摘要
结合2007年南京市园林管理局开展的绿地覆盖率普查项目实际,介绍了利用高分辨率卫星影像进行绿地识别、提取、覆盖率计算的方法以及利用城市绿地矢量GIS数据辅助进行绿地检查的技术手段。通过多源空间数据的综合应用,很好地提高了城市绿地覆盖率统计的准确性及可信度。
This article according to urban green coverage investigation project of NanJing Gardens Bureau in 2007, introduce green identification and statistic method, and check boundary of green area using GIS vector data. Applying multisource spatial data, correctness and reliability of urban green coverage rate investigation were increased.
