Kartoittanut

Kartoittanut is the past active participle of the Finnish verb kartoittaa, which means to map, chart or survey. The form indicates that the subject has carried out mapping. In Finnish, kartoittanut is used with auxiliary verbs to form perfect tenses, for example Hän on kartoittanut alueen. As a participle it can also function descriptively in larger sentences, though the adjectival sense is more commonly expressed with the passive kartoitettu.

Fields such as geology, archaeology, urban planning and environmental science frequently rely on mapping. Kartoittaminen and kartoitus refer to the process of gathering spatial data, creating maps, inventories of resources, topography, land use and hazards. The past active participle kartoittanut appears in narrative or formal writing to indicate completed mapping by a subject.

Etymology and related terms: The word is formed from kartoittaa with the past active participle suffix -nut (-nyt after a vowel). Related terms include kartoitus (the act of mapping) and kartoittaminen (the process of mapping). It is distinct from the passive form kartoitettu, which denotes that something has been mapped by someone or by authorities.
