3D data- and model management for the geo-sciences with particular emphasis on topology and time

与拓扑学相关的三维数据和模型管理是地球科学中备受关注的问题。特别是拓扑结构可以用于地质或地球物理定义的表面和固体的建模和管理。因此，使用分层拓扑g -map的更大单元可以在不同的细节级别上定义。这是通过在所谓的轨道上的不同维度（0D - 1d - 2D - 3D）进行导航来完成的，这些轨道允许在节点、边缘、面和体积之间进行环形导航，甚至可以在单个模型中进行时间（4D）导航。在项目的继续阶段，目标是使用这种与维度拓扑无关的方法来管理地球科学3D模型中的空间对象的拓扑，包括它们的时间依赖性直接进入地理数据库，并将拓扑与几何和地质参数联系起来。作为地球科学的具体例子，考虑了osnabr<e:1> ck附近的Piesberg填埋场情景和储层模型。除了德国北部的二氧化碳封存——对二氧化碳在储层岩石中的长期传播预测进行定量评估并进行风险评估——与应用地球科学合作，使用了地热能场景，其中存在一个数字3D储层模型。地质数据库包括研究区内的热力学、地质和地球物理参数，这些参数对时间的依赖性很大。

The 3D data and model management related to topology is in various ways of deep concern in the geosciences. Particularly well topological structures can be used for the modeling and managing of geologically or geophysically defined surfaces and solids. Thus, larger units using hierarchical topological G-maps can be defined in different levels of detail. This is done by navigating through different dimensions (0D -1D - 2D - 3D) on so-called orbits that allow the annular navigation between nodes, edges, facets and volumes and even at the time (4D) in a single model. In the continuation phase of the project, the objective is to use this dimensional topology-independent approach to manage the topology of spatial objects from geoscientific 3D models including their temporal dependence directly into a geodatabase, and to link the topogoy with the geometry and geological parameters. As concrete examples of the geo-sciences, the scenarios Piesberg landfill near Osnabrück and the reservoir modeling are considered. Besides the CO2 sequestration in northern Germany - to carry out quantitative assessments of long-term propagation prediction of CO2 in the reservoir rock and perform risk assessment - in cooperation with the applied geo-sciences a scenario of geothermal energy is used, for which there exists a digital 3D reservoir model. The geo-database covers thermodynamic, geological and geophysical parameters in the study area which are highly dependent on time.
