The main research task addressed in this project is to construct a Data System for StructuralGeology and Tectonics (SG&T). SG&T data are complex for a variety of reasons, including thewide range of temporal and spatial scales (many orders of magnitude each), the complex three-dimensional geometry of some geological structures, inherent spatial nature of the data, and the difficulty of making temporal inferences from spatial observations. To successfully implement the step of developing a SG&T data system, the principal investigators must simultaneously solve three problems: 1) How to digitize SG&T data; 2) How to design a software system that is applicable; and 3) How to construct a very flexible user interface.To address the first problem, the principal investigators introduce the "Spot" concept, which allows tracking of hierarchical and spatial relations between structures at all scales, and will link map scale, mesoscale, and laboratory scale data. A Spot, in this sense, is analogous to the beam size of analytical equipment used for in situ analysis of rocks; it is the size over which a measurement or quantity is applicable. A Spot can be a single measurement, an aggregation of individual measurements, or even establish relationships between numerous other Spots. They will implement both a Spot and a more traditional Mapping mode for data input. To implement these approaches into a software system, they will utilize a Graph database - as opposed to a Relational database - to better preserve the myriad of potentially complex relationships. A Graph design is ideally suited for the complex relations inherent in a SG&T data system. Finally, they will construct a user interface that is intuitive, open source, and spans as many operating systems and devices as possible. For these reasons, they will develop a web-application that can run in both a connected (on the internet) and disconnected mode.

本课题的主要研究任务是建立一个构造地质与构造学数据系统（SGT）。由于各种原因，SG T数据是复杂的，包括时间和空间尺度范围广（每个尺度有许多数量级），某些地质结构的复杂三维几何形状，数据固有的空间性质，以及难以从空间观测中进行时间推断。为了成功地实施SGT&数据系统的开发，主要研究者必须同时解决三个问题：1）如何处理&SGT数据;为了解决第一个问题，主要研究人员引入了“Spot”概念，该概念允许在所有尺度上跟踪结构之间的层次和空间关系，并将地图尺度，中尺度和实验室尺度数据联系起来。在这个意义上，一个点类似于用于岩石原位分析的分析设备的光束尺寸;它是测量或数量适用的尺寸。一个Spot可以是一个单独的测量，一个单独测量的集合，甚至可以在许多其他Spot之间建立关系。他们将实现一个点和一个更传统的映射模式的数据输入。为了将这些方法实现到软件系统中，他们将利用图形数据库（而不是关系数据库）来更好地保留无数潜在的复杂关系。图形设计非常适合SG T数据系统中固有的复杂关系。最后，他们将构建一个直观、开源的用户界面，并尽可能多地跨越操作系统和设备。出于这些原因，他们将开发一个可以在连接（在互联网上）和断开连接模式下运行的Web应用程序。
