| 摘 要： | 绿化覆盖面积是评价园林城市绿地质量的基础数据,本文针对城市绿化覆盖面积的概念,在对SPOT5多光谱影像进行光谱分析的基础上,构建了差和比指数和加和指数两模型,两模型作为新的波段,结合植被分区特点参与分类,提取城市绿化覆盖面积。通过精度评价,可以确定该技术能达到较高的精度水平。 |
| 关 键 词： | SPOT5影像 城市绿化覆盖面积 植被指数 决策树法 |

| Abstract: | Classification is often based on fused image of pan and spectral images to obtain information.Contrast to fused image,multispectral image has no information degradation.At the same time,vegetation indexes could be constructed to improve objective identifiability.Green coverage area is basic data for urban green space quality evaluation.In this paper,SPOT5 spectral characteristics were analyzed.Two indexes,ratio of difference and sum index and sum index were put forward and calculated.With the two new indexes and multispectral image,combining vegetation distribution characteristic,green coverage was obtained.The result has fine classification precision. |
| Keywords: | SPOT5 image urban green coverage area vegetation indexes decision tree algorithm |
