1.nounB1
Definition

the work of creating a visual representation of land, showing its physical features like roads, rivers, and hills

Example

Élise spent two summers working on the mapping of the Sahara desert.

mapping + of + [geographical area]

Modern mapping relies on satellite images rather than ground surveys.

adjective + mapping for method type

Common collocations
  • aerial mapping
  • satellite mapping
  • field mapping
  • detailed mapping
  • mapping data
  • mapping project
  • mapping software
Synonyms
  • cartography

    a more formal term for the art and science of map-making; less common in everyday speech

  • surveying

    more specific — refers to measuring and recording land features, not necessarily producing a final map

  • charting

    typically used for sea or sky maps rather than land areas

Grammar Patterns

mapping + of + [geographical area]

Usage Note

Often used as a modifier before another noun, as in 'mapping data' or 'mapping project'.

2. the process of turning information or numbers into a visual form such as a chart

2.nounB2
Definition

the process of turning information or numbers into a visual form such as a chart, diagram, or picture to make patterns easier to see

Example

Iris used colour-coded mapping to show crime rates across different city districts.

adjective + mapping: colour-coded mapping

The mapping of customer complaints revealed that most issues came from late deliveries.

Common collocations
  • data mapping
  • customer mapping
  • colour-coded mapping
  • mind mapping
  • process mapping
  • mapping tool
  • mapping software
Synonyms
  • charting

    more specific — often refers to putting data into a graph format rather than any visual form

  • visualisation

    broader in scope — can include animations and interactive displays, not just static diagrams

  • plotting

    more technical — suggests placing precise points on a coordinate system

Grammar Patterns

mapping + of + [data/information]

Common Mistakes

The mapping diagram shows the data
The mapping shows the data
'mapping' itself already implies a diagram or visual representation; adding 'diagram' is redundant.

3. the scientific process of finding the exact positions of particular genes along

3.nounC1
Definition

the scientific process of finding the exact positions of particular genes along a chromosome

Example

Gene mapping helped scientists identify the DNA sequence responsible for cystic fibrosis.

compound noun: gene mapping

Ziad's research team published a comprehensive mapping of the genes on chromosome 12.

mapping + of + [chromosome]

Common collocations
  • gene mapping
  • genome mapping
  • chromosome mapping
  • genetic mapping
  • DNA mapping
  • mapping data
  • mapping technique
Synonyms
  • genome mapping

    broader — refers to mapping an entire genome rather than individual genes

  • sequencing

    different process — sequencing determines the order of DNA building blocks, not their chromosomal positions

Grammar Patterns

gene mapping

mapping + of + [chromosome/genome]

Usage Note

Frequently encountered in the compound form 'gene mapping'. Distinguished from sense 4 in that this sense refers to physical locations on a chromosome, not locations in the brain.

4. the scientific process of discovering which parts of the brain are responsible f

4.nounC1
Definition

the scientific process of discovering which parts of the brain are responsible for particular abilities or actions

Example

Brain mapping studies showed that the same region handles both speech and singing.

compound noun: brain mapping

Researchers used fMRI for the mapping of memory functions in older adults.

mapping + of + [cognitive function]

Common collocations
  • brain mapping
  • neural mapping
  • cortical mapping
  • functional mapping
  • mapping study
  • mapping technique
Synonyms
  • neural mapping

    slightly broader — can refer to mapping nerve connections anywhere in the body, not just the brain

  • cortical mapping

    more specific — refers only to the cerebral cortex, not deeper brain structures

Grammar Patterns

brain mapping

mapping + of + [brain region]

Usage Note

Frequently encountered in the compound 'brain mapping'. The tool most commonly associated with this process is fMRI (functional magnetic resonance imaging).

5.nounC1
Definition

in mathematics, a rule that pairs each element of one group with exactly one element of another group

Example

In algebra, a linear mapping sends straight lines to straight lines.

adjective + mapping: linear mapping

The mapping f(x) = x² connects each real number to its square.

mapping expressed as f(x) notation

Common collocations
  • linear mapping
  • continuous mapping
  • one-to-one mapping
  • bijective mapping
  • inverse mapping
  • identity mapping
  • mapping function
Synonyms
  • function

    more common in school mathematics and basic calculations; 'mapping' is more common in advanced and abstract maths

  • transformation

    suggests the output set is the same as the input set (e.g., mapping a shape to a new position)

  • operator

    typically used when the mapping acts on functions rather than numbers

Grammar Patterns

[adjective] mapping

mapping + between + [set] + and + [set]

Usage Note

Also called a 'function'. In pure mathematics, 'mapping' and 'function' are often used interchangeably, though 'mapping' may emphasise the idea of linking one set to another.

Common Mistakes

The mapping from A to B is one-to-one, meaning each element in B connects to exactly one element in A.
The mapping from A to B is one-to-one, meaning each element in A connects to a unique element in B.
In a one-to-one mapping, different inputs must give different outputs; the confusion is about which direction the uniqueness applies.

Synonym discussion

Sense: noun/1

All three words relate to representing physical spaces, but they differ in scope and method. Cartography is the broadest and most formal term — it covers the art, science, and technology of making maps, from design to production. Surveying is the practical fieldwork of measuring distances, angles, and elevations on the ground; you do survey work before you can produce a map, but surveying does not itself produce the final map. Charting overlaps with mapping but is traditionally used for navigation — charting a sea route or plotting the stars. In everyday usage, mapping is the most general word and can replace any of the others. If you are describing the physical act of measuring land, use surveying. If you mean the full design process of a printed or digital map, cartography sounds more professional.

Etymology

LatinFrenchEnglish

The noun 'mapping' comes from the verb 'to map', which first appeared in English in the 1500s. 'Map' itself traces back through Latin 'mappa' (meaning 'napkin' or 'cloth'), because early maps were often drawn on pieces of cloth. The phrase 'mappa mundi' — 'cloth of the world' — was used in medieval Latin for a world map. By the 1800s, 'mapping' had moved beyond geography into mathematics to describe functions that pair elements of one set with another. In the 1900s, the term expanded further into genetics (locating genes) and neuroscience (identifying brain regions), following the metaphor of plotting positions on a chart.
