Description: In terms of time scale in geology, Quaternary is the present-day time and it began 2.6 million years ago. A lot of this time period relates to the Ice Age. Quaternary geomorphology is the record of landscape features that were created in the last 2.6 million years. In Ireland, movement of glaciers and ice sheets created many of these features. A trimline is a clear line on the side of a valley formed by a glacier. The line marks the most recent highest extent of the glacier. The line may be visible due to changes in color to the rock or to changes in vegetation on either side of the line.Geologists map and record evidence during field visits, from air photographs and from Digital Elevation Models (DEMs). Lines are drawn on a map to show where features are found.We collect new data to update our map and also use data from other sources.This map shows the currently mapped trimlines in Ireland.This 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 (areas).The data is shown as polygons. Each polygon holds information on the glacial landform type, name, data reference, captured altitude(m, minimum altitude(m) ) and its unique identifier.
