Name: IE_GSI_Structural_Symbols_100K_IE26_ITM

Display Field: DESCRIPT

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: The structural symbols layer is used to describe the geology of an area through dip and strike information. Dip and strike describe the behaviour of the rock bedding plane. To describe a geometric plane two values are required; the angle from horizontal that it is dipping and the direction that it is dipping. Geologists describe the dip direction by the strike value; this is the azimuth perpendicular to the steepest dip of the plane.The measurements that this layer contains give information about the geometry of the rock units under the ground. These measurements are the only way to see if the rocks are folded and faulted and how. With this information we can also start to see why the rocks have the shapes that they do.To produce this dataset, the twenty one 1:100,000 paper maps covering Ireland were digitised. We collect new data to update our map and also use data made available from other sources. This map is to the scale 1:100,000. This means it should be viewed at that scale. When printed at that scale 1cm on the map relates to a distance of 1km.It is a vector dataset. Vector data portray the world using points, lines, and polygons (areas).The structural symbols data is shown as points. Each point holds information on: the dip angle and direction, the strike angle and a description.
