Dye is usually added to a sinking stream and all possible outlet points (such as springs and rivers) are tested for the dye.Water traces are recorded as a straight line between the location of tracer input (e.g. swallow hole) and detection (e.g. spring), but they don\u2019t show the actual path water may take underground, which is likely to be much more winding.It is mainly used in karst areas to find out groundwater flow rates, the direction the water is travelling underground and to help define catchments (Zone of Contributions).The dataset should be used alongside the Karst Landforms 1:40,000 Ireland (ROI/NI) ITM.Geologists map and record information in the field. We collect new data to update our map and also use data made available from other sources such as Academia and Consultants. It is a vector dataset. Vector data portray the world using points, lines, and polygons (areas).The karst data is shown as lines. Each line holds information on: Tracer Line Unique ID, Input Site, Input Historic GSI Karst Feature ID, Output Site. Output Historic GSI Karst Feature ID, Tracer Test Date, Weather Conditions, Tracer Used, Quantity, Operator, Results, Minimum Groundwater Flow Rate, Hydraulic Gradient (slope of water table), Data Source, Catchment, Peak Concentration, Other Information, Flow Path, County, Length (m), Direction and Quality Checked.", "geometryType": "esriGeometryPolyline", "sourceSpatialReference": { "wkid":
