摘要
高分数据在各个领域使用越来越广泛,自动获取高分L1A级影像的轮廓图变得日益迫切。无法自动获取影像轮廓图给数据管理造成的种种不便,本文描述了利用GDAL库和其它第三方类库在. NET平台上自动生成高分L1A级影像轮廓图的过程,包括自动查找、解压、读取元数据、创建影像轮廓图。实现了影像轮廓的可视化,方便了高分影像数据的管理。实验表明该方法简单、可行。
Gaofen image data was more and more widely used in various fields,automatically obtaining contour maps of high-resolution L1 A images became increasingly urgent. Unable to automatically obtain image contour maps for data management caused inconvenience,in the paper,the process of establishing automatically Gaofen image footprints was introduced using GDAL and other third-party Libraries in. NET platform,including auto-searching,auto-decompressing,auto-reading meta-data and auto-generating footprints. Visualization of Gaofen image footprints was realized and the management of Gaofen image data became facilitate. The practice showed this method was simple and feasible.
