Mapped

Mapped is the past participle of map and an adjective used across fields to indicate that something has been represented, assigned, or converted according to a mapping process. As a verb form, it appears in phrases such as “the data were mapped” or “the features are mapped to coordinates.”

In cartography and geography, mapped data are transferred to geographic coordinates or projected onto a map. Features on a dataset can be described as mapped to a region, ensuring their locations and attributes align with a chosen coordinate system or projection.

In computer science, mapped has several common uses. The map function applies a given operation to each element of a collection, producing a new, mapped collection. Memory-mapped I/O and memory-mapped files refer to techniques that map files or devices into a program’s address space, enabling direct access. Mapping also describes the association between keys and values in data structures such as maps or dictionaries, and the concept of mapped types in some programming languages involves transforming or inferring new types from existing ones.

In genetics, genetic mapping refers to determining the location of genes on chromosomes, effectively mapping traits to chromosomal regions. The term can also appear in other disciplines where a correspondence or transformation between sets is established, such as mapping semantic or functional relationships between concepts.

Overall, “mapped” conveys that a relationship, transformation, or representation has been established between elements, spaces, or data, typically as part of a systematic process.
