研究了地热数据库数字数据模型的概念模型和物理实现。系统的要求是，该系统应该能够管理各种类型的地热数据集与他们的复杂行为相对于我们的地球的三维性质。它利用了最先进的地理信息技术趋势，并符合其他地球科学领域的数据库项目。这一探索提出了一个集成开放平台地理信息系统（GIS）和关系数据库管理系统（RDBMS）的核心系统。GIS和RDBMS的集成允许复杂和空间化的数据库，其中数据库的相互交织的内容可以可视化地查询。然而，这个系统是开放的，与其他系统高度可互操作；这是实现地学领域间信息共享的关键，也是实现综合地质分析系统（即将数据标注、管理、分析建模和可视化过程集成到单一工作流程中）的关键。我们使用环境系统研究所（ESRI）的ArcGIS软件包及其地理数据库数据模型进行数据模型的物理实现。地热事件建模为概念、发生和描述。采用ESRI地质数据模型和北美数字地质图数据模型作为起点。案例研究是在印度尼西亚的爪哇岛进行的。本文处理了不同数据类型的不同项目情况，包括来自地热勘探区的调查数据集、来自生产地热田的井眼数据集和一个岛屿规模的地热汇编项目。该模型已被证明是可行的，许多智能GIS工具都适用于地热应用。拓扑规则用于对数据内容设置约束，关系类用于创建表间网络，线性参考系统用于对井眼数据建模。使用地图接口成功地查询数据库内容，并从中进行进一步分析和生成可视化。最后提出了一个初步的地热数字数据模型，并提出了今后的发展方向。
The conceptual model and physical implementation of a digital data model for geothermal databases are investigated. The system requirements are that the system should be capable to manage various types of geothermal datasets with their complex behaviors in respect to the 3D nature of our earth. It utilizes the state-of-the-art geoinformation technology trends and conforms to database projects among other geoscience fields. This quest comes out with a core system that integrates an open platform geographic information system (GIS) and a relational database management system (RDBMS). The integration of a GIS and RDBMS allows complex and spatially enabling databases, in which interwoven contents of a database can be interrogated visually. Yet this system is open and highly interoperable with other systems; these are keys for easiness of information sharing among geoscience fields and towards the realization of an integrated geologic analysis system (i.e., integration of data caption, management, analysis-modeling process and visualization into single workflow). We use the ArcGIS package and its geodatabase data model from the Environmental Systems Research Institute, Inc. (ESRI) for the physical implementation of data model. Geothermal events are modeled as Concept, Occurrence, and Description. The ESRI Geology Data Model and North American Data Model for digital geologic maps are adapted as the starting point. The case study is conducted in the Java island, Indonesia. Different project circumstances with different data types are dealt with, including survey datasets from a geothermal prospect, a borehole dataset from a producing geothermal field, and an island-scale geothermal compilation project. The model is proven workable and many intelligent GIS tools are applicable for geothermal applications. Topology rules are used for setting constraints on data contents, relationship classes for creating networks among tables, and the linear referencing system for modeling borehole data. Database contents are successfully interrogated using a map interface, from which we conduct further analysis and produce visualization. A preliminary digital data model for geothermal is finally proposed and some future developments are suggested.
