摘要
以四川省丹棱地区地理国情普查生产为例,阐述了基于高分辨率机载合成孔径雷达(SAR)影像,利用机载SAR处理技术提取地理国情普查中地表覆盖分类要素与地理国情要素的过程与方法。研究表明,机载SAR技术在多云雾地区地理国情数据获取方面具有显著优势。
Taking the production test of geographical conditions census in Danling Area for example,based on high-resolution airborne synthetic aperture radar(SAR)images,this paper used airborne SAR processing technology to extract the elements of land cover classification and the geographical conditions in geographical conditions census.The result shows that airborne SAR technology has a significant advantage for geographical conditions data acquisition in cloudy and fog area.
