The comprehensive analytical mapping on the Chinese territory satelite
- Analytical Mapping on the Scenic Tourist Resources
With the help of the particular information provided by the remote sensing on natural landscapes, such as grotisque peaks and fantastic stones out of granite, mountain landscape of magma tic rock, meanders and gullies in carbonate rocket. the scenic tourist resources, concentrated in Beijing, have been divided into 13 tourist areas . The remote sensing analysis shows the master of the scenic differentiation laws in a particular region is the important theory and method for the researching on the mapping of natural scenic tourist resources.
- Analysis and Mapping on the Changes of Natural Environmental Elements .
The natural elements of the continent-sea distribution, river and lake systems, forest vegetation, etc. in the region have changes dramatically during the last near 10,000 years. While the structural arrangemental superpositon and mosaic relation between these elements are all reflected in the images to certein extent, so, we can analyze their space-time distribution patterns, evolution characteristics, furthermore can analyze their evolution sequence and development level. One example is the four changes of the Luanhe River system are respectively demonstrated in the images ; another is the zonally extended plains in the region for the earth crust's uplift-depression movements and accumulative mechanism plain and coastal plain from the northwest to the southeast to the southeast. During the last decades, the circular structure concentrated at large
cities has developed persistently with the rapid urbanization and the spreading of city proper. Using the high resolution images, the analytical mapping on them can be conducted through dynamic analysis, studies on the changes of functional structures of cities.
- The Regionalization and Mapping of the Metamorphic and Structural Lithofacies
The construction of the regional structural frame and the definitions and mapping of the structural lithofacies through the analysis of the linear structures in the imageries and the identification of the image indicators of metamorphic iron ores' controlling structures through the investigations on the circular structures are the new approaches are the new approaches to survey the metamorphic mineral resources of the pre-Cambrian.
- The Evaluation and mapping on the Regional Crustal Stability
According to the maximum streets direction and the maximum dangerous slipping angle, and the liquiferous degree of sandy soil, the Beijing-Tianjin-Tangshan region can be divided into the stable, relatively stable and less stable areas. The maximum dangerous slipping angle were determined through the investigations on the linear structures and their jointing relations in the images, taking the references to other geological and geophysical data, and supported by survey data of strain-stress in the region.
Conclusions
- The investigations on the Territory Satellite images of the Beijing-Tianjin-Tangshan region have first proposed their applicable technical standards. Generally speaking, the images with their scanning angles within ±42 degrees are suitable for the thematic series mapping at scale of 1:250,000.
- To apply the data of the Territory satellite and other remote sensing data with the assistance of the multi-information supplied by geophysical and other geoscientific data, to employ the analytical theories of remote sensing-geosciences, are the important technical methods for us to analytically conduct the high level thematically series mapping.
- To make advantages of the mapping achievements of remote sensing analysis and the calculated data of resources quality, through setting up the database , is the technical guarantee for us to renovate the data and make second development of them, as well as to draw maps at a high level.
- To develop the application of satellites, make us to carry out the investigations on the applied systems and their intelligence of China's resources satellites. Which are the key to develop the geosciences, environmental science and information science as united high technology. This will show that China'sd remote sensing researches in the fields of resources and environment have stepped up to a new application level.
