| Scenario |
| Disease Control System interface |
|
|
| The Centers for Disease Control (CDC), R.O.C, is responsible for national disease prevention, quarantine and surveillance. CDC has complete information on reported contagious disease cases. In order to process and analyze the disease data, CDC needs to develop a better system to fully monitor and control the diseases and provide necessary information to all levels of medical organizations and the public. Since disease cases and infection sources are highly related to geographic distribution, many Disease Control Agencies from both domestic and international use GIS to describe variance data to assist research analysis. CDC started to develop disease control GIS in 2001 to assist each unit to improve the result of disease control. |
| |
| Challenges |
| The Disease Control Geographic Inforamtion System is to control and monitor diseases in order to make the system more effective and complete for users to get hold of information more easily. The system also includes Condition Reporting System and Phthisis Reporting System for more agencies to record different information through GIS for research analysis and control. |
| |
| Goals |
| The goal of the system is to present disease information through electronic maps for display and manipulation. The system also includes the analysis of clustering diseases, which displays the regions and degrees of clustered infections for the work of disease prevention. A web-based Internet search platform is also included, combining vector maps and satellite images to display more accurate map information. In addition, the web-based platform is fast and easy to access, providing real-time disease geographic information. |
| |
| Solutions |
| The map server software that the CDC used was slow in displaying data and will often result in failure of access or even total system failure when many users are logged onto the server at the same time. Therefore, this project replaced the core map server software to SuperWebGIS to increase the speed of map display, which not only solved the system failure problem when many users are logged-in simultaneously but also provided a much more stable system in whole. |

| Results |
 |
The query interface of the Disease Control Geographic Information System |
|
| Although this project costs more effort and time to change the core system, the new system provides users an environment that is faster in speed, more pleasing in terms of the interface, more user-friendly and more effective in the control and surveillance of diseases. |
