基于TM影像的水体信息提取
- Title:
- Extraction of Information About Water Body Based on TM Image
- Keywords:
- water body; remote sensing; the decision tree classification
- 分类号:
- TP79;P331
- 摘要:
- 在分析各种地物在TM遥感影像中特性的基础上，采用决策树方法对影像进行分类。通过分析水体的影像特征，找出水体与其他地物之间的灰度差异，进而用关系表达式来实现水体信息的提取。
- Abstract:
- In this research,the decision tree classification was used to TM image.The water body information was extracted,the image characteristic of the water body is analyzed and the digital number difference is discovered between the water body and the other thing.
