Abstract: This dataset represents the baseline position of the coastline in 2000 in areas considered to be vulnerable to erosion.

Lineage: An erosion ‘baseline’ was derived from the visible vegetation line shown on the Ordnance Survey Ireland (OSi) year 2000 aerial photography, or where appropriate, the cliff top line, and this was used as the basis for generating the 2030 and 2050 erosion maps.

Purpose: This data provides information required to inform policy in the management of risks associated with coastal flooding and coastal erosion. This is particularly relevant for local authorities in relation to the proper planning and development of coastal areas. The Irish Coastal Protection Strategy Study (ICPSS) is a national study that was commissioned in 2003 with the objective of providing information to support decision making about how best to manage risks associated with coastal flooding and coastal erosion. The Study was completed in 2013 and provides strategic current scenario and future scenario (up to 2100) coastal flood hazard maps and strategic coastal erosion maps for the national coastline.
