Karttoissa

Karttoissa is the inessive plural form of the Finnish noun kartta, meaning map. It expresses location within multiple maps, roughly translating to “in/on the maps.” The form is a grammatical construction rather than a separate concept, and it is used when describing information that appears across several maps or content that applies to maps collectively.

Morphology and usage

The base word is kartta (map). The plural nominative is kartat. To form the plural locative, Finnish adds the inessive plural suffix -issa, yielding karttoissa. This construction indicates that something is located inside or represented on several maps rather than on a single map.

Examples

- Nimet ja rajat näkyvät karttoissa. (Names and borders appear on the maps.)

- Tutkimuksessa esitetään tiedot karttoissa. (The data are presented in the maps.)

- Kuvamerkinnät voidaan tarkistaa karttoissa. (The symbols can be checked on the maps.)

Distinctions

The singular counterpart is kartassa, meaning “in/on the map.” Karttoissa thus contrasts with kartassa by referring to multiple maps rather than a single map. In geographic information systems (GIS) and technical contexts, more specific terms may be used (such as tietty karttataso or karttakerros) depending on the software or data model.

Overview

Karttoissa is primarily a grammatical form used in Finnish writing and speech to discuss content that spans several maps. It is not a separate field or concept in geography, but a common way to reference information found within multiple maps. See also: kartta, kartat, inessive case.
