Analysis and Research of Intrinsic and Extrinsic Factors for GIS's Progress in Recent Years

GIS has made considerable progress in recent years. The powers of driving its development are application requirements' pull and related information technologies' push. First, the development of GIS has being tied up with users' application requirements. From simple mapping to complicated geographic analysis, from project -oriented to enterprise solution, and from desktop application to web service of geographic information, the advancement of application requirements results in the evolution of GIS architecture. Next, from a technological standpoint, GIS is evolving into place through integrating new information technologies with the full body of theory, methods, and technology coming out of the GIS community. Interestingly enough, it is GIS and the concepts of geography that will provide the conceptual framework for bringing this all together, including Internet, mobile communication and positioning, software development, and software engineering, etc. So it does, this paper detailedly analyzed and discussed the intrinsic and extrinsic factors for GIS's development in recent years from two aspects: one is the influence on GIS architecture as a result of the changing application requirements. The other one is the promoting to GIS due to the progress in information technologies.
