This dataset contains borehole location, depth, and temperature data for 6,112 points compiled from Southern Methodist University\u2019s (SMU) National Geothermal Data System node and individual state observations downloaded from the Association of American State Geologists (AASG) Geothermal Data Repository. The database includes well identification (FID, well name, well status), location (county, state, latitude/longitude, spatial reference system [SRS] used to map points), depth of temperature measurement, temperature (°C), information source, and parent dataset accessible at https://maps.nrel.gov/geothermal-prospector (e.g., SMU or AASG). The data have been filtered for the low temperature range of 30 °C to 150 °C. Last updated 2016. This layer is symbolized by the WSGS into three categories: below the temperature for binary organic Rankine cycle power generation (<57°C; Erkan and others, 2008), above the boiling point of water at sea level (>100°C), and between these two thresholds (57-100°C).<\/SPAN><\/P><\/DIV><\/DIV>", "geometryType": "esriGeometryPoint", "sourceSpatialReference": { "wkid": 102100, "latestWkid": 3857, "xyTolerance": 0.001, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -20037700, "falseY": -30241100, "xyUnits": 10000, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 }, "copyrightText": "https://maps.nrel.gov/geothermal-prospector", "parentLayer": null, "subLayers": [], "minScale": 0, "maxScale": 0, "referenceScale": 0.0, "drawingInfo": { "renderer": { "type": "classBreaks", "authoringInfo": { "type": "classedColor", "colorRamp": { "type": "algorithmic", "algorithm": "esriHSVAlgorithm", "fromColor": [ 245, 245, 0, 255 ], "toColor": [ 245, 0, 0, 255 ] }, "classificationMethod": "esriClassifyManual" }, "field": "temp_c", "classificationMethod": "esriClassifyManual", "minValue": 30.0377, "classBreakInfos": [ { "symbol": { "type": "esriSMS", "style": "esriSMSCircle", "color": [ 255, 255, 0, 255 ], "size": 4, "angle": 0, "xoffset": 0, "yoffset": 0, "outline": { "color": [ 0, 0, 0, 255 ], "width": 0.6 } }, "classMaxValue": 55.635812751677875, "label": "30 -
