Research on the extracting Urban Green Space Information Using Remote Sensing Data
Abstract:In this paper,the author studied the research on the extracting urban green space information using remote sensing data,at first,the author summarized the extracting methods based on the using of the aerial photographs、the satellites images 、high resolution images and hyperspectral remote sensing data,then analysis the problems existed in extracting the urban green space information,finally the author proposed that the unmixing pixel is the promising way to extract urban green space.
Keywords: remote sensing;urban green space;information extraction;mixed pixel decomposition
