Prototype of Web-based Geological Data Sharing System using Free and Open Source Software
Abstract
Two-dimensional (2D) geological data, such as geological maps and geological cross-sections, have been shared to the public on the Web, due to its importance in understanding subsurface geological conditions. However, ordinary people cannot figure out subsurface geological conditions only from these 2D data. The purpose of this study is to share various types of geological data to the public in easy-to-understand style on the Web. For this purpose, we developed a prototype of web-based geological data sharing system using free and open source software. As a result, the developed system allows the users (1) to map locations of borehole logs with a geological map, (2) to search database for borehole logs by keywords, (3) to browse a surface-based geological model within arbitrary range, and (4) to generate a geological cross-section along arbitrary lines. The geological map and surface-based geological model have been constructed based on borehole logs beforehand. The geological cross-section can be generated from the surface-based geological model on-demand. In this system, all functions can be performed through a Web browser. In addition, a distribution of borehole logs and the surface-based geological model can be visualized in three-dimension (3D). The 3D visualization of geological data on the Web assists users in understanding subsurface geological conditions quickly and correctly with or without previous knowledge of geology. In conclusion, the developed system contributes to create better environments for promoting utilization of geological data. This work was supported by JSPS KAKENHI Grant Number JP16K21677.
