The limitations of this map are:Discontinuityof the fluvial outline, due to tributaries not joining up;Misalignmentbetween datasets, due to projection errors;DTMerrors, due to complex automated land cover removal, andMethodologylimitation.The number of potentially affectedproperties is based on the estimated number of postal entries at the time of releaseof the OS Address Layer 2 dataset (April 2006) and is likely to have a high degreeof variability.The coastline of Scotland usedin this analysis is the Ordnance Survey Boundary Line 2005 high-water mark coastline.Although it is unlikely that there are any properties located outside this coastline,the land surface between the low-water mark and the high-water mark can be considerablein places. The coastal flood zone produced...
