VEHICLE-BASED MOBILE MAPPING SYSTEM FOR THE FREQUENT UNSCHEDULED REVISION OF NATIONAL BASE MAP

摘要

This study is on the adapting vehicle-based mobile mapping system to the frequent unscheduled revision of 1:5000 scale national base map. We analyzed map layers which could be built by vehicle-based mobile mapping systems and studied surveying methods for each layers. Also, the methods of maintain surveying accuracy to satisfy accuracy standards of national base map were suggested. The maps of Yoido, Hyangnam, and Suwon area were revised by vehicle-based mobile mapping system on a trial bases and possibility of utilizing vehicle-based mobile mapping system for map revision was analyzed. Also accuracy estimation of vehicle-based mobile mapping system was conducted. For this, we built a Test-bed to calibrate sensors and surveyed check points (181 points) in study areas. As a result it was revealed that vehicle-based mobile mapping systems were adequate for irregular revision of national base map.
