Abstract
The color Landsat Image Map of China has been compiled on the scale of 1:1,000,000, which consists of 584 scenes of Landsat MSS imagery acquired in 1970's. reasonable mapping design and multiple optical processing methods are used. The map has concordant color and macroscopic characteristics, which shows lively the physiographic outlook of China. It has vast applied and academic value.
Introduction
The compilation of color Landsat image Map of China has been successfully finished on the scale of 1:1,000,000 based on accumulation of science and technology, and experience and data over several years. It is the largest color mosaic map in China with 4.5 m high and 5.5 m wide. Reasonable mapping design and multiple optical processing methods are used in compilation. The objectives of compilation are for systematically study of the development and evolution of physiographic and environment in China, the interaction of natural elements, the relationships between environments and economic development, and for developing natural resources reasonably and setting up better eco-environment.
The characteristics of the map, the compilating procedure and the scientific value have been described in this paper.
