OGC Reference Model

OGC Reference Model is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand OGC Reference Model rather than just read about it. In short: The OGC Reference Model describes a framework for the ongoing work of the Open Geospatial Consortium (OGC) and their specifications and implementing interoperable solutions and applications for geospatial services, data, and applications. It is not an OGC standard.

Key takeaways

  • OGC Reference Model belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect OGC Reference Model to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of OGC Reference Model from memory before moving on to harder problems.

Reference excerpt

The OGC Reference Model describes a framework for the ongoing work of the Open Geospatial Consortium (OGC) and their specifications and implementing interoperable solutions and applications for geospatial services, data, and applications. It is not an OGC standard. It has the following purposes:

Provides a foundation for coordination and understanding (both internal and external to OGC) of ongoing OGC activities and the Technical Baseline; Update/Replacement of parts of the 1998 OpenGIS Guide; Describes the OGC requirements baseline for geospatial interoperability; Describes the OGC architecture framework through a series of non-overlapping viewpoints: including existing and future elements; Regularize the development of domain-specific interoperability architectures by providing examples.

External links The full specification is a public document, and can be downloaded from the OGC Web site.

Worked examples

Example 1 — a first encounter with OGC Reference Model

Start with the simplest possible case. Write down what OGC Reference Model claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to OGC Reference Model before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about OGC Reference Model ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of OGC Reference Model

In research
OGC Reference Model appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses OGC Reference Model in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
OGC Reference Model is common in secondary-school and first-year university syllabi. It links to neighbouring topics Geographic information systems, Open Geospatial Consortium, Reference models, so understanding it makes those chapters shorter.
In everyday life
Look for OGC Reference Model outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is OGC Reference Model in simple terms?

The OGC Reference Model describes a framework for the ongoing work of the Open Geospatial Consortium (OGC) and their specifications and implementing interoperable solutions and applications for geospatial services, data, and applications. It is not an OGC standard.

Why does OGC Reference Model matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study OGC Reference Model?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on OGC Reference Model.
