Global land cover data set at 10m for 2015 (Geo-Wiki)

This data set was created to support the C-GLOPS (Copernicus Global Land Operational Services) and WorldCover projects during the time period 2017-2022.

Method employed: visual interpretation of very high resolution images and other sources of information using the Geo-Wiki tools.

More than 15 interpreters were involved in the data collection exercise.

Temporal resolution: 2015.

Spatial resolution: 10m x 10m, aligned with Sentinel-2 pixels.

Number of records: 16,569,600.

Thematic resolution:  Bare,  Burnt,  Crops, Fallow land/shifting cultivation, Grassland, Lichen and moss, Not sure, Shrub, Snow and ice, Trees, Urban/built-up, Water, and Wetland (herbaceous).

Fields:

• validation_id - unique annotation id for a cluster of 100 pixels, each 10m x 10m in size;
• submission_item_id - unique annotation pixel id, each 10m x 10m in size;
• sampleid - unique cluster id (cluster of 100 pixels, each 10m x 10m);          
• timestamp - actual annotation time;
• class_id - unique class id;
• class_name - land cover class name (see thematic resolution above);
• reference_year - reference year for each annotation (2015);
• center_x, center_y - centroids of each 10m x 10m pixel in lon/lat (WGS84).
