applications for Caltrans end-users.
Obtaining sensor orientation by direct measurements is a rapidly emerging mapping technology. Modern GPS and INS systems allow for the direct determin...
