During 1990, Statistics Sweden manually delineated all Swedish settlements with at least 200 inhabitants using digital boundaries, housing coordinates, aerial photos, and other sources. The dataset includes an ArcInfo polygon coverage representing these settlement areas, each associated with a name. Projection details are provided using the Transverse Mercator system with a Bessels ellipsoid.
Use Cases
- Map settlement boundaries based on the manually delineated polygon coverage.
- Analyze settlement distribution relative to population thresholds based on the 200 inhabitant criterion.
- Study urban development patterns using the integrated data from housing coordinates, aerial photos, and real estate registers.
Strengths
- Settlement delineation performed by the official national statistics agency, Statistics Sweden.
- Data integration from multiple authoritative sources including digital boundaries, housing coordinates, aerial photos, and a real estate taxation register.
- Projection parameters are explicitly defined, including ellipsoid semi-major and semi-minor axes.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last update date is unknown; freshness unverified.
- Row count is unknown, which may limit suitability assessment.
