<br />Figure 4-4. Riverside Flood DSS Prototype Using an Alternative Technology of ArcGIS Server and
<br />OpenLayers Web Browser Client
<br />Riverside recognizes that the default option is to extend the ArcIMS prototype, in which case the
<br />look and feel of the prototype system will be retained. However, there are limitations to this
<br />approach that should be recognized and discussed with the State.
<br />Approach
<br />Riverside will discuss with the CWCB at the project kickoff meeting an approach for evaluating
<br />alternative technologies. Relevant discussion topics may include:
<br />• The trade-off between continuing to use ArcIMS, risking future data and technology
<br />integration issues, versus using newer technologies and investing in development costs.
<br />• The option to use external data services that rely on other agencies to store, manage, and
<br />maintain data versus requiring all data to be housed at the CWCB.
<br />• The option to use a single web application versus multiple interfaces. For example, some
<br />technologies may be more appropriate for embedding maps in other pages. Multiple sites
<br />may be needed to implement private and public access to the system. A single server
<br />solution (e.g., ArcGIS Server) can supply data to multiple browser application solutions.
<br />• The approach to implementing services for key data components, which could be used by
<br />various applications, including the CDSS Map Viewer and the Flood DSS web application.
