katunimistöpohja

Katunimistöpohja is a Finnish term that translates to "street name base" or "street nomenclature base." It refers to a foundational dataset or registry that contains official street names within a specific geographical area, typically a municipality or a region. This base data is crucial for various administrative, mapping, and navigational purposes.

The primary function of a katunimistöpohja is to provide a standardized and authoritative list of all recognized street names. This includes information such as the official name of the street, its type (e.g., street, avenue, road, lane), and often its corresponding geographical boundaries or cadastral information. Maintaining an accurate katunimistöpohja is essential for services like postal delivery, emergency response, public transportation, and urban planning.

Municipalities are typically responsible for creating and maintaining their own katunimistöpohja. This involves a formal process for proposing, approving, and recording new street names, as well as updating existing ones. Changes can occur due to new developments, renaming of streets for historical or administrative reasons, or corrections to errors. The data is often made available to other government agencies, private companies (such as mapping services and navigation providers), and the public.

In essence, a katunimistöpohja serves as the authoritative source for street naming conventions, ensuring consistency and clarity in addressing and spatial referencing. It underpins the accurate representation of urban environments and facilitates the functioning of many essential services that rely on precise location information.
