To see a list of supported WKIDs and their WKT definitions for geographic coordinate systems, projected coordinate systems, vertical coordinate systems, and transformations, see Supplemental ArcGIS Data or visit the GitHub repository. Note that for versions prior to ArcGIS 10, only WKID was supported. ProjectedCoordinateSystem); // investigate one of the entries CoordinateSystemListEntry entry = gcs_list[0]; int wkid = entry. Many thanks Jul 12, 2025 · These codes simplify the identification and use of spatial reference systems in various geospatial applications. # Loop through the list for fc in feature_classes: # Create the spatial reference object spatial_ref = arcpy. Table of Contents Table 1: Linear units: well-known IDs and conversion values 1 Each WKID defines the coordinate system with all parameters needed to represent spatial data. Specifically USA Contiguous Lambert Conformal Conic. I swear I saw this on EDN site but can't find this list anywhere. Many predefined spatial references have already been defined and are available for use. Each projected and geographic coordinate system is defined by either a well-known ID (WKID) or a definition string (WKT). spatialReference # If the spatial reference is unknown if spatial_ref. 5 Projected Coordinate System Tables Note: Values may be rounded for display. 1 Projected Coordinate System Tables Note: Values may be rounded for display. GeographicCoordinateSystem | CoordinateSystemFilter. Some common WKIDs are mentioned in the text below; for a more complete description, see Spatial reference specifications in this topic. The default tolerance and resolution ArcGIS 10. Applications use a spatial reference to correctly display geographic data in a map or scene. Instance. Aug 4, 2010 · I'm hoping to find a list of WKID values that corespond to their coordnate system's. Wkid; Each coordinate system is defined by both a well-known ID (WKID) and a definition strings (WKT1 and WKT2). May 2, 2025 · IReadOnlyList<CoordinateSystemListEntry> combined_list = GeometryEngine. The source, origin, or authority of the number is either Esri or the former European Petroleum Survey Group (EPSG). A spatial reference is a set of parameters, typically defined by a WKID, that define the coordinate system and spatial properties for geographic data. A spatial reference can be defined using a well-known ID (WKID) or well-known text (WKT). ArcGIS Pro 3. Spatial references can be referred to by a well-known ID (WKID)—an integer value. For a complete list of supported IDs and their corresponding definition strings, see the following:. In addition to this, it is also available within the operationalLayer and basemap objects. Area of use values are in decimal degrees based upon WGS 1984. name == "Unknown": print(r"{fc} has an unknown spatial reference") # Otherwise, print out the feature class name and spatial reference else: The spatialReference object is located at the top level of the web map JSON hierarchy. Describe(fc). For a full list of supported spatial reference IDs and their corresponding definition strings, see Using spatial references. Find your references in any number of formats!
