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. Subglacial landforms are created beneath the ice. They were created during ice expansion. Striae (Glacial striations) are scratches or gashes cut into bedrock by glacial movement, usually by particles embedded in glacier ice. They provide a reliable record of ice flow direction. Geologists map and record evidence during field visits, from air photographs and from Digital Elevation Models (DEMs). Points are added to the 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 Striae 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 points. Each point holds information on the glacial landform type, data source, data reference and its unique identifier.
