The technique of digital landslide, 3D visualization and man-machine interactive interpretation were used to analyze the geomorphologic features of remote sensing images. From the characteristic of the deposit, it is deduced that the paleo-landslide was a deep and consequent rock landslide with large-scale deposit, the entire deposit of \"7.13\" landslide is similar to the paleo-landslide, and the displaced volume is 15×106m3. Based on the geology theory, this paper synthetically compared the effect of landslide between the rainfall and the water level rising. It is concluded that the main inducing factors is the first stage storage of the Three Gorges and the continuous rainfall is triggering factor. Synthetically analyzing the process of slide and the characteristic of deposit, it is deduced that the middle and front part of Qianjiangping landslide is push-type sliding while the back part is drag sliding, the pattern of deformation and destruction is front verge leading sliding-drag.","PeriodicalId":340728,"journal":{"name":"China Symposium on Remote Sensing","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123735131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main problem need to be solved is the image reconstruction from the rotation sampling visibilities. In this study we develop a Pseudo-Polar FFT algorithm that suitable for dealing with the polar sampling grid data of rotation scanning system. It takes pseudo polar grid as the conversion destination instead of traditional Cartesian rectangular grid before the Fourier inversion. The involved effective 1D interpolations and 1D-FFT routines in this imaging algorithm guaranteed a high accuracy and computational efficiency. Moreover we analyzed the associated rotation sampling scheme such as the antenna array arrangement and rotation sampling interval which have great effects on the reconstruction results. Numerical simulations are present for validating the superiority of this new imaging algorithm. Simulation results also indicated that the non-redundant plane antenna array with good linearity is the prefer array arrangement for rotation scanning system.","PeriodicalId":340728,"journal":{"name":"China Symposium on Remote Sensing","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121404464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Satellite remote sensing image can be used to illustrate the panorama of regional fractures and structures on macroscopic view. Fusion of multi-source images(especially SAR and optical multi-spectral image) is a hot spot in RS information processing and application field. A image fusion based linear structure information detection method is proposed in this paper. After introducing wavelet and wavelet packet transform and their applications in image fusion, a regional standard deviation wavelet coefficients fusion method is proposed. Experimental result shows wavelet packet fusion is better than wavelet fusion in resolution enhancement for fusion of Radarsat SAR and Landsat MSS, ETM+ multispectral remote sensing images. Study of exploring shallow-buried regional fracture information covered by Quaternary unconsolidated sediments in Hangzhou area shows the fusion method applied on SAR and optical multi-spectral RS image can improve resolution and the capability of interpret shallow-buried fractures.","PeriodicalId":340728,"journal":{"name":"China Symposium on Remote Sensing","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131844506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Along with the intensive study of LAI retrieval in remote sensing, the scale effect problem related to LAI has attracted more and more attention and has become a focus in quantitative study of remote sensing. Based on the mechanism analysis of scaling effects, the scale effect of LAI is discussed. Then, the relevant scaling model is proposed under the hypothesis of a normal distribution of surface observations. The result shows that the relative error for LAI retrieval is less than 1%.

Firstly, the preprocessed 1A level multispectral imagery and panchromatic imagery were registered coarsely based on affine transformation in this workflow using the ephemeris in metadata files. Secondly, the grid constrained feature points were extracted from the two images by improved Forstner operator, and tie-points pairs were obtained by a coarse-to-fine matching using Euclid distance and correlation. Finally, error pairs were eliminated by least median of squares (LSM). After getting enough control point pairs which were high-precision matched and distributed evenly, coarse-registered multispectral imagery was rectified in local small region based on Delaunay triangulation network. Experiments were performed on many volume images, and the results show that the root mean square errors (RMSE) of the check points are less than 0.5 pixels.","PeriodicalId":340728,"journal":{"name":"China Symposium on Remote Sensing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122740048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

How to timely acquire information about the growth and moisture content of forest fuel and climate for the whole country is critical to national-level forest fire risk forecasting. The development and application of remote sensing (RS), geographic information system (GIS), databases, internet, and other modern information technologies has provided important technical means for macro-regional forest fire risk forecasting. In this paper, quantified forecasting of national-level forest fire risk was studied using Fuel State Index (FSI) and Background Composite Index (BCI). The FSI was estimated using Moderate Resolution Imaging Spectroradiaometer (MODIS) data. National meteorological data and other basic data on distribution of fuel types and forest fire risk rating were standardized in ArcGIS platform to calculate BCI. The FSI and the BCI were used to calculate the Forest Fire Danger Index (FFDI), which is regarded as a quantitative indicator for national forest fire risk forecasting and forest fire risk rating, shifting from qualitative description to quantitative estimation. The major forest fires occurred in recent years were taken as examples to validate the above method, and results indicated that the method can be used for quantitative forecasting of national-level forest fire risks.","PeriodicalId":340728,"journal":{"name":"China Symposium on Remote Sensing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127098737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
