摘　　要：针对城市绿化现状调查工作,设计基于高分辨率遥感影像的城市绿地信息的精细化提取方案.以WorldView 2卫星遥感图像作为城市绿化调查数据源,讨论遥感图像配准、融合、几何校正等影像预处理过程中的关键技术;引入红边因子的改进植被指数,通过基于多特征的面向对象决策树分类方法提取绿地信息,以此作为绿地空间分布参考图进行人机交互式解译,有效地保证了城市绿地信息精细化调查成果的质量.实践表明,运用本文设计的城市绿化现状精细化调查方法获得的绿地绿化覆盖信息能够达到城市园林绿化管理和规划的要求.In view of urban green space information survey,a practical method is proposed for extracting urban green space information meticulously by using high resolution remote sensing images.WorldView-2 satellite remote sensing images are used as the data source for the survey to discuss key technologies used in the process of image registration,fusion and geometric correction.In order to improve the extraction accuracy of urban green space information,an improved vegetation index considering red edge band is introduced and urban green space information is extracted by using an object-oriented classification method based on multi-features.The practice shows that by using the method proposed in this paper,the result of urban green space information meets the requirements of urban landscaping management and planning.
