Preface

This document establishes the OGC CRS ontology and its submodules. The definition of elements of coordinate reference systems is an essential part of geospatial data provision. However, until now, coordinate reference systems and their components could not be represented in an OGC-standardized semantic web vocabulary. This document introduces the ontology model, its classes and properties, application examples and can serve as the foundation of a semantic web based coordinate system registry at OGC. Special attention is given to the compatibility of the CRS Ontology vocabulary to other OGC-endorsed Semantic Web standards such as GeoSPARQL and alignments to other data standards are provided as part of this specification.

Note

Insert Preface Text here. Give OGC specific commentary: describe the technical content, reason for document, history of the document and precursors, and plans for future work.

There are two ways to specify the Preface: "simple clause" or "full clasuse"

If the Preface does not contain subclauses, it is considered a simple preface clause. This one is entered as text after the .Preface label and must be placed between the AsciiDoc document attributes and the first AsciiDoc section title. It should not be give a section title of its own.

If the Preface contains subclauses, it needs to be encoded as a full preface clause. This one is recognized as a full Metanorma AsciiDoc section with te title "Preface", i.e. == Preface. (Simple preface content can also be encoded like full preface.)

Core

This clause establishes the Core Requirements class, with IRI /req/core, which has a corresponding Conformance Class, Core, with IRI /conf/core.

The Core module establishes a set of classes and properties which define the building blocks of a spatial reference system definition. Some of the definitions are extended in specialized modules related to the Core module.

core

From a base class SpatialReferenceSystem, we define a class for a coordinate system, as the superclass of all spatial reference systems describing locations using coorindates. These SpatialReferenceSystems are described using a Datum and a coordinate system definitions with at least one coordinate axis. Together with several subtypes of coordnate reference system, these definitions complete the Core module.

Projections Module

This clause establishes the PROJ Requirements class, with IRI /req/proj, which has a corresponding Conformance Class, PROJ, with IRI /conf/proj.

projection

A map projection is a specific set of transformations which are used to represent the two-dimensional surface of a globe on a map plane. All map projections are therefore specific coordinate transformations in the sense of the coordinate operation module.

This module does not describe the specific parameters of a map projection because many variants of a map projection with different parameter usage might exist.

Rather we describe the classes to specify the type of projection. Parameter values of the projection type will have to be initialized when instances of the projection class are created.

Appendix E: JSON-LD Context

We provide JSON-LD contexts to be compatible with other JSON-based formats which provide coordinate reference system data.

Overview

Compatibility to PROJJSON

PROJSON is an established format to share geospatial data which has emerge from the PROJ library and encodes the WKT encoding of coordiante references systems. By adding a JSON-LD context to the PROJJSON standard we achieve an immediate compatibility with an established standard simply by extending it by one simple statement.

{
    "@context": "https://opengeospatial.github.io/ontology-crs/context/geosrs-context.json",
    "$schema": "https://proj.org/schemas/v0.7/projjson.schema.json",
    ...
}

We provide examples of application of this JSON-LD context with the distribution of this standard.

Compatibility to OGCJSON

The OGC CRS working group is aiming towards the creation of their own JSON format for CRS. The JSON-LD context we provide aims to be compatible with both PROJJSON and OGCJSON.
