| API |
Application Program Interface (API). An API is a set of system calls or routines for application programs to access services from operating systems or other programs. An API allows your program to work with other programs, possibly on other computers. API is fundamental to client/server computing. |

Command and Control. Command and control functions are performed through an arrangement of personnel, equipment, communications, facilities, and procedures employed by a commander in planning, directing, co-ordinating, and controlling forces and operations in the accomplishment of a mission. |
| COP |
Common Operational Picture - A single identical display of relevant information shared by more than one command. A common operational picture facilitates collaborative planning and assists all participants to achieve situational awareness. |
| COP-IDS™ |
Common Operational Picture - Image Display Server |
| DGPS |
Differential Global Positioning System - a technique to improve GPS accuracy that uses pseudo-range errors measured at a known location to improve the measurements made by other GPS receivers within the same general geographic area. |
| DNC |
Digital Nautical Chart, a vector product from National Mapping and Imagery Agency |
| DTED |
Digital Terrain Electronic Data |
| ECDIS |
The Electronic Chart Display and Information System (ECDIS) is the new set of rules and performance standards developed by the International Maritime Organization (IMO) that allows a civilian ship to safely navigate without paper charts. |
| ECDIS-N |
ECDIS-Navy (ECDIS-N) is the term that defines the U.S. Navy's performance standard for ECDIS to be employed on Navy vessels. It calls for a transition of the entire U.S. Navy fleet from paper based charts to electronic digital charts. ECDIS-N requires the use of Digital Nautical Charts (DNC) produced by NIMA. |

| GIS |
Geographical Information System (GIS) A computer-based system for capturing, storing, analysing and displaying locational data. |
| Geospatial Data |
Geospatial data is information that identifies the geographic location and characteristics of natural or constructed features and boundaries on the earth. This information may be derived from, among other things, remote sensing, mapping, and surveying technologies. |
| GPS |
Global Positioning System a system for providing precise location that is based on data transmitted from satellites. |

| Photogrammetry |
The use of stereo pairs of aerial photographs (or satellite images) to produce geometrically correct maps. |
| Remote sensing |
Acquiring information about an object at a distance, using aerial photography, radar, and satellite imagery. |
| S57 |
A Marine Vector Chart Standard |
| SUSA |
Small Unit Situational Awareness soldier system |
| S-VDR |
Simplified Voyage Data Recorder. The marine equivalent of an aircraft’s
“black box”. Allows ship operators to collect valuable ship data and record it to a highly protected storage capsule. Information from a ship's navigation sensors and control systems, radio traffic, bridge microphones, integrity sensors and alarms are captured and stored for future use. |
| Spatial data |
Data about the location or the geometric characteristics of geographical features. |
| TOD |
Tactical Ocean Data. TOD is a vector-based digital product that portrays seafloor configuration, particularly in areas deeper than 183 meters (100 fathoms) in a format suitable for subsurface navigation. It is used in conjunction with the Digital Nautical Chart (DNC™) for complete navigation information. |
| UAIS |
Universal AIS. Equipment that transmits the location and identity of its ship as well as additional information about the vessel, such as its heading, speed, and safety-related data. |

| WECDIS |
Standard for Warship Electronic Chart Display and Information System This classification defines a standard for WECDIS in order to ensure that all electronic chart / geographic information systems fitted on warships from NATO nations will provide a minimum common set of functions to the operator and accept digital data in common international approved (IMO as well as NATO) standard formats. It specifies performance standards with respect to optional functions on these systems. Endorsed by AC/322(SC/8) on 1st week of March 1999. STANAG is in ratification and implementation process. |
