National Map Library

National Map Library 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 National Map Library rather than just read about it. In short: The National Map Library (Greek: Εθνική Χαρτοθήκη), properly the National Centre for Maps and Cartographic Heritage - National Map Library, is located in Thessaloniki, Central Macedonia, Greece. It was established in 1997 (Law 2466/1997) for the purpose of preserving, archiving, conserving, promoting, and displaying maps, studying the educational, cultural, and social role of maps, collaborating at a scientific and…

Key takeaways

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

Reference excerpt

The National Map Library (Greek: Εθνική Χαρτοθήκη), properly the National Centre for Maps and Cartographic Heritage - National Map Library, is located in Thessaloniki, Central Macedonia, Greece. It was established in 1997 (Law 2466/1997) for the purpose of preserving, archiving, conserving, promoting, and displaying maps, studying the educational, cultural, and social role of maps, collaborating at a scientific and technical level with national and international organizations, organizing permanent and mobile exhibitions accompanied by catalogues, utilising public and private map collections, and organising seminars and conferences. Since February 1999, the National Map Library has been housed in a two-storey listed building in the Upper Town (Ano Poli). On the ground floor are the scientific and administrative departments and on the first floor there is a permanent exhibition space which hosts frequent cartographic exhibitions. There is an archive of 1,000 maps, which are being electronically documented and archived with the help of a special database. Between 1 and 12 November 1999, there was an exhibition of six 19th-century cartoon maps of Europe, five children's maps which had been entered for the international cartographic competition in 1999, and some rare maps drawn by Sotiris Zissis, a self-taught Thessalonian cartographer. Other exhibitions organised by the National Map Library include History in Maps at the Residency, Maps of Ports of Greek Cities of the Twentieth Century in the National Research Institute, and Greek Cartography in Thessaloniki in the Twentieth Century. An educational programme titled The National Map Library Meets Teachers and Children has been drawn up and is addressed to schools in Macedonia and Thrace.

Worked examples

Example 1 — a first encounter with National Map Library

Start with the simplest possible case. Write down what National Map Library 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 National Map Library 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 National Map Library 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 National Map Library

In research: National Map Library 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 National Map Library 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: National Map Library is common in secondary-school and first-year university syllabi. It links to neighbouring topics Libraries established in 1997, Libraries in Greece, Map collections, so understanding it makes those chapters shorter.
In everyday life: Look for National Map Library 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.
