The Application of Web-Based GIS and GPS Technology to Assess Water Quality in Michigan

摘要

A web-based GIS provides simplicity and interactivity such that some simplified functions of the watershed management can be open in Internet/Intranet for specific users or general public users. A palm-size GPS device provides location information, x and y coordinates, in the observation site that can bring all associate data of physical, chemical, and biological conditions. This paper presents an application of web-based GIS and GPS technology to assess water quality, by using a case study of comparing and contrasting watersheds in Michigan.
