In order to elevate and provide the national drinking water plan and management for reference; therefore, the geographic information system of the drinking water source protection area was predicted to realize the following purposes. First of all, in order to help Taiwan Environmental Protection Bureaus (EPB) to confirm and understand land managed in drinking water source protection area. As a result, web geographic information system, such as ESRI Arc-IMS and Google Map, were used to integrate buffer analysis and indicator light, and then the project team established the geographic information system of the drinking water source protection area. Secondly, in order to improve Taiwan environmental protection bureaus to process the operations of onsite survey. For this reason, the mobile reporting system of national drinking water source protection area was established to combine with PDA and alerting technique. Thirdly, 4 types and 26 data of geographic information system were collected and updated for Taiwan environmental protection administration. Finally, the project team interviewed with six environmental protection bureaus, which include Taipei County, Yilan County, Miaoli County, Chiayi County, Kaohsiung County, Pingtung County, and collected their requirements for system development.
