遥感 在轨定标 多场地 定标场网 数据库 remote sensing post-launch calibration multi-sites calibration-sites network database
摘要
针对多场地在轨定标新需求,采用Oracle 10g和Visual C++开发了全球定标场网数据库,考虑了数据库体系结构、多源数据入库、访问控制策略和数据库优化等关键技术,汇集了全球72°N~75°S之间103个光学定标场地、15种场地类型和7类场地参数,给出了部分场地参数的获取途径,场地反射率范围介于0.01~0.90之间,适用于太阳反射通道的在轨定标,数据库具有管理、查询、维护和应用等功能。在此基础上,介绍了场地数据的应用方法。
Abstract
Due to the new requirements of post-launch calibration, the global calibration-site network database is developed by Oracle 10g and Visual C++. Key technologies including database architecture, multi-source data processing, access control model and database optimization are considered. 103 optical calibration sites between 72°N and 75°S are selected. There are 15 kinds of site types and 7 types of site parameters. The approaches to achieving some parameters are given. The range of site reflectivity is between 0.01 and 0.90. These sites are suitable for post-launch calibration of solar reflective bands. The database has the fundamental functions of management, query, maintenance and application. Finally, the application methods of site data are introduced.
