摘要
探讨了在Landsat TM图像上进行玉米分布区域信息提取的基础上,利用MODIS数据NDVI植被指数的时间序列进行提取的方法,并以吉林省榆树市实验区为例,提取了2007年的玉米种植面积。研究结果发现,该方法提高了用单一时相landsat TM进行玉米面积识别的精度。
In this article,on the base of extraction maize planting area information in the image of Landsat TM,the time series Images of MODIS NDVI vegetation index were extracted for planting area.With YuShu research area of Jilin province as example,the maize planting area in 2007 were extracted.It was found that the method was more precise than single Landsat TM.
