GIS辅助下的遥感图像分类
摘要:
本文首先简单阐述了遥感图像及其分类的意义,以及地理信息系统的特点。由于RS与GIS有着紧密的关系和很强的互支持,目前,RS与GIS集成中的一个重要任务就是将GIS数据直接纳入图像处理。本文重点介绍了在GIS的辅助下进行遥感图像分类的方法及其特点和途径,在利用GIS在进行图像分类时,加入空间关系,在空间关系辅助下训练样本,部分消除仅依赖光谱数据分类而引起的同物异谱和同谱异物造成的分类错误,提高分类精度。

This article first simply elaborated the remote sensing image and its the classified significance, as well as geographic information system characteristic. Because RS and GIS have the close relations and the very strong mutually support, at present, RS and in a GIS integration important task is brings into line with directly the GIS data the imagery processing. This article introduced with emphasis carries on the remote sensing image classification under the GIS assistance the method and its the characteristic and the way, in using GIS when carries on the image classification, joins the spatial relations, trains the sample under the spatial relations assistance, the classified mistake which the partial eliminations only relies on which the spectrum data class but to cause the same thing different spectrum and the same spectrum foreign matter creates, increases the classified precision.
