TSTool Documentation <br />Introduction - 2 <br />The GeoView Mapping Tools appendix provides a general reference for the GeoView map interface. <br />The mapping interface is being phased in. <br /> <br />This documentation can be printed double -sided and is best viewed as PDF to use the navigable table of <br />contents and bookmarks. <br /> <br />2.1 TSTool Data Flow Concepts <br /> <br />Although TSTool can be used simply to browse and view data, the main function of TSTool is to <br />automate data processing using a workflow of commands. F igure 1 illustrates overall data flow concepts. <br /> <br /> Figure 1 – TSTool Data Flow Concepts <br /> <br />Input data are retrieved using unique identifiers, such as time series identifiers discussed in the next <br />section. The TSTool graphical user interface (GUI) is used to browse data, edit commands, run <br />commands (by calling the command processor), and view results. The command processor internally <br />manages data including lists of time series, time series ensembles, tables, and processor properties , and <br />provides access to the data in interactions with the GUI. The command processor also can output results <br />to files, databases, web services, and can create data products. Once configured, processing can be <br />automated. <br /> <br />The interpretation of input data and definition of workflow and data products depends heavily on <br />standards and conventions, some of which are defined by data providers, and some of which are defined <br />by the TSTool design. Although standards define specific features, TSTool allows users a great deal of <br />flexibility in defining workflows and producing data products. <br /> <br />14
