论文摘要
Gaofen-1（GF-1） is the first high resolution optical imaging satellite of China primary civilian Earth observation project under the China High-resolution Earth Observation System.With the GF-1 trio launched on March 31,2018,the combined 3+1 GF-1 constellation will offer one-day revisit coverage,which provides more available high resolution remote sensing images for monitoring decametric-scale vegetation patches and long-term pattern dynamics.In this study,a panchromatic image,the original multispectral image,and the pan-sharpened multispectral image from GF-1 Panmultispectral Camera was compared to evaluate their potential for identifying the quasi-circular vegetation patches（QVPs） in the Yellow River Delta,China.The results showed that high spatial resolution was more important for identifying the QVPs than more additional spectral bands of GF-1,and the pan-sharpened multispectral image had the highest identification accuracy of the QVPs（F-measure is 64.6%）.In the future,multi-temporal pan-sharpened GF-1 images should be used to obtain higher accuracy,which is basis for studying vegetation patch pattern dynamics.
