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。

lava dome：熔岩穹丘
熔岩穹丘(Lava Dome) 熔岩穹丘是圆形的、边缘陡峭的丘状物,是由于高粘度的火山熔岩(英安岩或流纹岩)堵塞喷火口所形成. 熔岩穹丘顶端一般无火山口,从地下涌来的岩浆挤入熔岩穹丘内部,从而引起熔岩穹丘突起变形. 熔岩穹丘的表面是已经冷却的坚硬的熔岩,

Pumice：轻石
与喀斯喀特山脉其他火山类似,圣海伦火山呈圆锥形,由熔岩、火山灰、轻石(pumice)和其它沉积物交替层叠堆积而成. 圣海伦火山还包括玄武岩和安山岩层,几个英安岩火山穹丘即为从中喷发形成. 最大的一个火山穹丘构成了老的山峰,
