Land Mask & Standard Resolutions
For consistency, OGCR uses a single pan-EU land mask — prepared by the AI4SoilHealth project and available at 10.5281/zenodo.8171860. Three companion masks are provided for different production workflows:
- Land mask — values differentiating land, ocean and inland water;
- NUT-3 code map — NUTS-3 administrative areas;
- ISO-3166 country map — countries per the ISO-3166 standard.
The pan-EU land mask is derived from the highest-quality geospatial sources, including the CCL+ Backbone, WorldCover (10 m) and the JRC Global Surface Water (30 m). The notebooks and scripts used to produce masks, merge tiles, reproject and resample are available on Zenodo.
Land mask updates
Because most downstream predictions depend on the land mask, updates are typically needed only on a 2–5 year cycle.
Pan-EU definition
OGCR targets pan-EU, defined here as:
- EU (excluding Caribbean islands, Réunion, etc.) / European Economic Area + UK + Norway + Switzerland;
- Western Balkans (Bosnia & Herzegovina, Serbia, Kosovo, Albania, Moldova);
- Candidate countries — Turkey and Ukraine.
The land mask need not include every country above, but must cover a complete land mask for the EU member states.
Standard bounding box & resolutions
For compatibility, project participants exchange data at standard pixel sizes within the EU01 bounding box (EPSG:3035):
| Europe COG bounding box (EPSG:3035) | Spatial resolutions & image size (EPSG:3035) |
|---|---|
| Xmin = 900,000 · Ymin = 930,010 · Xmax = 6,540,000 · Ymax = 5,460,010 | 10 m: 564,000 × 456,000 · 30 m: 188,000 × 151,000 · 100 m: 56,400 × 45,600 · 250 m: 22,560 × 18,240 · 1 km: 5,640 × 4,560 |
Other bounding-box codes in use:
- EC01 — EU countries (without Caribbean islands, Réunion, etc.);
- EEA01 — European Economic Area + UK + Norway + Switzerland (without Caribbean islands, Réunion, etc.).
