asemapohjaisen

Asemapohjainen is a Finnish adjective used to describe something that is based on a base map (asemapohja) as its underlying reference layer. The most common noun phrases are asemapohjainen kartta or asemapohjainen aineisto, meaning base-map-based map or base-map-based data. The inflected form asemapohjaisen is used when the adjective modifies a noun in certain grammatical cases, for example asemapohjaisen kartan (the base-map-based map) or asemapohjaisen datan (of base-map-based data). In GIS, cartography and geospatial workflows, the term signals that the base map provides the primary geographic frame for subsequent layers, analyses and visualizations.

Context and usage: In Finnish technical writing, asemapohjainen describes approaches and products anchored to a common base map. It is often contrasted with street- or satellite-only approaches, or with framework baselines that do not rely on a single base map. The concept emphasizes consistency across datasets, coordinate systems, and styling, by reusing a shared base map as reference. Example phrases: asemapohjaisen karttakerroksen luominen, asemapohjaisen datan hallinta, or reititys asemapohjaisella karttapohjalla.

Etymology and grammar: The word is built from asemapohja (base map) and the adjectival suffix -inen, yielding asemapohjainen. The related inflected form asemapohjaisen occurs according to Finnish adjective declension rules. The term is primarily used in Finnish GIS literature and Finnish-language geoinformatics discussions.
