摘要:

利用2001年胶州湾RADARSAT-1数据,探讨了SAR影像在海水养殖面积监测方面的可行性。选择适当成像参数、天气与海况等环境条件下成像的遥感数据,进行SAR影像的几何校正、图像增强等图像处理,提取养殖区面积信息。选取胶州湾西北部大沽河口至红岛间的海域作为实验区,对处理后的影像进行养殖区面积的提取,结合常规调查数据对该海域养殖类型变迁分析,结果表明1999到2001年间有4.634×10⁶m²海域由底播养殖区转变成水面养殖区。

Extracting aquaculture area with RADASAT-1

Abstract:

This study presents the feasibility of RADARSAT-1 data for monitoring aquaculture area. The data are received with appropriate imaging parameters, weather and sea conditions. The methods of geometric rectification and image enhancement of SAR images are used for the extraction of aquaculture area. The region between Hongdao and the mouth of Dagu River was selected as a study area for monitoring. Compared with historical data, the result showed that there was about 4.634×10⁶m² area which has been converted from bottom aquaculture to surface one from 1999 to 2001.

Key words: aquaculture, RADASAT-1, extracting
