Construction of Geothermal Information Database for Korea Based on Web GIS

Abstract

In order to build an information infrastructure for the development and application of geothermal energy, KIGAM (Korea Institute of Geoscience and Mineral Resources) is setting up a Web GIS-based database for geothermal resources in Korea. The database of geothermal information includes numerous measurement data from rock samples and boreholes such as thermal properties (rock density, specific heat, thermal diffusivity, thermal conductivity, etc), geothermal gradients, heat production and heat flow. The distribution maps showing thermal conductivity, geothermal gradient, heat flow, and heat production constructed with measurement data are also included to the database. An application system for the database was developed using ArcGIS Server engine software. Users can easily find the geothermal data for the area of interest using the functions on the system’s menu such as ‘query’ and ‘analysis’.
