CRS

specstableimplmature

Additional coordinate reference systems.

Scope

The building block CRS provides support for additional coordinate reference systems apart from the default CRS84open in new window (WGS 84).

All transformations between two coordinate reference systems are handled by PROJ. If multiple transformations are available, PROJ decides which one to use.

Conformance Classes

CRS implements all requirements of conformance class Coordinate Reference System by Reference of OGC API - Features - Part 2: Coordinate Reference System by * Reference 1.0.1open in new window.

Query Parameters

NameResourcesDescription
crs
Features, Feature
The coordinate reference system of the returned features. Default is WGS84 longitude/latitude (with or without ellipsoidal height).
bbox-crs
Features
The coordinate reference system of the bbox parameter. Default is WGS84 longitude/latitude.

Configuration

NameDefaultDescriptionTypeSince
buildingBlock
Always CRS.
string

boolean

additionalCrs
{}
Lists additional coordinate reference systems to be supported in the API or for a feature collection. The native coordinate reference system of the data and the default coordinate reference system of the API are automatically enabled. Coordinate reference systems are identified by their EPSG code (code). Additionally, the order of the coordinate axes must be specified in forceAxisOrder (NONE: as in the coordinate reference system, LON_LAT or LAT_LON: the order in the coordinate reference system is ignored and the specified order is used).
array
v2.0
suppressGlobalCrsList
false
If true, the coordinate reference systems will be included in every Collection resource that is embedded in the Collections resource. The global crs array will not be used or referenced. Use this option, if the API is intended to be used with a client that does not support the global crs array.
boolean
v2.0
