Users Manual for the Surface Currents Data Base (SCDB) Management System (SCDBMS) Version 1.0
Abstract:
The SCDBMS provides access to the Surface Current Data Base SCDB which is maintained by the Naval Oceanographic Office NAVOCEANO. The SCDBMS incorporates relational database technology in providing seamless access to surface current observational data. The SCDBMS is an interactive software application. A graphical user interface GUI supports user access to its functional capabilities. The SCDBMS operates exclusively on surface current observation data. Each observation is composed of a location latitude and longitude, a date month, year, day, a classification code, a source code, the current speed in knots and direction in degrees from which the current is flowing. The order and arrangement of the data elements contained in a surface current observation file are illustrated in Figure 1. Header information is neither necessary nor included in surface current observations data files. The importexport data files are written in ASCII format SCDB ADMIN. Within the database, surface current data is stored using the generic latitudelongitude time LLT data structure of the Navy Environmental Operational Nowcast Systems NEONS
