Progress in Research on the Application of High Resolution Remote Sensing Technique to Investigation of Urban Green Space

The application of high resolutionremote sensing technique to investigation of urban green space is one of the important fields of urban remote sensing, and it has become the main data source in urban green space investigation, monitoring and management for its high space recognition ability, wide area coverage, rough simultaneousness, short cycle of data acquisition, substitutability, and easy computer manipulation. A detailed review of researches using high resolution satellite remote sensing data (IKONOS, Quickbird) in investigation of urban green space, such as geometric transformation, data fusion, and information collection of urban green space, is conducted in this paper. On such a basis, the development trend of applying remote sensing to investigation of three dimension green quantity, urban green space and plant species composition is prospected.
