2.4 Data Processing <br />Data processing occurred after data collection for some layers in order to create data suitable for the <br />prototype. <br />2.4.1 Data Quality Assessment and Utility of Data for Web - Serving <br />All data received for input into the DSS underwent an initial evaluation for data quality assessment and <br />utility for web serving. This task primarily involved organizing the data in an ArcGIS project (mxd) and <br />visualizing the information with various base layers. Once the line work and attributes were validated, <br />the data were subjected to various pre - processing activities in order to prepare the information for serving <br />in the DSS. <br />2.4.2 Data Pre - Processing <br />This task primarily involved converting data to a format usable by a map service, projecting data to the <br />project coordinate system, symbolizing data, and organizing data into appropriate data groups. Details of <br />this process for each data layer are contained in Table A.1. <br />2.5 Adapt Existing CDSS Map Viewer for Main Interface <br />Existing CDSS Map Viewer files were utilized to create a website for disseminating the flood <br />information. The look and feel and features of the existing site were maintained, and the map layers <br />configured using a similar grouping system used in CDSS Map Viewer. Data layer symbols are <br />consistent with the CDSS Map Viewer, and utilize standard symbols where possible. Feedback from the <br />State on data layer grouping and symbols facilitated this process. <br />2.6 Implement Access to Non - Spatial Data <br />Non - spatial data refer to available, useful information that needed to be linked to the DSS, specifically <br />Content Manager documents. In this task, the existing Content Manager system was evaluated to <br />determine how to utilize scanned documents. <br />2.7 Implement Map Links to Non - Spatial Data <br />Non - spatial data refers to available, useful information that needed to be linked to the DSS, specifically <br />Content Manager documents. <br />2.7.1 Content Manager <br />Links to Content Manager have been made available using a variety of combinations of user input. In the <br />Flood DSS Prototype the primary access route is via hotlink information that has been embedded in <br />spatial data attributes. This allows the user to access "all documents" or "documents by type" in Content <br />Manager. This is achieved by making either the `Counties', `Cities', or `Rivers' layers active in the Base <br />data group, and selecting a County, City, or River using the document hotlinks on the DSS toolbar <br />(Figure 1). <br />
