One of the main problems encountered in the ESDI making is to determine what spatial data sets should be classified to the ‘Land Use’ theme. This is due to different understanding of this term by experts or the scientific communities. The article presents the results of analyses of the spatial data sets submitted in the ‘Land Use’ theme in Spain in recent years. The changing entries number in monitoring sheets over the years shows that the creation process of IDEE is still highly dynamic. There is a need to determine the scope of individual themes, need to supplement or resignation of certain data sets, and standardize content of others. These claims are also reflected in the ‘Land Use’ theme. A large variety of spatial data sets relating especially to the current land use indicates a lack of clarity of what data should be submitted.
