Validation data set on land cover changes for RapidAI4EO project

<p>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/).</p> <p>Fields:</p> <p>&quot;rowid&quot; &ndash; unique row identifier;</p> <p>&quot;sampleid&quot; &ndash; unique sample site identifier in the Geo-Wiki database;</p> <p>&quot;samplegroupid&quot; &ndash; group id with values 257(Portugal), 258 (Belgium), 259(Sicily);</p> <p>&quot;x_min&quot;,&quot;x_max&quot;,&quot;y_min&quot;,&quot;y_max&quot; &ndash; bounding box coordinates of each sample site (30m x 30m), in WGS84</p> <p>&quot;X2018_1&quot;,&quot;X2018_2&quot;,&hellip;, &quot;X2020_12&quot; &ndash; dominant land cover class in each sample site in each month from January 2018 to December 2020;</p> <p>Land cover codes:</p> <p>10 &ndash; Tree cover</p> <p>20 - Shrubland</p> <p>30 - Grassland</p> <p>40 - Cropland</p> <p>50 &ndash; Urban/built-up</p> <p>60 - Bare/Sparse vegetation</p> <p>80 - Water</p> <p>90 - Wetland</p> <p>110 - Burnt</p> <p>120 &ndash; Not sure</p>
