A multi-disciplinary approach to WNV surveillance required the Chicago Department of Public Health to develop a WNV data repository. WNV Surveillance requires several CDPH units share data outside of traditional roles and coordinate efforts with other City of Chicago departments to collect and process data. The integrated data repository allowed for standardized geographic reporting and analysis, which had previously been performed manually and replicated in each office. To detect communicable diseases, involves an Oracle database with Access front-end, a Java API for batch geocoding, and Visual Basic to dynamically generate maps.
This paper published by Environmental Systems Research Institute states that ArcIMS is a multitiered software product for distributing interactive maps using standard Web protocols. A connector is required so that a Web server can access the ArcIMS Application Server and Spatial Server to create maps dynamically. ArcIMS provides various connector options: servlet; Java; ColdFusion; ActiveX; and, with the release of ArcIMS 9 - .NET Link. This paper discusses the use of the .NET Link to create custom ArcIMS clients. ArcIMS 9 requires both .NET Framework 1.1 and .NET Framework 1.1 SDK to install the .NET Link and Developer Help feature.
