Land Use

Land use information is derived from the Land Cover Map 2000 (LCM2000) and from the Land Cover Map 2007 (LCM2007). In both cases, the raster variant of the land cover maps with 25 m cell size was used as input. Users should note that the classes used in LCM2000 and LCM2007 are not directly comparable and therefore land cover change in catchments from 2000 to 2007 cannot be easily analysed based on these two datasets. For the same reason, even the generalized NRFA Land Cover Classes cannot be compared between 2000 and 2007.

Since 2016, the proportion of urban area shown on the land use pages is calculated directly from the Land Cover Maps as indicated below. The urban extent parameter previously presented on NRFA website was the URBEXT2000 catchment descriptor. URBEXT2000 for each station is still available along with URBEXT1990 as an FEH Catchment Descriptor.
