Service Description:

Shoreline rates show how fast the coast is moving. They show if it is moving out towards the sea or back towards the land.

Our shoreline is in constant movement. Changes to shorelines over time are to be expected due to processes like erosion (rock or sediment being removed) and deposition (sediment being dumped). Much of Ireland’s shoreline was shaped by the last ice-age. In many areas soft sediments were left behind by glaciers. In other areas there are more recent soft sediments such as dunes and sand spits deposited by action of sea or rivers.

Coastal processes can erode these soft sediments. However, climate change driven factors such as sea-level rise and more frequent extreme storms will greatly increase the rate and scale at which coastal erosion is occurring.

Satellite images and aerial photographs show us how the shoreline is changing from year to year. Here Tailte Éireann aerial images between 2000 to 2020/Maxar Worldview 2021 were used to assess the rate or speed of shoreline movement. The data points are spaced 50m apart. The data is split into four classes based on the rates of change. Accretion (deposition), Stable, Moderate Erosion and High Erosion.

It is a vector dataset. Vector data portray the world using points, lines and polygons (area).

The data is shown as points. Each point holds information about the Shoreline Change Rate (metre per year) and the Shoreline Classification.
