Abstract

Many features of the Single Field version have been enhanced to provide user friendly interface. The County/Watershed version of NAPRA WWW system was further enhanced. The newly developed Web GIS version is an ideal tool for novice users, such as farmers, to simulate the effects of agricultural management for their farms because of its easy-to-use Web GIS interface. The NAPRA WWW system provides an easy to use WWW interface and uses spatial and relational databases to simplify the process of preparing model files. Thus, the NAPRA WWW systems now can be effectively used for nutrient management as well as pesticide management to identify the least impact agricultural management practices.

National Agricultural Pesticide Risk Analysis (NAPRA) World Wide Web (WWW) 시스템 (http://danpatch.ecn.purdue.edu/${\sim}napra$)은 다양한 영농방법에 따른 농약과 영양물질의 지표수/지하수 유실량을 웹에서 모의하고자 개발되었다. 단일 토양에 대해서 모의할 수 있는 Single Field 버전의 많은 기능이 개선되었고, 행정구역/수계 경계에 대해서 모의할 수 있는 County/Watershed 버전을 확장시켜, Web Geographic Information Systems (GIS) 버전의 NAPRA 시스템을 개발하였다. Web GIS 툴을 이용하면, 모의하고자 하는 지역을 마우스로 디지타이징 한 후, 그 지역에 대해서 영농방법에 따른 영향을 모의할 수 있다. 모의결과를 웹브라우저를 통해서 지도로 보여줄 뿐만 아니라, 그 결과를 데스크탑용 GIS에서 사용할 수 있는 포맷으로 제공한다. 모델을 운영하기 위하여 방대한 양의 입력자료가 필요하고, 일반 사용자가 준비하기 힘든, 데이터들이 있는데, NAPRA WWW 시스템은 이러한 입력자료를 서버측 GIS 데이터 베이스, NAPRA 데이터 베이스, 강우 및 온도 모델 예측치 에서 추출하여 모델을 운영한다. 또한, 모의결과를 방대한 양의 텍스트 파일이 아닌, 차트나, 테이블, 또는 지도형태로 보여주기 때문에, 농부와 같이 전문지식이 없는 사람이 이 시스템을 이용하여 여러 가지 영농 방법 중에서 환경 친화적이면서 경제성을 유지 할 수 있는 최적관리기법을 찾아낼 수 있다.
