By TM images the linear structures, water system, the outer edge of Tianchi Volcano trachite are extracted. By the sensitivity of SAR images to geomorphology, the distribution of parasitical volcano cone and lava fornix around Tianchi volcano are interpreted. With the aerial photos the parasitical lava of Qixiangzhan, Baiyun and Bingchang stage are filtered. At the same time by orthogonal cross-course wavelet transform, texture analysis is carried on to ERS-2 SAR images, and the texture characters are filtered. On the basis of the spectrum character of multi-band of TM images, multi-band algebraic grouping is made, and the factor of texture character factor and band grouping of TM images are input to BP neural network classification model. The good classified results are received.

利用TM图像对线性构造、水系、天池火山粗面岩锥体外边缘的提取；利用SAR图像对地形敏感特性，提取了天池火山周围寄生火山锥体及熔岩穹丘的分布；利用航片对天池火山口周围的气象站期、白云期、冰场期等寄生喷发物进行了提取：同时利用正交小波变换对ERS-2 SAR图像进行了纹理分析，提取了纹理特征：根据TM图像不同波段的光谱特征，进行了波段代数组合，并把纹理特征参数与TM图像的波段组合及DEM一起输入BP神经元网络分类器，取得了较好的分类效果。

Based on survey of existing methods, in this dissertation: aimed to the reliability of stereo image matching in digital photogrammetric, a new matching strategy utilized local continuity constraints encoded by triangulation of the well-defined points is proposed; concerned with the inherent efficient, accuracy and size constraint problems of existing topographic structure extraction approach, an efficient, accurate and large scale data adapted approach based on the combination of vector and raster processes are proposed.
