GeoIndex Landsat Imagery: UK Satellite Mosaic 1984-1990

Landsat Thematic Mapper satellite imagery of the United Kingdom, acquired between 1984 and 1990, forms this processed geospatial mosaic. The data is presented at a native 30-meter resolution and has been contrast-enhanced by the BGS Remote Sensing Section to highlight geological and geomorphic features. Winter imagery with infrared wavelengths was selected to accentuate landscape topography under low sun angles.

Use Cases

• Geological mapping based on processed infrared bands that enhance natural boundaries.
• Geomorphic feature interpretation based on winter imagery with low sun angles.
• Historical land cover analysis for the UK based on 1984-1990 satellite data.
• Creating basemaps for environmental studies based on a country-wide satellite mosaic.

Strengths

• Covers a significant time range, with imagery acquired between 1984 and 1990.
• Offers high spatial detail with a native resolution of 30 meters per pixel.
• Includes processed infrared wavelengths specifically chosen to extract geological information.

Limitations

• Metadata is incomplete, with no information on license, author, or exact data size.
• The mosaic is composed of images from different dates and conditions, leading to visible seams and inconsistencies.
• The data is not recent, with the latest acquisition year being 1990.
