| Research Abstract |
Conducting 3D terrain mapping through airborne laser remote sensing technology, we extracted 50 cm mesh digital elevation models of ancient fortress sites in five locations and generated a highly accurate image of the variations in the terrain. In addition, we tested a survey method utilizing a simple, portable GPS(global positioning system) device to obtain location information of the fortress boundaries by means of GPS technology. Using this combination of techniques, we were able to establish a simpler and more precise approach to surveying than the previously used plane table surveying method. In this way, we were able to establish new groundwork for research based on data analysis utilizing various forms of GIS(geographic information systems) and for the management of survey data.
