Introduction: This chapter briefly introduces the basic concepts of remote sensing and global positioning system technology and their integrated application with GIS.
As a new technology to acquire spatial information in real time and objectively, remote sensing and global positioning system have become important data sources of geographic information system. By processing and analyzing the data obtained through GIS, we can extract all kinds of useful information for decision support.
This chapter mainly introduces some specific applications of 3S integration, and briefly describes its technical implementation.
