基于 WorldView-2数据和支持向量机的红树林群落分类研究
Mangrove Community Classification Based on WorldView-2 Image and SVM Method
摘要
Abstract
Using remote sensing technology in Mangrove Community Classification is very significant for surveying,taking advantage of and protecting Mangrove resource.In this study,based on the spectrum characteristics of mangroves,vegetation index and texture information calculated from WorldView-2 satel-lite imagery,we used object-oriented classification method,SVM (Support Vector Machine),in con-junction with field surveys to map mangrove forest at communities’level in Daweiwan District,Qi’ao Is-land,Zhuhai.The single-scale and multi-scale classification were also compared.The results indicated that WorldView-2 data,a very high-resolution satellite remote sensing imagery with 8 bands are very suit-able for mangrove forest classification using object-oriented and SVM method.The overall accuracy and Kappa indices for mangrove forest classification at the species level in the study area were 84.2% and 0.794 for multi-scaled analysis and 69.8% and 0.616 for the single-scaled.关键词
