Study of Polluted Area Mapping System Based on Satellite Imagery

This paper mainly focus on managing and processing graphical data and attribute data relative to polluted are abased on Google Earth platform that gets rich geo-data to you with amazing speed and full context. The processes of importing, organizing, visualizing, editing and exporting of geographic entity such as polluted area are investigated in detail. KML with a tag-based structure acts as an effective interface for data storage and conversion. Google Earth Plug-in and its API are used to developing relevant functions to organize and manipulate spatial data. Essential algorithms on spatial analysis are designed for editing graphics. And satellite imagery in Google earth viewer plays an important role in navigation and location for geographic entity. A prototype system with primary operating functions is realized with Microsoft .NET platform and it can be used for polluted area mapping in power supply enterprises.
