ISO 19114

ISO 19114 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 ISO 19114 rather than just read about it. In short: ISO 19114 Geographic information - Quality evaluation procedures provides a procedural framework for evaluating the quality of digital geographic datasets, consistent with the data quality principles defined in ISO 19113. It consists of three classes of conformance: one for quality evaluation, one for evaluating data quality and on for reporting quality information.

Key takeaways

  • ISO 19114 belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect ISO 19114 to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of ISO 19114 from memory before moving on to harder problems.

Reference excerpt

ISO 19114 Geographic information - Quality evaluation procedures provides a procedural framework for evaluating the quality of digital geographic datasets, consistent with the data quality principles defined in ISO 19113. It consists of three classes of conformance: one for quality evaluation, one for evaluating data quality and on for reporting quality information. It is an international standard developed by the International Organization for Standardization. This standard has been withdrawn and been revised by ISO 19157.

Worked examples

Example 1 — a first encounter with ISO 19114

Start with the simplest possible case. Write down what ISO 19114 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 ISO 19114 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 ISO 19114 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 ISO 19114

In research
ISO 19114 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 ISO 19114 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
ISO 19114 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Geographic information systems, ISO standards, Standards and measurement stubs, so understanding it makes those chapters shorter.
In everyday life
Look for ISO 19114 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 ISO 19114 in simple terms?

ISO 19114 Geographic information - Quality evaluation procedures provides a procedural framework for evaluating the quality of digital geographic datasets, consistent with the data quality principles defined in ISO 19113. It consists of three classes of conformance: one for quality evaluation, one…

Why does ISO 19114 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 ISO 19114?

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.
