典型遥感影像分类方法适用性分析
Scalability analysis of typical remote sensing image classification method
摘要
Abstract
The classification is an indispensable step to extract information from remote sensing images.Selecting appropriate classifier is very important to improve the classification accuracy.How to choose suitable classification algorithm for specific research is an urgent problem to be solved.An area in the central of Beijing is selected as the research area,the GF-1 data and Landsat 8 data are applied,and the most commonly used and relatively high classification accuracy supervised classification methods such as minimum distance method,maximum likelihood method,and support vector machine method are applied,resperctively.The research is divided into five categories:forest land,grassland,water body,bare soil and buildings.The comparative analysis for the classification results in terms of spatial distribution,area,and accuracy are conducted.The results show that the selection of the classification algorithm mainly depends on the characteristics of the ground features in the study area,among which the minimum distance classification has a higher accuracy when applied to the area with large vegetation cover,the maximum likelihood classification is suitable for the area with many buildings,and the support vector machine has high universality to all kinds of objects.关键词
