The spatialReference object is located at the top level of the JSON hierarchy. A spatial reference can be defined using a Well-Known ID (WKID) or Well-Known Text (WKT). The default tolerance and resolution values for the associated Coordinate Reference System (CRS) are used.
A spatial reference can optionally include a definition for a vertical coordinate system (VCS), which is used to interpret a geometries z values.

| Property | Type | Description |
|---|---|---|
| latestVcsWkid | integer | The current WKID value of the vertical coordinate system. |
| latestWkid | integer | Identifies the current WKID value associated with the same spatial reference. For example a WKID of '102100' (Web Mercator) has a latestWKid of '3857'. |
| vcsWkid | integer | The WKID value of the vertical coordinate system. |
| wkid | integer | WKID, or Well-Known ID, of the CRS. Specify either WKID or WKT of the CRS. |
| wkt | string | WKT, or Well-Known Text, of the CRS. Specify either WKT or WKID of the CRS but not both. |
