空间建模在遥感图像处理中的应用

Application of the Spatial Modeling Language in Remote Sensing Image Processing

空间建模语言是一种模型语言,是ERDAS IMAGINE中所有GIS分析和图像处理功能的基础,可以为各种各样的应用编写空间程序模型,实用程序模型,可以产生最适合于数据特征和应用目标的算法。文中以TM数据为例,基于空间建模工具和条件函数制作专题分类图像,主要介绍了空间建模在遥感图像处理中应用的方法和步骤。

The spatial modeling language is a kind of model language and is also the base of GIS analysis and image processing function in the ERDAS IMAGINE,which can not only compile spatial program models and practical program models for all sorts of applications,but also create the algorithm most suitable for data characteristics and application target.Taking the TM data as an example and based on use of the spatial modeling tool and conditional function to make the thematic classified image,the paper highlights briefly the method and procedure applied by the spatial modeling language in remote sensing image processing.
