Validation data set on land cover changes for RapidAI4EO project

This is a reference data set collected for validation of the monthly land cover maps at a 3m and at a 10m resolution produced in the WP5. The reference data set has been collected by using Geo-Wiki toolbox for visual interpretation of very high-resolution images, including Planet data and Google maps. The data set has been collected over 3 AOIs. Each reference sample site corresponds to a 30m-by-30m box and includes information about monthly land cover type over the period 2018-2020. Land cover legend is the same as in ESA WorldCover map at a 10m resolution (https://worldcover2021.esa.int/).

Fields:

"rowid" – unique row identifier;

"sampleid" – unique sample site identifier in the Geo-Wiki database;

"samplegroupid" – group id with values 257(Portugal), 258 (Belgium), 259(Sicily);

"x_min","x_max","y_min","y_max" – bounding box coordinates of each sample site (30m x 30m), in WGS84

"X2018_1","X2018_2",…, "X2020_12" – dominant land cover class in each sample site in each month from January 2018 to December 2020;

Land cover codes:

10 – Tree cover

20 - Shrubland

30 - Grassland

40 - Cropland

50 – Urban/built-up

60 - Bare/Sparse vegetation

80 - Water

90 - Wetland

110 - Burnt

120 – Not sure
