【摘要】 地理国情普查项目使用的高分影像质量的良莠不齐给地表覆盖数据生产带来了巨大障碍。本文剖析了目前收集到的高分影像资料的主要缺陷,如多分辨率、多传感器、多年份和跨季节,给地表覆盖数据解译带来极大的局限性;阐述了Landsat 8影像自身的特点,如像幅面积大、获取周期短、波段信息丰富,同时提出利用Landsat8影像辅助解译的思路,并通过试验验证这种方法的可行性。更多还原

【Abstract】 There are some obstacles of land cover data productioncause of the quality about thehigh resolution imageis used forgeographic conditions survey project. This paper analyzes the main defects of high current image data collected,multi-resolution,multi sensor,multi years andmulti seasonal,on land cover data interpretation has great limitations; describes the characteristics of Landsat8images,large size,shortobtain cycle,rich information,also proposes the idea ofaided segmentation and classification using Landsat 8 image,and the feasibility of this method through experiments.更多还原
