Greenland imagery and land cover data

satellite imagery by Cave Exploration and Research Initiative, acquired 2025-03-30 to 2025-03-31, 3.1 cm per pixel, published on OpenAerialMap.

EOxCloudless is a global satellite imagery dataset consisting of near-cloudless mosaics derived from Copernicus Sentinel-2 multispectral satellite data. The dataset is produced by EOX IT Services GmbH and is designed to provide consistent, high-resolution surface imagery for mapping, analysis, and visualization purposes. The mosaics are generated by combining a large number of Sentinel-2 Level-1C observations acquired over defined time periods. Advanced pixel selection algorithms and thematic masks (including clouds, cloud shadows, and water) are applied to reduce cloud contamination. For each pixel location, the most representative observation is selected based on statistical criteria and temporal analysis, resulting in near-cloudless composite images. The dataset provides global land coverage and is typically delivered at a spatial resolution of 10 metres for the utilised spectral bands (blue, green, red, and near-infrared). EOxCloudless is suitable for use as a basemap as well as for environmental monitoring, land analysis, spatial planning, and other geoscientific applications. Official metadata Purpose The dataset has been adapted and created specifically for display on the Greenland Portal. Lineage EOX Sentinel-2 cloudless is a purchased dataset from the company EOX that contains a mosaic of cloudless satellite imagery worldwide on a scale of 1:20.000. The original dataset consists of a GeoPackage with tiles of 512 x 512 pixels with LZW (lossless) compression where the individual tiles are stored as GeoTIFFs with 8-bit RGB bands, each in a non-projected geographical coordinate system (WGS 84, EPSG: 4326). The data set is cut to Greenland only and projected from WGS 84 to projected coordinate system WGS 84 / UTM 24N (EPSG: 32624).
