What is well-known ID?
Noun. Term used in the specialized technical disciplines of geodesy and geomatics to indicate a numbering system which indexes a diverse range of Geographic Coordinate Systems and Projected Coordinate Systems.
What is the WKID in ArcGIS?
Defines the spatial reference of a map, layer, or task parameters. This indicates the Projected Coordinate System or the Geographic Coordinate System used to locate geographic features in the map. Each projected and geographic coordinate system is defined by either a well-known ID (WKID) or a definition string (WKT).
What WKID 102100?
All ArcGIS Data Appliance maps use the Web Mercator Auxiliary Sphere tiling scheme (WKID 102100), which is the same tiling scheme that ArcGIS Online, Google Maps, and Bing Maps use. All ArcGIS Data Appliance maps use the same coordinate system, map DPI, and tile size.
What is a WKID?
The Well-Known ID (WKID) is a unique number assigned to a coordinate system. You can find the WKID in the Coordinate Systems Details window. Once you know this number, it’s a handy way to search for the coordinate system later.
What does WKID stand for?
Well-known ID
WKID stands for ‘Well-known ID’ for the object definition.
Which is version of ArcGIS Server does WKID support?
You have not stated what version of ArcGIS Server you are running. If you are on 9.3.1 your stuck with the WKIDs that REST supports: The other option (which I have done before) is submit a WKID request to Esri Support. For me, we sent them the projection file and they created a NIM, and at the next version it was included.
Are there any well known IDs for ArcGIS Server?
Before ArcGIS Server 10.0, the ArcGIS Server REST API only supported well-known IDs (not definition strings), but as of ArcGIS Server 10.0 both are supported. For a complete list of supported well-known IDs and their corresponding definition strings, see links below. Geographic Co-ordinates Systems Listing
How are coordinate systems defined in ArcGIS Server?
Each coordinate system is defined by a well-known ID (WKID) or a definition string (WKT, Well Known Text). Before ArcGIS Server 10.0, the ArcGIS Server REST API only supported well-known IDs (not definition strings), but as of ArcGIS Server 10.0 both are supported.
Do you use WKID or WKT for mapping?
So for mapping, you will have to do it for yourself. make property file, in which you can have the mapping. with complete, WKT. and whenever you need to pass CRS to the ESRI API, always pass the WKT, not WKID. Because There are chances, that wkid is not uderstood within ESRI API, but, internally, ESRI API, can understand the WKT.
