在过去的几十年中，更省时的机载地球物理数据采集系统的发展使得大比例尺制图在规划和管理中具有吸引力和可负担性
例如，地下水资源或原材料矿床。要处理和优化使用覆盖广大地理区域的大型地球物理数据集，就需要有一个系统，能够方便地存储、提取、解释、合并数据，并为不同目的一次又一次地使用数据。
丹麦在过去十年中开发了这种在全国范围内管理和利用水文地球物理数据的综合系统。
该数据处理系统包括一个综合的国家地球物理数据库（GERDA数据库）、一个国家钻孔信息数据库（Jupiter数据库）、一个程序
该软件包用于处理、解释和可视化电气和电磁数据，以及准备这些数据上传到地球物理数据库（奥胡斯地球物理数据库），最后是用于地质建模和数据质量控制的3D可视化和建模工具。Aarhus地球物理数据库程序包允许对来自地球物理数据库的数据子集进行可视化和分析，其中可能包括来自许多个人的数据。
测绘运动。3D可视化和建模工具直接使用地球物理和钻孔数据库中的数据;此外，它还处理奥胡斯盆地中生成的地图和网格。
水文地球物理数据综合管理系统可以管理几年来在不同的测绘活动中、不同的咨询公司以及用不同的地球物理方法和仪器收集的大量数据。现在所有合作伙伴都在使用
参与了丹麦的地下水测绘。该系统促进了地球物理数据和模型在未来测绘项目中的重复使用，并简化和促进了地球物理数据在地质建模中的使用。该综合系统确保从数据采集到地球物理数据的处理和反演到地质建模的所有文件的传输
通过存储数据采集参数、数据处理参数、反演参数
以及地球物理数据库中的数据和模型的不确定性。
在国家地球物理数据库中收集的大量地球物理数据的好处和两个程序包的使用是非常宝贵的所有未来的地下水规划和管理。
Development of more time-efficient and airborne geophysical data acquisition systems during the past decades have made large-scale mapping attractive and affordable in the planning and administration
of e.g., groundwater resources or raw material deposits. The handling and optimized use of large geophysical data sets covering large geographic areas requires a system that allows data to be easily stored, extracted, interpreted, combined and used one time after another with different purposes.
Such an integrated system for management and utilization of hydrogeophysical data on a national scale has been developed during the past decade in Denmark.
This data handling system includes a comprehensive national geophysical data base (the GERDA data base), a national data base for borehole information (the Jupiter data base), a program
package for processing, interpretation and visualization of electrical and electromagnetic data as well as preparation of these data for upload to the geophysical data base (the Aarhus Workbench) and finally a 3D visualization and modelling tool used for geological modelling and data quality control. The Aarhus Workbench program package allows visualization and analysis of subsets of data from the geophysical data base, which may include data from many individual
mapping campaigns. The 3D visualization and modelling tool uses data from the geophysical and the borehole data bases directly; moreover, it handles maps and grids produced in the Aarhus Workbench.
The integrated system for management of hydrogeophysical data allows management of large amounts of data collected over several years in different mapping campaigns, of different consultant companies and with different geophysical methods and instrumentation. It is now used by all partners
involved in the groundwater mapping in Denmark. The system promotes reuse of geophysical data and models in future mapping projects, as well as easing and promoting the use of geophysical data in the geological modelling. The integrated system secures transfer of documentation all the way from data acquisition over processing and inversion of the geophysical data to geological modelling
through storage of data acquisition parameters, data processing parameters, inversion parameters
and uncertainties on data and models in the geophysical data base.
The benefits of the large amount of geophysical data gathered in the national geophysical data base and utilized by the two program packages are invaluable for all future groundwater planning and administration.
