What does CGRS mean in UNCLASSIFIED
CGRS stands for Common Grid Reference System. It is a system used to uniquely identify locations on the Earth's surface. The CGRS is based on a grid of lines of latitude and longitude, which are imaginary lines that run parallel to the equator and the poles, respectively.
CGRS meaning in Unclassified in Miscellaneous
CGRS mostly used in an acronym Unclassified in Category Miscellaneous that means Common Grid Reference System
Shorthand: CGRS,
Full Form: Common Grid Reference System
For more information of "Common Grid Reference System", see the section below.
Key Features of CGRS
- Two Coordinates: Each location in the CGRS is identified by two coordinates: an easting and a northing. The easting represents the distance of the location from a central meridian, and the northing represents the distance from a central parallel.
- Units of Measurement: The coordinates in the CGRS are typically expressed in meters.
- Different Zones: The CGRS is divided into different zones, each of which covers a specific geographic area. The zones are identified by a letter and a number, such as "Zone 30N".
- Datum: The CGRS is based on a specific datum, which is a reference point used to establish the origin of the coordinate system.
Advantages of CGRS
- Accuracy: The CGRS provides a high level of accuracy for locating positions on the Earth's surface.
- Uniqueness: Each location in the CGRS has a unique set of coordinates, which allows for precise identification.
- Global Scope: The CGRS is used worldwide, making it easy to locate and share geographic information across borders.
- Compatibility: The CGRS is compatible with other coordinate systems, such as the Global Positioning System (GPS).
Essential Questions and Answers on Common Grid Reference System in "MISCELLANEOUS»UNFILED"
What is the Common Grid Reference System (CGRS)?
The Common Grid Reference System (CGRS) is a coordinate system used in the United Kingdom to define the location of points on a map. It is based on the British National Grid (BNG), which was introduced in 1936. The CGRS is a two-dimensional system, with eastings and northings used to define the location of a point. Eastings are the horizontal coordinates, measured in metres from a central meridian, while northings are the vertical coordinates, measured in metres from a central parallel.
What is the difference between the CGRS and the BNG?
The CGRS is a more recent version of the BNG. The main difference between the two systems is that the CGRS uses a different central meridian. The BNG uses the Greenwich Meridian, while the CGRS uses the Airy Meridian. This means that the eastings in the CGRS are slightly different from the eastings in the BNG.
How is the CGRS used?
The CGRS is used for a variety of purposes, including:
- Navigation
- Mapping
- Land surveying
- Emergency services
- Military operations
Final Words: The CGRS is a widely used and accurate system for identifying locations on the Earth's surface. Its unique coordinates, global scope, and compatibility with other systems make it a valuable tool for a wide range of applications, including navigation, mapping, and surveying.
