Abstract This paper introduces the system for extracting and mapping of city green space based on aerial remote sensing data, including the method of city green space extraction, green space statistics, accuracy analysis and transformation from vector to raster. Aerial remote sensing data of East China Normal University is used to examine the system, the result showed that the system can quickly figure out the distribution and amount of green space, and the accuracy reaches over 85 percent.
