DSS Component Assessment <br />4.1.7.1 Implementation <br />Implementation of a GIS for the Rio Grande basin could be completed readily from existing tools. <br />However, there is not a comprehensive coverage for the entire basin. Baseline information has been <br />compiled for much of the basin. Component-specific coverages have not been compiled except in <br />localized areas. <br />4.1.7.2 Spatial Scope <br />Spatial coverages and resolutions vary for the different data types. All data will be converted to <br />ARC/INFO format and projected to a common projection to be used in ARCVIEW or ARC/INFO <br />applications. The time allotted for the development of these spatial data layers does not include field <br />reconnaissance or other ground truthing. The raw data supplied by other parties may contain errors. <br />After conversion of the raw data to ARC/INFO format, these errors will still exist. Data from different <br />sources may not overlay correctly and may have to be corrected. In general, data from the same <br />source with the same scale should overlay correctly. <br />4.1.7.3 System Requirements <br />The RGDSS GIS coverages could be developed on a UNIX workstation using ARC/INFO and <br />methods similar to those used in CRDSS. GIS analysis and viewing capability on a PC are available <br />for ARC/INFO using ARCVIEW. GIS analysis and display efforts are typically large, data-intensive <br />activities. Typical system configurations require large amounts of computer disk space and enhanced <br />display capabilities. <br />4.1.7.4 Data Requirements <br />Data types suggested for inclusion in the RGDSS spatial database are summarized in Table 3-4. <br />4.1.7.5 Specific RGDSS Issues <br />Most of the data contained in the coverages listed above are in the public domain and are available at <br />minimal cost. Some coverages will require development for tabular data, such as locations for stream <br />gages and climate station. <br />4.1.8 DSS Integration -Documentation <br />System hardware, software, design, and implementation documentation in the form of users' and <br />developers' manuals should be included with the RGDSS. Water resources planning model manuals <br />should also be included for each basin. All documentation should be available over the Internet using <br />hypertext markup language (HTML) standards. Documentation was identified in CRDSS as critical to <br />the overall success of the project and the same will be true for the RGDSS. Objectives of the end-to- <br />end documentation process are to provide mechanisms for feedback early in the development process, <br />to facilitate communication between all users and developers of the RGDSS, to provide the support <br />infrastructure for maintenance and future development of the system, and to provide training <br />materials. <br />4.1.8.1 Implementation <br />The following manuals are suggested: <br />• RGDSS Overview <br />• Users' Manual <br />• Model Documentation (generic) <br />• Model Applications (basin specific) <br />a454/report/final/comp. doc 07/2&~OS Y- <br />
