Swedish Terrain Classification from Precision-Corrected Satellite Imagery

A digital terrain type database covering all of Sweden, derived from high-resolution satellite imagery. The dataset comprises 900 map sheets, each covering a 25x25 square km area, produced between February 1990 and July 1991 by SSC Satellitbild in Kiruna, Sweden. Information was extracted using computerized multispectral classification and image processing methods.

Use Cases

• Classifying terrain types using multispectral classification data from satellite imagery.
• Analyzing land cover patterns across Sweden at a 25-meter pixel resolution.
• Creating historical baselines for environmental studies using data from 1990-1991.
• Validating geocoding models that account for satellite motion and sensor properties.

Strengths

• Geometrically precision-corrected to the Swedish National Grid with high accuracy.
• Covers all of Sweden across 900 individual map sheets.
• Uses high-resolution satellite imagery resampled to a consistent 25 m pixel-size.

Limitations

• Data is from 1990-1991 and may not reflect current land cover conditions.
• Specific row counts, column names, and file formats are unknown.
• The original satellite imagery source and specific spectral bands used are not detailed.
