^ enhancements related to updated HydroBase irrigated acreage tables <br />^ integrating the StateDMI map interface with StateCU data (e.g., to select parcels <br />associated with a diversion or well) <br />^ other miscellaneous clean up. <br />Deliverables: <br />140.1 An updated StateDMI application, with updated documentation, with enhancements <br />necessary to support the current version of StateCU to be used in the SPDSS. <br />Task 149 -More Graphics in Web Displays <br />Objective: <br />Implement amap-based ArcIMS server on the CDSS web site, to provide access to spatial data <br />and serve as an interface to HydroBase data. <br />Background: <br />The CDSS web site is a primary data source for users who have not purchased HydroBase and <br />software on CDs. Data available on the CDSS web site primarily consist of text-based reports <br />and delimited data. The organization of data views is consistent with StateView/CWRAT. <br />Detailed data for stations or structures requires selecting from a list of available <br />stations/structures. Real-time data are available in tabular and graphical form via a link to the <br />DWR web site. <br />Recent CDSS enhancements have resulted in an increased emphasis on the use of GIS and <br />spatial data in applications with graphical user interfaces. Spatial data products have also been <br />made consistent by water division, with ArcView and ArcExplorer projects and associated <br />shapefiles being available at no cost. The spatial data for CDSS have been developed somewhat <br />independently of other spatial data maintained by the State (DWR and CWCB). Discussions <br />with DWR GIS staff indicate that efforts have been ongoing to implement an ArcIMS server for <br />spatial data. However, although such efforts can be compatible with CDSS efforts, DWR staff <br />efforts will likely focus on internal needs and data (e.g., well permit locations). DWR expects to <br />use an existing ArcIMS license and server for a public web site, but it is unclear whether <br />sufficient resources truly exist for SPDSS/CDSS efforts. The focus of development will be to <br />implement working tools consistent with previous efforts allowing each party to focus on <br />deliverables for their respective projects. Development will be coordinated through initial design <br />meetings and continued communications in order to produce consistent data products and tools. <br />Spatial data products will be shared where possible to avoid duplication of effort and multiple <br />versions of data. Later efforts can build on the initial system. <br />The activities performed in this task will facilitate the implementation of ArcIMS or other <br />dynamic map based viewers under a separated scope if determined appropriate by the State. <br />Approach: <br />
