摘要
选择Landsat 1986.6和2002.6两个时期的TM影像,经过多波段彩色合成处理,在分析居民地等多种地物的光谱特征及谱间特征的基础上,建立了居民地信息提取的光谱模型,提取并制作了两个时段的居民地分布图.在此基础上,简要分析了胶东半岛龙口市近20年来居民地动态变化的特点.
Choosing TM images in 1986 and 2002, through multiband color composition, the spectrum models for extracted information of residential areas are established, and the distributing maps of residential areas in 1986 and 2002 are made.
