摘　　要：基于3S的黄河口遥感分析系统涉及多数据源的集成整合,这些多源、多时相、多语义的数据包括黄河观测资料、基础地理信息资料、黄河口水文资料及遥感图像等,需要进行标准化、归一化、系统化处理。对地图投影的选择、地形图的分层与符号化、数据库管理等进行了数据整合标准的制定。基础地理数据整理包括扫描、配准、矢量化、属性的添加等;遥感数据整理包括投影信息设置、重投影或几何纠正、预处理、提取等;黄河水文观测数据需要逐文件分析,以便找出有用的数据进行整合。In the construction of the Yellow River remote sensing analytical systems based on 3S the integration of multi-resource data is involved.Those data are multi-resource,phase and semanteme,including the Yellow River hydrology observation data,basic geographic information data and remote sensing graphics.Before those data can be used in analytical system they should be standardized,unificated and systemized.We made a series of regulation for the selection of map projection,the delamination and symbolization of topographic map and database management.Basic geographic information data processing includes scanning,registration,vector quantization,and attributes-adding,etc.Remote sensing data processing includes projection information setting,re-projection or geometric correction,pretreatment,and extraction,etc.And the Yellow River hydrological data documents need to be analyzed one by one to identify the useful data to be integrated.
