peruskartta

Peruskartta is a Finnish term referring to a fundamental or basic map. In a cartographic context, it signifies a topographic map that serves as a foundational representation of an area's geographical features. These maps typically depict natural elements such as elevation contours, bodies of water, and vegetation, as well as man-made structures like roads, buildings, and administrative boundaries.

The purpose of a peruskartta is to provide a comprehensive and detailed overview of the landscape, making it suitable for a wide range of applications. This includes land-use planning, environmental studies, surveying, and recreational activities such as hiking and orienteering. They are often produced at a relatively large scale, allowing for the depiction of significant detail.

In Finland, the National Land Survey of Finland (Maanmittauslaitos) is responsible for the production and maintenance of official topographic maps, which can be considered peruskartta in their function. These maps are crucial for understanding and managing the Finnish terrain and its diverse features. The term emphasizes the essential and foundational nature of these maps in any geographical information system or planning process.
