{ "currentVersion": 11.1, "cimVersion": "3.1.0", "id": 0, "name": "LIDAR_Ground_Truth_Surveys", "type": "Feature Layer", "description": "The Environment Agency Ground Truth Surveys is an archive of elevation points and attribute information that have been independently surveyed to verify the accuracy of the EA's LIDAR Timestamped surveys. Captured by various independent surveyors, a ground truth survey is a collection of a few hundred points captured on a flat, unambiguous surface such as a tarmac car park or tennis court using GPS. Each ground truth point has an accuracy of +/-3cm RMSE.\nEach ground truth point contains the following attributes:\n\u2022\tGT Survey Name: The unique ground truth the point was surveyed as a part off. Each Survey is a collection of a few hundred individual points.\n\u2022\tPolygon ID: The unique polygon ID the Ground Truth Survey was captured under.\n\u2022\tEasting: The OSGB easting position of the point.\n\u2022\tNorthing: The OSGB northing position of the point.\n\u2022\tElevation (m): The elevation of the surveyed point in metres. \n\u2022\tSurvey Method: The survey method used; either Smartnet, RTK or Stop-Go.\n\u2022\tSurface: The surface the point was taken on.\n\u2022\tSurvey Date: The Date of the survey.\n\u2022\tSurvey Year: The Year of the survey.\n\u2022\tGPS Day: The GPS day of the survey. The first 2 digits represent the year and the final 3 the day within the year starting at 0 for January 1st.\n\u2022\tTransformation Model: the OS Transformation model used, either OSTN\u201902 or OSTN\u201915.\n\u2022\tGeoidal Model: the OS Geoidal model used, either OSGM\u201902 or OSGM\u201915.", "geometryType": "esriGeometryPoint", "sourceSpatialReference": { "wkid": 27700, "latestWkid":
