A landslide is the movement of material down a slope. This includes rock, earth, mud and peat. Landslides in Ireland mainly occur on steep mountain slopes.
A landslide susceptibility map shows areas where a landslide could occur, how likely it will occur and what causes them. The likelihood is measured from low to high.
The map is created using a method called the Unique Condition Unit (UCU).
A unique condition unit is an area with a set of ground types. It tells us what the soil type is, what the slope is (angle of the ground) and where water flows.
When many landslides occur in a unit, the map will show high landslide susceptibility.
The landslide susceptibility classification map is to the scale 1:50,000. This means it should be viewed at that scale. When printed at that scale 1cm on the map relates to a distance of 500m.
It is a vector dataset. Vector data portray the world using points, lines, and polygons. A polygon represents an area.
The landslide susceptibility data is shown as polygons. Each polygon gives information on the description of landslide susceptibility (High, Low, Moderately Low etc).
