What does WKID mean in NETWORKING
Well Known ID or WKID is a unique code used to identify different spatial reference systems in GIS software. The codes are provided by the European Petroleum Survey Group (EPSG) and can be used for any type of geospatial data, from cartographic projections to local datums. The EPSG WKID can be used with many different types of software and platforms including ArcGIS, AutoCAD, QGIS, GeoServer and PostGIS. WKIDs provide an easy way to share spatial references across organizations as well as within organizational GIS departments.

What does WKID Stand For?
WKID stands for Well Known ID. It is a code that is used to identify different spatial reference systems in GIS software. A WKID is also sometimes called an EPSG code, which stands for European Petroleum Survey Group iSOG (EPSG).
What Is a Well Known ID?
A Well Known ID (WKID) is a code that is assigned to each type of coordinate system that is supported by a Geographic Information System (GIS) software package. These unique codes are provided by the European Petroleum Survey Group (EPSG), who maintain an authoritative database of all spatial reference system information. Each code contains information about the projection parameters, geographic area covered by the coordinate system, and associated datum information such as ellipsoid model name and datum parameters.
What Is the Purpose of a WKID?
The purpose of a WKID is to provide an unambiguous way to specify which coordinate system should be used when working with geospatial data in GIS applications. It allows users to store data in the correct format regardless of where it originated from or what software was used to create it initially. This eliminates confusion caused by mixing up units or not understanding the source of projected coordinates when sharing datasets among various institutions or organizations that use different GIS solutions. Having access to this information leads to better consistency of results and fewer errors over time.*
Essential Questions and Answers on Well Known Id in "COMPUTING»NETWORKING"
What is a WKID?
A Well Known Id (WKID) is a unique identifier or code assigned to map projections and geographic coordinate systems that have been standardized by the Open Geospatial Consortium. It functions like an international identification number for finding the correct transformation between different geographic coordinate systems.
What types of map projections does WKID support?
WKID supports all major projection types, including Lambert Conformal Conic, Transverse Mercator, Albers Equal Area, Miller Cylindrical, and Sinusoidal.
How do I know if my data uses a standard WKID?
If your data follows well-known conventions, then it will most likely use a standard WKID number. You can quickly check your dataset by viewing its spatial reference properties in GIS software such as ArcMap or QGIS.
What are the benefits of using a standard WKID?
Using a standard WKID ensures that your data is accurately represented on maps throughout different geographic regions. This allows for easier mapping across larger areas and helps to reduce confusion from differing coordinate systems. It also ensures compatibility with other datasets that use the same coordinate system.
Can I assign my own custom WKIDs to data sets?
Yes you can create custom WKIDs for specific datasets when necessary. It is important to note that these custom identifiers may not be supported or understood by other GIS programs or platforms.
Where can I find the list of available standard WKIDs?
The list of available predefined standard Well Known IDs (WKIDs) may be found on the Open Geospatial Consortium website under Spatial Reference Systems > Coordinate Reference Systems Database > WM/SRS- 94 > Predefined Identifiers (esriwkid).
Does each map projection have its own unique WKID?
Yes each different map projection has its own unique Well Known Id (WKID). For example, UTM Zone 10N has an ESRi WKI of 32610 while Web Mercator Auxiliary Sphere has an ESRi WKI of 102100.
Final Words:
In summary, WKID stands for Well Known ID and is a unique code assigned to each type of spatial reference system in GIS software packages by the European Petroleum Survey Group (EPSG). WKIDs provide an easy way to share spatial references between organisations while eliminating confusion caused by mixing up units or not understanding the source of projected coordinates when exchanging geospatial data sets between departments using various different GIS solutions.
