| 摘 要： | 针对图像软件系统工程项目中涉及的多源遥感数据的预处理问题,研究了当前几种典型卫星数据的不同存储格式,提出了对各种遥感数据进行解析的方法.通过对地理空间数据抽象库( GDAL)原有功能进行完善和扩展,并重新编辑发布动态链接库( DLL)版本,设计了多源遥感数据在GDAL框架体系下的统一解析模式,实现了遥感数据解析结果存储为项目中通用的统一数据格式(如Tiff格式),为后续的遥感数据处理和定量遥感数据产品的生产提供数据基础和技术支持.

| Abstract: | Aimed at the problems of multisource remote sensing data pre-processing involved with the image software system developing project,several present typical satellite data saving formats are studied.The methods of the multisource remote sensing data analyzing are presented.The original GDAL(geospatial data abstraction library) functions are consummated and expanded,and the DLL(dynamic link library) version is released.Based on these,the scheme of unified analyzing of the multisource remote sensing data in GDAL frame system is designed and the purpose of saving the analyzed results as a unified data format in the project is realized.The results will provide data foundation and technology supports for the yield of quantitative remote sensing products and the next data processing course. |
