基于遥感图像的城镇用地信息提取方法研究

如何快捷、准确与客观的提取城镇用地信息,以获得城镇用地的分布范围和面积资料,是有关城镇问题研究中的一个基本问题。利用遥感技术可以有效的解决这个问题,从城镇用地的遥感信息机理分析入手,根据各地物不同的光谱信息值,深入研究了基于遥感影像下的城镇用地的信息提取方法,并对提出的提取方法进行了若干讨论。研究结果表明,与传统的计算机分类方法和人工目视解译的屏幕数字化方法相比,本文所探讨的方法是一种行之有效的方法。

Extracting Urban Land Use Based on Remote Sensing

It is a very important problem which quickly,correctly and objectively obtain the area of land use.With the remote technology,it is very easy to deal with this question,In this paper,according the feaure of remote sensing image and different kinds of something of land covers,a deep research on the classification of urban use based on remote sensing,finally some discussions are made for these methods.The results was compared to the manual interpretation and computer classification,this proposed new method has a number of anvanges over the conventional supervised classification method.
