CRDSS <br />TASK MEMORANDUM 1.05-17 <br />Study of System Integration Issues <br />GUI - Network Display <br />1.0 ISSUE <br />The main function of a network display tool is to represent a conceptual model for a physical system. <br />The network of nodes and arcs displayed on the screen can then be used to interface the data for the <br />network, e.g., physical characteristics, priorities. A network display tool is useful when creating and <br />editing networks for the water rights planning model, but may not be used by end-users. Such a tool <br />will also be useful in other modeling efforts in later years, such as the Big River model or the water <br />rights administration tool. <br />2.0 DISCUSSION/ANALYSIS <br />A general network display tool is one that can read a "network" consisting of nodes and links and <br />display the network in a useful fashion. It is anticipated that the physical aspects of networks will be <br />generalized so that they can be stored in the CRDSS database (either in INFORMIX or as flat files). <br />Future task memoranda from the water rights modeling task will address this issue. The network <br />tool will read such a network from the database and allow the network to be displayed and edited. <br />Figure 1 illustrates the basic components of such a tool. The tool will have display control options <br />(upper right corner in figure) and editing features that would allow the network to be easily modified. <br />If GIS overlays are desirable in this tool, then the features of the network editor may be added to the <br />display tool (see Task Memorandum 1.05-16). In any case, routines developed for the general <br />display tool may be useful for the network tool. <br />Options <br />Demand1 Physical <br />Demand2 Schematic <br />Convergence1 <br />Palette <br />Res3 <br />Res1 Reservoir <br />Diversion <br />Loss <br />Res2 Import <br />Arc <br />2 <br />Figure 1.
