Visual interpretation´s applying on the construction of urban and rural green database based on SPOT5 image: A case study in Haidian District in Beiing

The investigation of urban and rural green space is the basic premise for construction of green space system planning. However, traditional investigation method that based on artificial survey primarily has many problems, such as too much workload, long time-consuming. Here, we take Haidian District in Beijing as an example, classifying urban and rural green space, establishing visual interpreting marks based on SPOT5 full-color image, interpreting green space according to the visual interpreting marks, and verifying and filling data when survey in field. At last, we complete basic data collection for database construction of urban and rural green space in Haidian District. This research will provide an important reference for further urban and rural green space investigation.
