Karttapohjaisia

Karttapohjaisia is a Finnish adjective describing content, tools, or tasks that use a map as their underlying reference layer or base. It denotes that the map functions as the backdrop or frame for presenting information, rather than using non-spatial graphics. The term is common in fields such as geographic information systems (GIS), cartography, education, and digital media to signal a map-driven approach.

The word is formed from kartta (map) and pohja (base) with the suffix -inen, producing karttapohjainen, and its plural partitive form karttapohjaisia is used to modify plural nouns, for example karttapohjaisia tehtäviä (map-based tasks) or karttapohjaisia sovelluksia (map-based applications). The phrase is typically used to distinguish spatially anchored or map-centered content from purely tabular, text, or image-based formats.

In practice, karttapohjaisia products and activities often incorporate a map background with layered geospatial data, interactive features such as panning and zooming, and capabilities for spatial analysis or visualization. Applications include educational exercises that require locating places on a map, assessing geographic patterns, or interpreting thematic layers. The concept is closely related to karttapohja (map background) and to broader notions of map-based design in web mapping, digital atlases, and spatial data visualization.
