摘要/Abstract

摘要： 研究了融合DMSP-OLS夜间遥感数据和Landsat 7地表覆盖遥感影像以改善城区边界提取可靠性的方法.首先利用DMSP-OLS数据和Landsat 7数据分别提取城市建成区边界,然后通过加权融合法对两种数据获取的边界进行融合,以获取可靠性更高的城区边界.实验验证了该方法的有效性.

关键词: DMSP-OLS夜间灯光数据, Landsat卫星影像, 城区边界

Abstract: This paper proposes a fusion approach to detect the urban boundary. Two boundaries were obtained using the DMSP-OLS night light data and Landsat image data, respectively. A proper weight was chosen to fuse these two boundaries obtained from different data sets so that reliability of the final results was improved. Experimental results have shown validity of the proposed approach.

Key words: DMSP-OLS night light data, Landsat satellite image, urban boundary
