Database Architecture for Secondary Use of Geoinformation

Abstract

The database architected by the authors has been used to establish the geological model and to analyze the mechanical behaviors of ground from the geotechnical engineering viewpoint. It is the distinguished feature for the proposed database that the “observation articles” in the boring log are taken account of, which makes the prompt search of geoinformation to identify the sedimentary environment of strata easy. Furthermore, the authors have architected a prototype to manage the ground meshes of geoinformation, which means to be the secondary use of geoinformation registered in the database in this paper. By using the secondary geoinformation, it may be considered to be easy to collect the geoinformation possessed by the private organizations. As a result, it is considered that the proposed database contributes to improve the accuracy of 3D model of ground.
