Abstract:The data loading and organizing of China coast and the offshore comprehensive data platform are implemented by using the currently advanced spatial database management——Oracle9i ArcSDE with a full consideration of the variety and the complexity of the marine dataset.Meanwhile,a client management system with the functions of remote sensing data seamless merging oriented for this data platform,multi-data source quick querying,data extraction,image data loading and meta-data management was developed based on ArcObject COM.The main serving client is supposed to be the department of scientific researching that charges the affairs of national coastal and off-shore.This system has been applied to some routine service and is proved to be a qualified tool.
Keywords:data platform  Oracle9i ArcSDE  spatial database  ArcGIS  ArcObject COM  remote sensing data seamless merging
