The technique of space remote sensing is developing rapidly in recent years. Many countries have been launching satellites. The high resolution little commercial satellite and the radar satellite have become the important information resources of remote sensing. High spectral resolution technology are still the main developing tendency of now and next century. Facing the new opportunity, the authors put forward some oritentation of application and research using remote sensing information.
This paper using TMimage to analyze the opening direction of craters and the flowing direction of basalt, drawing out water pooling basins on the basalt mesa, so as to determine the area strong rich in water in basalt area of Cenozoic, where are water exploiting object areas.
In this article, the author uses thermal infrared image to interpret in great detail the potash anomaly in Luobupo salt lake area, gains a series of thermal characteristic information of the potash anomaly area, discusses thermal field variety and its meaning within salt lake area, explains for formatting mechanism of thermal infrared information related with the potash anomaly. Finally, the thermal infrared image pattern for potash anomaly is supposed, which is the new method of finding potash anomaly in modern salt lake area using remote sensing technique.
Land use change monitoring is a long-term task, its purpose is to find out about the land use change periodically or non-periodically and provide information for planning and administering. Application of TMdata to land use change monitoring was introduced in this paper. Post-classification comparison method was taken. The measure to reduce enlarged change range is to improve the precision of classification and calibration of multi-temporal Landsat data. In this way, the classified result for mono-temporal TMd ata can compared with others for any another mono-temporal TMdata, then the land use change information can be obtained.
In order to analyse the data quality of the CBERS-1 satellite, the authors compare the CCDimage of the CBERS-1 satellite with the TMimage of the Landsat-5 satellite in detail in Zhongdian area, Yunnan Province according to the spatial resolution, geometric distortion, radiation accuracy, clarity and noise.
On the basis of processing, interpretation and field inspection of fusion images of TM and airborne γ-spectra data, the potash-alteration zones and low-thorium secondary granitic intrusions are recognized and their distribution information are extracted in Xiazhuang uranium orefield. It is proved that the uranium metallogenesis has close genetic and spatial relationship with potash-alteration fault zone and low-THsecondary intrusion. In addition, according to clue of ringed image and based on researching into the event of dome structure uplift that generated after major intrusion consolidation, it is pointed out that the mantle plume had been existed in this region. The mantle plume tectonic process caused a series of geological processes and it is the essential background for forming the uranium orefiled.
In this paper, the affect of shield on afforestation distilling is discussed and the formula of shield is derived based on practice. Away to realize shield computer is given. Lastly, some analyses of the way and results are discussed.
This paper is about the building of metamorphic rock mapping unit basing image cluster and image group through analysing remote sensing image feature in hypometamorphic rock area and the remote sensing geological interpretation of metaporphic supercrustal rock and plutonite in the work area. It also sums up remote sensing geological mapping method and technology, which has great meaning in directing metamorphic rock mapping in the work of regional geological survey at scale of 1:250000.
On the basis of remote sensing image, the feature of kinematics and dynamics of mudflow in complex valley is analyzed in this paper. The author thinks that the movement state of mudflow in a minor valley is unform motion, and pulse form in a main valley. This movement state of mudflow in a valley is from the accumulation and release of the motion energy of mudflow itself. The accumulation and release of motion enetgy are determined from the conditions of geological environment of main valley sides.
The combination of GISand RStechnology is the trend of integration in spatial analyse. This paper discusses the system design and management in city green information system with remote sensing, including green information extracting, classification, overlay and information integration. Then, it gives the revised NDVImodel by analysing the method of green information extracting. It also puts forward several proposals of quality control in management of large green information system.
Changbai mountain volcanic apparatus information system been built up based on system designing and analysing, it consists of five models. The database was made of VBlanguage, analysing system (two models) were realized by interface designing, structure analyzing and writing program. Volcanic structure system and lithology and lithofacies system were up on Mapinfo software.
This paper introduces the application of RSand GISto Environmental comprehensive evaluation in Shenfu—Dongsheng area. Using RSas basic information source, considering the environmental characteristics of this area, the environment comprehensive evaluation system is established. The system includes ten data layers such as environmental pressure burden, environmental problems and environmental potentialities. Incorporating expert knowledge administrative level analyses are used for all element weight defining and sequence arrangement. Taking GISas technological support, spatial and temporal change analyses of each topic are carried out. Comprehensive evaluation models of environment are established. Environmental qualities of the area are objectively evaluated in detail.
