Abstract The common methods and developing trends about the classification of remote sensing data is discussed in this paper. The merging of remote sensing with comprehansively varous information is considered an efficient may to improve the classification precision of remote sensing data under the current conditions.
Abstract The purpose of this paper is to describe the techniques of urban land use classification of TM image for land use investigation in Zheng Yuan county, Guizhou Province, where is a typical karst mountain area, with many land use types scattering in. The authors also discuss the result and its accurate, and introduce some simple methods of improving the accurate of classification. A geographical information system for land management (SK set 2.0) was set up and the result of the investigation was compared and examinated. It shows that the accurate of the investigation is good.
Abstract The remote sensing image of DAZESHAN mountains district was used to investigate in to the tourism resources. The vortex structure and its nuclear pool, vortical rape , rock slice between two vortical surface, brush structure was interpreted from remote sensing image. The research came to conclusion that DAZESHAN tourist area results from rotating and shearing. The ground survey of some scenic spots was made. Some ideas about develoment of tourism resources were presented.
Abstract From the macroscopic features of Landsat images, we can found the linear structures and circular structures that have a very clearly show on the Landsat photographs.These two kinds of structures are colsely related to the mineral, grounder waters, petroleum, earthquake and the stability of engineering etc. Therefore, It has a very important practical significance to study the theory of the linear structures and circular structures.
Remote sensing technique is specially suitable to detect and map geology structure in a mountain area. In this paper, by using a lot of new information from remote sensing imagery,structure pattern of the West Mountain Coal Field in Beijing is studied. The nappe and gliding nappe are two essential types of detachment within the coal area. Some aforementioned characteristics are dealed with such as their remote sensing image characters、distribution、geometry、genesis、evolution.The relationship between the datachments and the coal seams is payed great attention.
Four image discriminant marks of the nappe structure on the TM picture in northern part of Jiangxi Provinces are, first of all, discussed.Then, on the basis of careful interpretation and analysis of a TM digital mosaic image in the. area, a regional distribution pattern of the nappe structure is further proposed.
