| 摘 要： | 选择2007—2009年的TM影像、CBERS影像、P5、中国资源卫星、环境减灾卫星等13景高分辨率卫星遥感影像进行预处理后,提取了东居延海水面面积,但MODIS影像解译东居延海水面面积总体偏小,最大误差达13.3%,平均误差为4.9%。通过建立高分辨率影像与MODIS影像解译东居延海水面面积修正模型,对MODIS影像解译结果进行误差修正。结果表明:修正后的MODIS影像解译面积总体精度有较大提高,最大误差为5.8%,平均误差为2.6%。

| Abstract: | The paper extracted the East Juyan lake surface area by pre-processing 13 high-resolution images of the remote sensing data of TM,CBERS,P5,China Resources Satellite and other Environmental Mitigation Satellite in the period of 2007-2009.However the East Juyan lake surface area of MODIS imagery interpretation was smaller in general,the maximal error was 13.3% and average error 4.9%.This paper corrected the result of MODIS image interpretation by establishing a correction model of the East Juyan surface area ... |
