The main goals of the Spatial Reference Catalog service are to offer:
- Coordinate Reference Systems (CRSs) to enable end users to make a CRS selection.
- Search for CRSs given a number of constraints.
- Download of the entire catalog for local caching and when the cache has to be refreshed.
- Access to various subsets of the catalog.
- After a CRS is found, produce a persistable reference to be stored with the data, which fully describes the CRS. This persistable reference string becomes catalog independent. This means any consumer will be able to understand the CRS definition even if a different catalog is used in the future context.
Coordinate Reference Systems (CRS) consists of a coordinate system combined with a geodetic reference. The geodetic reference, also called a geodetic datum or geographic coordinate reference, system takes an ellipsoid as a mathematical approximation of the earth and a prime meridian where the longitude is zero. The latitude is zero at the equator. The latitude and longitude are measured in plane angles (spherical coordinate system). Because the mathematical shape is an approximation, there are many realizations of geodetic references, often optimized for a single landmass or continent. Some examples include NAD27, NAD83 in North America, and ED50 in Europe.
With the introduction of satellites, a one world-wide approximation has been defined, which is the World Geodetic System of 1984 (WGS 84). This is the reference used in the Global Positioning System. WGS 84 is still a mathematical approximation. Over time, plate tectonics move the continents under the ellipsoid. At the moment, the relative shifts are in the order of normal GPS resolution, but it will accumulate further over time. Eventually the geospatial references will become time dependent. The current catalog does not contain any time-dependent elements yet.
Each geodetic reference is independent. One physical position will manifest itself with different numeric coordinate values based on different geodetic references. The operation to perform a datum transformation is called a cartographic transformation (CT). The CRS catalog contains a list of such transformations. Often there are many realizations of transformations for a given pair of geodetic datums. The choice of transformation is non-trivial and typically the responsibility of geodesists or geomatics specialists. Ordinary end users or data consumers are not able to make such decisions.
This is the reason why so-called early-bound coordinate reference systems (EarlyBoundCRS) were introduced. An early-bound CRS pairs a (late-bound or un-bound) LateBoundCRS with a unique cartographic transformation CT. Typically this transformation links the CRS's geodetic reference to WGS 84. Different early-bound CRSs then enable the any datum to any datum case, using the hub CRS WGS 84. Generally, only EarlyBoundCRSs are of any practical use to applications because of their versatility to be converted to any other EarlyBoundCRS. Only a LateBoundCRS based on WGS 84 can deliver the same versatility. For simplicity, all CRS types have a transformationReady property. If this property is true, then data can likely be converted to any other geodetic reference.
Finally, there are map projections based on geographic CRSs, so-called projected CRSs. Projected CRSs use a Cartesian coordinate system, meaning that both axes are measured in length. All projected CRSs are initially defined as late-bound or un-bound CRSs. When such a CRS is bound to a cartographic transformation, a projected, early-bound CRS is created.
So far we only covered 2D CRSs, meaning the third dimension is implicitly given as height above mean sea level (MSL). Almost all CRSs currently in use are 2D CRSs. Currently, transformations between 2D CRSs do not change the vertical values (z-coordinate) because the values refer implicitly to the same MSL reference surface.
Eventually more formal 3D CRSs will be introduced, CompoundCRS. Such CRSs combine a horizontal CRS (a conventional 2D CRS) with a 1D vertical CRS. Both CRSs can be early-bound, meaning they are associated to a transformation to WGS 84 (2D) or associated to a transformation to MSL (1D). The CRS catalog contains a few examples of WGS 84 based UTM projections (2D) paired with the EGM96 height CRS (1D). These CRSs are 'demonstrators' for the concept but currently not supported by the coordinate conversion service.
Here are more notes about cartographic transformations. There are two types of transformations:
SingleCT,a single transformation, the most common type.CompoundCT,which consists of manySingleCTitems with apolicyof how to use them.- The
policy'fallback' means that the list of transformations is tried one by one until a point is successfully transformed. - The
policy'concatenated' means that the points are sequentially transformed, such as T1->T2->T3.
- The
Finally, to aid the selection process, CRS and CT can be associated with AreaOfUse definitions, which provide a simple bounding box in WGS 84 latitude and longitude. The CRS catalog offers a list of such definitions.
Overview of types delivered by the CRS Catalog:
| Item type | Link to item details |
|---|---|
LateBoundCRS | Late-bound or un-bound CRS details |
EarlyBoundCRS | Early-bound CRS details |
CompoundCRS | Compound CRS details |
SingleCT | Single CT details |
CompoundCT | Compound CT details |
AreaOfUse | Area of use details |
The following sections elaborate a few use cases.
Find all CRSs in a given area, which are data CRS candidates. A coordinate reference system is often not enough to enable flexible coordinate conversion/transformation. To ensure that this is the case, it is possible to require transformation-ready CRSs, meaning CRSs which allow transformations to other geodetic datums.
Optionally, the area of use can be constrained. Decimal values are expected in degrees latitude, longitude referring to the WGS 84 CRS. The four values span a bounding box in spherical coordinates:
Let us run an example with the following constraints:
- Only return CRSs which are bound to a cartographic transformation to WGS 84 or based on WGS 84. This becomes a query constraint.
- Only return CRSs which are based on NAD27, EPSG, or 4267. This becomes a query constraint.
- Longitude range between 100°W and 80°W [-100, -80].
- Latitude range between 20°N and 50°N [20, 50].
- Limit the response to the first two items in the catalog.
- Request that returned data contains the JSON structure of the essence rather than the persistable reference (default).

}When populating a multi-purpose CRS selector, this method offers access to all CRSs of any sub-type as defined in the catalog:
GET /api/v2/crs?offset={offset}&limit={limit}| Parameter | Value |
|---|---|
| {offset} | 0 (default 0) |
| {limit} | 1000 (default 100, -1 for all) |
| {mode} | What kind of response persistable_reference (default), populates namedReference or essence, populates essence property or persistable_and_essence to have both namedReference and essence populated. |
Open Try it out: get-all-crs The response structure is of type CRSResults, which is the same structure as for the search use case above.
CURL get all CRS command
curl --request GET \
--url '{root-url}/api/v2/crs?limit=1000&offset=0&mode=essence' \
--header 'Authorization: Bearer {Java-Web-Token}'In some cases apps may want to cache the entire catalog of coordinate reference systems and cartographic transforms. The CRS catalog service supports this with the following two methods:
/catalogto request the catalog summary. Open Try it out in a new window. The response is of type Catalog./catalog/attributesto request the last modification date of the catalog. Open Try it out in a new window. The response if of type CatalogAttributes.
The latter method allows apps to determine when the cached contents has become stale and needs a refresh.
