This project aims to develop an Web-based GIS for the Center for Disease Control and Prevention (CDC) to manage and visualize malaria risk information worldwide. The system is targeted for use by both general public (travelers) and medical professionals. Usability, scalability and performance are the primary concerns with the existing CDC malaria mapping application. Our plan is to redesign the application to achieve a high performance system with an interactive interface while providing a better user experience. One challenge lies in the fact that a huge volume of data (approximately 7 million data-points with some 5 million of populated risk factor variables) must be handled. Presenting the information needs to be done intelligently.

• ArcGIS Server has been set up.
• [10/12/2007] Anand and Shaowen have acquired the necessary ESRI Arc V9.2 software.
• [10/9/2007] Ian and Wendy are working on readying accounts for Anand, Eric, Shaowen, and Yan to access two NCSA systems (one for development and the other for deployment).
• [Nov 2007] Installed ArcGIS Server S/W and created test application
• [Dec 2007] Waiting for the Data from CDC
• [Dec 2007] Reviewed the Web Services code from CDC team. The ArcGIS portion of the code is still in development version.
• [Dec 2007] Additional requirements necessitate that we have to code in .NET version and use VB .NET
• [Jan 2008] We have created the necessary maps using ArcMap.
• [Jan 2008] Map Service has been deployed on the ArcGIS Server.
• [Jan 2008] An initial development version of application has been developed.
• [Jan 2008] Development Version 1 - http://purdy.ncsa.uiuc.edu/devtest1
• [Feb 2008] Adding new features, like AJAX search.
• [Feb 2008] New feature. Zoom into city of country based on search.
• [Feb 2008] Implement the “I am feeling lucky” king of search and the corresponding zoom in.
• [Feb 2008] Conducted an application usability testing and implement improvements based on the suggestions.
• [Feb 2008] Wrote the user guide
• [Mar 2008] Created a tool which will automatically update the map when the DB gets update.
• [Mar 2008] Installed VMWare and the ArcGIS server on the VMWare instance
• [Mar 2008] Production server is ready, but we are waiting on updated data from CDC.

• ESRI Arc tools: V9.2 (ArcIMS, ArcSDE, ArcGIS). Development is planned in Java.
