CORINE Land Cover is one of the most relevant Use (LUC) databases in Europe because its degree detail and long time series. Although some studies have assessed uncertainty inconsistencies database for specific years periods, no work has been found that analyses all available series (1990–2018). In this study, we analyse a Spanish region (Asturias). To end, compare status layers (CLC) changes (CHA) each mapped periods: 1990–2000, 2000–2006, Citation2006–2012, 2012–2018. Results show how CLC CHA provide different information, especially after change production Spain 2012. The last two editions (2012, 2018) lot technical make use very uncertain. addition, mixed categories, whose definition imprecise and, therefore, more uncertain, are behind detected both types (CHA, CLC).
