kerrostamistiedot

Kerrostamistiedot on termi used in Finnish urban planning to describe information related to densification and multi-storey construction in cities. It covers data about where additional storeys or new apartment buildings may be planned, as well as the regulatory framework that governs such developments. The concept centers on the rights and constraints attached to building in a given area and how these affect the density and form of urban housing.

The data typically includes zoning plans (asemakaava and yleiskaava), the permitted building rights (rakennusoikeus), and the related limits on height and number of storeys. It also encompasses current and proposed plans for specific plots, density indicators, and information about infrastructure or street- and plot-level restrictions that influence kerrostamista.

Uses of kerrostamistiedot span planning, research, and public information. City planners and developers rely on the data to assess where densification is possible or desirable, to perform geographic information system (GIS) analyses, and to model housing supply and neighborhood change. Residents, journalists, and researchers can use it to understand how and where a city may grow vertically.

Access to kerrostamistiedot is usually through municipal planning portals and national open-data platforms. Datasets are commonly provided as maps and files in GIS formats such as shapefiles or GeoJSON, and may also exist as tabular data. Availability and update frequency vary by jurisdiction and dataset, reflecting planning processes rather than guaranteed construction.

Limitations include that the data represents plans and rights, not guaranteed development or actual construction. Legal status depends on permits, approvals, and subsequent changes in the planning framework.
