The lake shore collapsing and lake basin silting of the Chao Lake are investigated and analyzed on the basis of the remote sensing data of aerialphotos and satellite images at different time. The lake shore of the Chao Lake is divided into three types according to the investigations, and their distribution and features are discussed. The present situation and effects on environment of the lake shore collapsing are investigated and analyzed, the present situation of silting of the Chao Lake is also analyzed by aerialphotos and satellite images at different time, some harness suggestions are put forward in the paper.
Radarsat is the most advanced satellite SAR system now. It has varied beam modes and offers the different type of remote sensing data products. Prior to the selection of suitable data products, the related influencing factors should be considered carefully. Focus on the interpretations of geological structure and lithology, this paper discusses and analyses the main influencing factors about data choice to the field of geological exploration as following: beam mode, Look anagle (beam position), acquisition time of the data, satellite's orbit and the level of data handling. Then proposing recommendations of the data products selection to the field of geological exploration were recommended, it is helpful to the geologicl survey by Radarsat SAR data Products.
This paper have carefully quantitatively analyzed linear structures and circular structures which came from visual explanation of remote sensing image of Lanping basin,including linear structure density(and frequency) analysis,direction-length(and frequency) analysis。And then,integrated all sorts of structures analysis with the distribution of ore-deposits(or points)and chemical anomaly analysis,the author Predicted four ore-forming favorable regions which will be very useful to further research and seeking ore-deposits.
The paper discusses three kinds of expression types of hydrocarbon-gas's feeble seepage on the basis of practical studies in north Shanxi province oil area recently years. Moreover, provides and analyses the verifications of chemical and physical exploration or drilling exploration. Authors think that a synthetically interpretation on data of remote sensing and chemical exploration or physical exploration can get a better result in oil development.
Based on analysis of engineering geological conditions with TM image, this paper introduces applications of large_scale aerophotos for investigation on engineering geology of corrective and compared route of expressway in Heshuo_Kuehe area of Xingjiang. Finally, it makes a comprehensive evaluation on route engineering geological conditions by using other methods.
Kunming City locates in plateau and lower latitude region. Heat island differs from other cities. The study of using NOAA/AVHRR 1, 2 and 4 channel data shows that the intensity of heat island in Kunming is very strong and daily variation is high. Some times the intensity of heat island in day time is higher than night.
