APPLICATION OF GEOINFORMATICS FOR DIGITAL DATA UTILIZATION IN THE FIELD OF ARCHAEOLOGY

摘要

Low cost laser scanning and photogrammetry has turned out to be an effective method not only for its rich information (i.e. ortho photo, 3D data, recording microtopography) but also reducing time and man power in archaeological record taking. However, there were still several difficulties under severe condition, such as strong sun light casting shadows which effects the photogrammetric processing, and vegetation covering the surface which increases the error in laser scanning. Data mining techniques from excavation reports were also helpful to manage and gather archaeological records from surveyors point of view. Integration of both methods of spatial data measurement and data mining / analysis can play a significant role to suppo rt the interoperable use and deployment of archaeological information(fig.4). It can also be supportive to understand the present status of region as a result of continuous interaction in the area when these archaeological / historical information are uplo aded in an inter- operable manner.
