funded agencies should ideally make their data available in a standard format, for inclusion in the Flood <br />DSS. Or, at a minimum, some level of data consistency should occur, to allow the Flood DSS to direct <br />users to a county or municipal web site. For counties and municipalities without sufficient resources, the <br />Flood DSS standards should be defined and applied consistently, to provide users with consistent data <br />across political boundaries. Regardless of approach, effort to define standards and procedures should <br />occur with the Flood DSS effort. The initial effort may be to coordinate standards development, perhaps <br />initially as part of data inventory efforts, with follow -up via appropriate meetings or correspondence with <br />agencies such as the CASFM and the State GIS Coordinator. An attainable goal may be to use the Flood <br />DSS effort to standardize metadata and data processes, which will then allow for more rigorous inter- <br />agency standards to be developed in future years. <br />3.3 Software /System Recommendations for Full -Scale Flood DSS <br />The following recommendations are related to the full Flood DSS software /system, involving additional <br />software development and /or system integration. Additional evaluation performed below should consider <br />the results of the User Needs Assessment described in Section 3.1. <br />3.3.1 Evaluate Alternative Technologies for Flood DSS <br />The Flood DSS prototype utilizes ESRI's ArcIMS software, which is mature but also has known <br />limitations. ESRI also phases out older products over time as new products are released. An evaluation <br />of user needs, CWCB IT plans, and ESRI support may identify cases where existing ArcIMS technology <br />cannot meet requirements. Consequently, an evaluation of alternative technologies may be appropriate, <br />before a full -scale Flood DSS is implemented. <br />ESRI's next generation of map server software is the Server product. ArcServer allows additional <br />customization of features and allows software modules to be reused among various ESRI products. For <br />example, a tool to process SNODAS data could be utilized similarly in desktop GIS and in the ArcServer <br />web application. Based on recent information from ESRI, it is likely that ESRI will be encouraging <br />existing ArcIMS users to convert to ArcServer in the near future. <br />3.3.2 Content Manager Replacement <br />The CWCB currently uses IBM's Content Manager software to manage and view scanned documents. <br />However, Content Manager is being replaced by a new product, which has different functionality. <br />Consequently, the features implemented for the prototype Flood DSS will need to be upgraded to <br />integrate with the new document system. It is recommended that the requirements of the Flood DSS be <br />considered when implementing the new system. The effort to utilize the new system cannot be fully <br />estimated at this time until more is known about the CWCB's implementation of this new system. <br />3.3.3 Automate Flood Outlook, SNODAS, and SNOTEL Data Processing and <br />Management <br />The prototype Flood DSS includes snapshots of the HDR flood outlook products, SNODAS gridded data <br />(Snow Water Equivalent), and SNOTEL site data. Providing a statewide clearinghouse for these data to <br />be provided in a timely fashion will require enhancement to automatically download, process, and <br />manage data from the original sources, and provide as layers in the Flood DSS Map Viewer. An <br />evaluation of user needs should occur to determine the number of days of products to display, and the <br />data types and statistics utilized in displays (e.g., whether a layer for "change in SWE" is made available). <br />Some level of quality control is likely also needed to verify the reliability of data products. However, <br />since the original providers of the data are presumably performing review and validation before <br />publishing the data, a totally automated solution may be appropriate. The procedures to process the data <br />should be documented to allow for additional enhancements and maintenance of the system. <br />11 <br />
