Remote sensing information science: Progress and prospect

Abstract

The theoretic basis, objectives and content of remote sensing information science are described in this paper. The development of remote sensing information science has resulted in fundamental changes in the fields, objectives and methods of geoscience research, which is a sign of the revolution in the acquisition and analysis of geoscience information, and the blossoming of a new discipline. The theories, technologies and methods of remote sensing information science are widely applied in the development of the national economy. They play an important role in the investigating, monitoring, analyzing, estimating and forecasting of resources, environment and disasters. The developmental trends of remote sensing information science are outlined. It is pointed out that natural resource and environment information is an important national strategic resource, and the construction of a national resource and environment information system is of great importance.
