World Map 1:2,500,000

World Map 1:2,500,000 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 World Map 1:2,500,000 rather than just read about it. In short: The World Map 1:2,500,000 (Russian: Карта Мира 1:2,500,000) is an internationally standardized and edited map series. The Russian term Карта Мира or in transcription Karta Mira is now commonly used to describe this series, even outside the Soviet Union or Russia.

Key takeaways

  • World Map 1:2,500,000 belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect World Map 1:2,500,000 to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of World Map 1:2,500,000 from memory before moving on to harder problems.

Reference excerpt

The World Map 1:2,500,000 (Russian: Карта Мира 1:2,500,000) is an internationally standardized and edited map series. The Russian term Карта Мира or in transcription Karta Mira is now commonly used to describe this series, even outside the Soviet Union or Russia. The Karta Mira consists of a total of 224 (#1–17 & 28–234) main sheets and 38 overlap sheets (although at least 10 were dropped). They depict the entire earth (land and water surfaces) according to a uniform scale, coloring and drawing system. The Karta Mira 1956–1975 was produced by cartographers from Bulgaria, Czechoslovakia, the German Democratic Republic (GDR), Hungary, Poland, Romania and the Soviet Union. The production of a 1:2,500,000 scale map of the world had been discussed since the late 1940s, partly because many cartographers were dissatisfied with the work on the International Map of the World (or Millionth Map, after its scale of 1:1,000,000). Due to the destruction of the Central Bureau of the Map of the World in London during World War II, the Millionth Map had suffered a serious setback, and it was uncertain whether that series could ever be completed. The initiative for the production of the Karta Mira was taken by cartographers from Hungary (Alexander Radó, Peter Halasz, E. Foldi, Istvan Joo), the Soviet Union (Grigory A. Ginzburg (Григорий А. Гинзбург), Ilya Andreyevich Kutuzov (Илья Андреевич Кутузов)) and the GDR (Erfried Haack, Horst Nischan, Manfred Pateisat). Production of the 262 sheets was divided between the geodetic services of the participating countries. Thus, the sheets to be produced in the GDR were printed by VEB Hermann Haack Geographisch-Kartographische Anstalt Gotha and VEB Kombinat Geodäsie und Kartographie in Leipzig and Potsdam. The sheets to be produced in the Soviet Union were created by the Department of Geodesy and Cartography (Главное управление геодезии и картографии) in Moscow. Proofs of several of the sheets involved in the series were presented by East German cartographers at an international conference in Erfurt in December 1963. The first four sheets were published in 1964, and the final sheets of the first edition in 1976. Sheets were published in several versions: a full version, a version without contours (for social science thematic mapping) and a version without placenames and infrastructure (for scientific thematic mapping). The title of each sheet was given in Cyrillic and Latin alphabets, but all placenames on the map itself were given only in the Latin alphabet. Publication of a second edition began in 1989, but appears to have been abandoned with the collapse of the Communist regimes in the Eastern Bloc shortly thereafter.

Worked examples

Example 1 — a first encounter with World Map 1:2,500,000

Start with the simplest possible case. Write down what World Map 1:2,500,000 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 World Map 1:2,500,000 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 World Map 1:2,500,000 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 World Map 1:2,500,000

In research
World Map 1:2,500,000 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 World Map 1:2,500,000 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
World Map 1:2,500,000 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Map series, World maps, so understanding it makes those chapters shorter.
In everyday life
Look for World Map 1:2,500,000 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.
