Abstract

|
|
The purpose of this study is to construct e-Nonsan, a user frienclJy river quality management information system for Nonsan-si basin using GIS (geographical information system) technology. GIS was ideally suited featuring a geographical characteristics{e.g., industries, cattle sheds) and very effectively used in mapping and symbolization for the distribution of the spatiaVperiodic status{e.g., pie or column chart) of the point/non-point pollutant source loads which can be effectively applied to a information system on the web-site. And a user interface, GUI{graphic user interface) was designed very diversely and simply enabled the and non-environmental experts connect with the system and obtain a useful information of river quality. e-Nonsan, a visual mapping system for river quality was developed by refrarning the monitoring data as grdphic symbols and it was ideally suited to exploring area-wide river quality at a user-frienclJy manner due to extensibility and scalability along the various survey points. Eventually the final step of this study was to construct e-Nonsan based on Web-GIS could be assessed anywhere if internet service is available and offer a very useful information services of the river quality to the publics.
