| Abstract: | The launch of the high resolution remote sensing satellite provides an efficient way for urban green space information extraction research currently .To get the most out of the high resolution remote sensing data seems to be very important in modern urban planning and ecological environment evaluation . By using a complete remote sensing engineering example in ENVI ,it gives the introduction about high resolution remote sensing data management ,reasonable arrangements of extract procedure with high resolution remote sensing data ,object-oriented information extraction in FX module ,etc .Thus ,the total quantity of the urban green space and the present situation of the distribution can be made in an all-round and fast way ,and it also provides a reference about green space system planning and daily management , w hich has important implications for the construction of the ecological city . |
