外文翻译---GIS在中国的发展前景 Perspectives on GIS Development in China Researches and applications of Geographic Information Systems (GIS) in China started in the early 1980s. In the early period, the development of GIS was mainly depended on the progress and applications of remote sensing, aerial photography, as well as computer aided design (CAD). In recent years, with the development of GPS and Internet technology, GIS has being developed vigorously in the country. Looking ahead to the 21st century, a new era of Digital Earth and Cyberspace is coming, which will provide a great opportunity as well as a challenge to the Chinas GIS circles. 1. Progress Pace of GIS Researches of GIS in China can date back to the early 1980. At that time, a remote sensing application project was being carried on in Southwest China and using GIS method integrated with remote sensing data to solve the area measurement automatically was initiated. After the first successful test of GIS, a proposal to start GIS research was proposed in the Chinese Academy of Sciences (CAS). Since then a great success has been achieved both in research and application of GIS in China. While its history or progress pace can be divided into four periods. From 1981-1985, it is the initial period of GIS in China. During this period, GIS was mainly keep in research and experimental stage, a number of scientists in CAS and some high learning institutes started to follow the tracks of GIS development in world. With the support of the State Science and Technology Commission (SSTC) and CAS, a number of research projects were initiated and conducted, leading to build up some typical case information systems. In this period five systematical and experimental researches had been conducted. Those are geo-data capture methods,regional information system modeling, national basic geographic databases building, development of geo-analysis software and national geographic data standards and specifications.
