Abstract

Remote sensing is important as a new technology for collection of geographic data for GIS on the one hand and as user's reference spatial data for scientific analysis on the other. In this paper, emphasis is placed on the importance of linking remote sensing raster data to GIS vector data to create IGIS. The application of IGIS is of great value in a variety of applications, such as information classification and environmental modeling. It is evident that remote sensing and IGIS complement each other, and both progressed independently and separately, especially in the early days. With linking the technology, concepts and theories of both in IGIS, more advanced and up-to-date information systems can be created for use in real applications. Almost all projects that currently use satellite data or deal with environmental data benefit from development of IGIS.
