Aggregate Potential Mapping (APM) aims to identify areas where aggregate is most likely to be found. In this project, \u201cpits\u201d are excavations into Quaternary sediments, and the gravel pit inventory is used to score Granular Aggregate Potential, \u201cquarries\u201d are excavations into bedrock, and the quarry inventory is used to score Crushed Rock Aggregate Potential.Evidence of extraction over time is a key indicator of aggregate potential. While older pits and quarries are important to include, the generally larger operations of recent times receive the highest scores in the APM process. These latter are also of more relevance in that they reflect the demands of modern aggregates production, both in market type and in material standards.This map shows the areas where pits and quarries occur across Ireland. The areas are displayed according to the period of activity.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 county it is located, Pit or Quarry, Local Authority Reference, Site name, Site address, Operator, Status, Mineral, Processing, Products, Additional Details, Hours of operation, Source dataset and Activity Period.Please read the metadata lineage for further information.Please zoom in beyond 1:400,000 to see the data.", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid": 2157, "latestWkid": 2157, "xyTolerance": 0.001, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -5022200, "falseY": -15179500, "xyUnits": 10000, "falseZ": 0, "zUnits": 1, "falseM": 0, "mUnits": 1 }, "copyrightText": "Geological Survey Ireland", "parentLayer": null, "subLayers": [], "minScale": 400000, "maxScale": 0, "referenceScale": 0.0, "drawingInfo": { "renderer": { "type": "uniqueValue", "field1": "ACTIVEPER", "uniqueValueInfos": [ { "symbol": { "type": "esriSFS", "style": "esriSFSSolid", "color": [ 255, 255, 0, 255 ], "outline": { "type": "esriSLS", "style": "esriSLSSolid", "color": [ 104, 104, 104, 255 ], "width": 0.4 } }, "value": "Planning Applications 2004-13: Pits", "label": "Planning Applications 2004-13: Pits" }, { "symbol": { "type": "esriSFS", "style": "esriSFSSolid", "color": [ 255, 234, 190, 255 ], "outline": { "type": "esriSLS", "style": "esriSLSSolid", "color": [ 104, 104, 104, 255 ], "width": 0.4 } }, "value": "Documented 2003: Pits", "label": "Documented 2003: Pits (Cos.
