Spatial level (spatial units)

Spatial units are regarded as territorial units delimited at different spatial levels. A spatial unit can be considered for example a territorial unit defined according to the NUTS (Nomenclature of Units for Territorial Statistics) or LAU (Local administrative units) classification, including, for example in the case of the Czech Republic, the levels of municipalities (LAU 2/NUTS 5), districts, (LAU 1/NUTS 4), regions (NUTS 3), etc. The selection of a spatial level and the definition of spatial units are key phases within the process of brownfield prioritization because it determines the selection of factors and indicators which will be applied in the prioritization methodology (i.e., the majority of data are available only at the higher regional levels NUTS1-3, only some at the municipal level.)
