3S Integration Technology

Guidance: 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.

Principles, Technologies, and Methods of Geographic Information Systems  102

In recent years, Geographic Information Systems (GIS) have undergone rapid development in both theoretical and practical dimensions. GIS has been widely applied for modeling and decision-making support across various fields such as urban management, regional planning, and environmental remediation, establishing geographic information as a vital component of the information era. The introduction of the “Digital Earth” concept has further accelerated the advancement of GIS, which serves as its technical foundation. Concurrently, scholars have been dedicated to theoretical research in areas like spatial cognition, spatial data uncertainty, and the formalization of spatial relationships. This reflects the dual nature of GIS as both an applied technology and an academic discipline, with the two aspects forming a mutually reinforcing cycle of progress.
