| 摘 要： | 要从TM影像上定量提取沼泽地信息就必须首先获取TM数据中的沼泽地波谱信息这个最基本参数。以2000年7月TM数据为数据源,在ERDAS和PCI等遥感软件支持下,运用灰度分析方法分析沼泽地及背景地物光谱特征,并以一条光谱采样剖面线分析沼泽地内部光谱结构。最终,建立了基于前述光谱特征的三个关于沼泽地信息的定量提取模式,定量提取了沼泽地的植被、积水信息以及与水田区别的参数,具有计算机上运算的可行性。

| Abstract: | In order to extract the marsh quantificational information from TM data, we must comprehend the spectral character of marsh in TM. The source data of study is from TM in July 2000. By the support of softwares of remote sensing such as ERDAS and PCI, the spectral characters of marsh and groundback land cover were analyzed in the way of gray scale analysis. In addition, spectral profile line of a marsh sample was drawn to disclose the spectral structure of inner marsh. Based on the spectral characteristics, three models were built for extracting quantificational information of marsh. Through these models, the most quantificational information of marsh was obtained. |
