The technology of microsatellite is an important achievement of high integration of space technology, electronic technology, computer technology, optics technology and remote sensing technology, many countries, especially west countries are interested in its development and application. The Space Center of Surrey University of British has developed and designed more than 20 microsatellites for more than 10 countries. Some institutes of our country have a plan of cooperation with Surrey University in absorbing microsatellite technology. Through analyzing the imagery qualities and features of the data that acquired from microsatellite,authors consider it will have good prospects in global disaster and environmental monitoring, agricultural evaluation and resource survey in the near future. In China, developing itself microsatellite technology will have a strong promotion for its space remote sensing application in social sustainable development.
In view of the priority project of the western development, this paper deals with the predominance of remote sensing technology which applied in the investigation and development of western mineral resource, land resource, water resource as well as ecological environment monitoring and basic installations establishment, illustrates a large number of examples of the achievement of the remote sensing technology in land resources investment, engineering geology, environment geology, disaster geology and so on, expounds what problem the technique can solve and how to solve, analyses the technique's development direction, and regards the remote sensing technology is one of the most important technique in the western development.
When researching into the relationship among underground water, soil water and rainfall, combining with climate data, we put forward the view that soil water is mainly supplied by under ground water. Because microwave is sensitive to the water content in soil, it's possible to probe water resource underground with radarsat remote sensing. With this idea, we select an arid area located in Alashanzuoqi Inner Mongulia for test, the result is reasonable and good.
The characteristics of remote sensing image, geochemistry and radioactive spectrum of coal-bearing series and coal rocks in Jixi Cooperative District have been proposed on the base of its hydrocarbon-forming and gas gathering process. As a result, the comprehensive geological characteristics of coal bed gas in this area has been proposed, and the ability of hydrocarbon-forming and gas gathering surrounding this area has been studied in detail.
In Nanchang area with widespread and thick Quaternary alluvia, two kinds of neotectonism are clearly identified by remote sensing. Vertical up-and -down makes Gan river and Fu river transfer from west to east, while horizontal drift causes extension and open of Qinlan lake and Junshan lake. The two kinds of neotectonism have trigged rockfalls of lake and river banks which should attract attention of the government.
This paper dicusses the technological train of thought and the use of prospecting model method related to provenance field-ore-forming node-remote sensing anomaly in detail. Three type of provenance field, three type of ore-forming nodes and two type of remote sensing anomalies have been proposed. This method is very useful and affective in the actual ore prospecting works.
Satellite remote sensing technology is developing rapidly worldwide. New sources of the remote sensing data and digital image analysis techniques can be applied to the field of oil and gas exploration. This study examines and evaluates multi-sensor remote sensing data in the context of a comprehensive geology investigation in the Loess Highlands of the Ordos Plateau in China. Implications for further investigations are discussed.
It is very potential technique to Extract different rock information using hyperspectral remote sensing data. This paper describes an application example by different image processing methods according to different rock spectral feature of MAISdata, and then it expands the capacity from qualitative analysis to quantitative extraction.
Remote sensing technology, which is characterized by producing imagery on multi-platform, different temporal and spatial resolution, has greatly improved mankind's capability of acquisition, processing and application of spatial information. The increase of spatial data sources and the development, applications and industrialization of spatial information technology are urging the need of spatial data sharing and exchanging. Based on a brief introduction on the China Spatial Information Network (CSI) and its database system, the CSI Spatial Science and Technology Information Database (SSTID) management system was designed and implemented in this paper.
Land is the material base on which human life and economy development depend. With the growth of population, the contradiction between human and land use becomes more and more sharp. How to use the limited land rationally becomes a serious problem, and it has great effect in human life and social development. ULISis such a system that people can make rational use of land by it and can make the development project accord with land use. There is a basic framework of ULISin this essay, and it is concise and explicit.
With the deep and wide application of map data in many fields, as the basis and premise, map data management is more important. This paper describes how to realize map data management with SDEof ESRI, the application changes the traditional map data management method. The new method not only improves the security of map data, but also makes management and use of map data easier, at the same time, it make the map data share in local network.
