develop a graphical network builder that allows a model network to be constructed from data <br />located in HydroBase. <br />Background: <br />The existing Makenet application uses a network file created in an editor to create a PostScript <br />network diagram and preliminary station files for StateMod. Makenet execution is controlled by <br />"commands files". The editing of the model network and the commands can be performed more <br />efficiently using a graphical user interface. <br />The StateDMI program has previously been implemented to build files for the StateCU model, <br />using individual command editor dialogs for each command. It is expected that all network <br />display tools will share some level of common features with specific features being available for <br />each application, as appropriate. Therefore it is appropriate to include Makenet within StateDMI. <br />However because the resulting StateDMI may be too complex for many users the Makenet DMI <br />developed herein will operate both stand-alone or as part of StateDMI. <br />Makenet enhancements potentially required to handle water administration issues that are unique <br />to the South Platte as described in the background section of Task 18 are expected to be <br />performed under a separate scope of work in a subsequent phase. <br />Approach: <br />137.1 Include Makenet Features in StateDMI. The existing Makenet processes <br />approximately 34 commands, to produce a model network PostScript file and three <br />preliminary StateMod files (.rin, .ris, .rib). Menus will be added to the StateMod menu in <br />StateDMI for each of these StateMod files and command editor dialogs will be created for <br />each of the Makenet commands, utilizing existing commands where already in place in <br />StateDMI (e.g., for control commands like setting the debug level). Because the resulting <br />StateDMI may be too complex for many users the Makenet DMI developed herein will <br />operate both stand alone or as part of StatDMI. Interaction with HydroBase will occur using <br />stored procedures and will utilize technology upgrades described in Task 155. <br />137.2 Develop a Graphical Network Builder A graphical network builder will be <br />developed that allows a model network to be constructed from data located in HydroBase. <br />The network builder will use drag and drop technology that allows features like a diversion, <br />reservoir, stream gage, instream flow, well and carrier to dragged from the screen and placed <br />onto the network. It will interact with HydroBase to obtain "official" station ID's and names. <br />This interface will replace the current practice of editing a network file manually, although <br />that capability will be maintained. The network editor will allow output to a file and directly <br />to a plotter, eliminating the need to use intermediate PostScript files for viewing the network. <br />The specific data file format for the updated data network will be determined during this task <br />but is envisioned to consist of spatial data with attributes (e.g., shapefiles) consistent with <br />GIS applications. An example of how the network editor might function is as follows: <br />
