the interface will have links to the INFORMIX database, it is unlikely that a PC version of the <br />interface could be developed without a large expenditure. <br />Consumptive Use Model <br />The consumptive use model interface will depend on the GRASS GIS for computations and the <br />ARC/INFO GIS for database administration. The consumptive use model interface will be a DMI <br />utility that retrieves spatial data and then prepares the data for the stand-alone consumptive use <br />models. The hardware requirements of the GIS products, and the dependence of the model interface <br />on the INFORMIX database, make it unlikely that the interface will be ported to a PC in the near <br />future. Much of the code used in the consumptive use model interface will be based on existing <br />coded developed at CSU. Consequently, the most cost-effective way to develop the CU model <br />interface is to rely on existing Motif and GRASS code. <br />The GUI developed for the CU model will be coded by IDS personnel familiar with existing code. <br />Consistent look and feel will be promoted by relying on Motif standards. Maintainable code will be <br />promoted through development of modular code (see GUI Task Memoranda 1.05-16 to 1.05-18) and <br />through thorough documentation. Year 1 efforts for the GUI-based CU DMI will address the issues <br />of the CU model (e.g., selecting the appropriate coverages needed to compute consumptive use input <br />data such as irrigated acreage). <br />CRDSS Interface <br />As discussed above, the main CRDSS interface will consist of a UNIX shell script that controls the <br />execution of the CRDSS applications. A graphical interface is desirable to control the execution of <br />some applications because results are graphical in nature (e.g., map-based displays). A GUI-based <br />CRDSS interface will therefore be coded using the XVT GUI builder and will consist of a menu- <br />based program that allows the major components of the CRDSS to be called. The CRDSS GUI <br />interface at the end of Year 1 will interact with the main components of the CRDSS, including the <br />AOP, CRSM, CU, and MODSIM models. Year 2 activities related to scenario handling will require <br />that more DMI utilities are called by the GUI. <br />Applications that do not typically need to be executed in a graphical environment (such as <br />administrative tasks) will be excluded from the GUI. <br />The CRDSS shell interface and GUI will be developed at RTi. The applications developed in other <br />tasks will be coordinated through task 1.05 so that the main CRDSS interface can effectively run all <br />CRDSS applications. <br />Database Browse Tools <br />Tools will be identified during Year 1 and will allow developers and users to browse the database. <br />RTi will be developing tools for database administration using INFORMIX products such as <br />INFORMIX 4GL to browse the database contents. These tools will generally be written to display a <br />single table in the database and will primarily be used for database management (e.g., QA/QC of <br />data). The form-based 4GL scripts will be made available to the State so that State personnel can <br />browse the database. This type of database browse tool is not GUI-based. <br />5 <br />A275 07.28.94 1.05-31 Malers <br />
