ArDOT\u2019s work on this survey control dates back to the 1990\u2019s. This survey control is used primarily by engineers and surveyors of ArDOT to support planning, maintenance, and construction of ArDOT\u2019s transportation infrastructure. Each control station in this dataset has either a precise Latitude/Longitude used for horizontal control or a precise Orthometric Height used for vertical control, or both.\n\nThe accompanying datasheets can be viewed by clicking on the datasheet field url which directly links to the pdf export of the datasheet as maintained in the ARDOT GPS Control database referenced below. \n\nThe database sourced for this information can be found on ArDOT\u2019s Surveys Control webpage here: https://www.arkansashighways.com/surveys_division/ahtd_control.aspx \n\r\n \r\n \r\n \r\n -94.579600\r\n -89.676036\r\n 36.562668\r\n 32.947644\r\n \r\n \r\n \r\n \r\n None\r\n GPS\r\n CONTROL\r\n ARDOT\r\n \r\n \r\n None\r\n None\r\n Arkansas Department of Transportation\r\n Version 6.2 (Build 9200) ; Esri ArcGIS 10.6.0.8321\r\n \r\n \r\n Vector\r\n \r\n \r\n Entity point\r\n 3630\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n NAD 1983 UTM Zone 15N\r\n \r\n 0.9996\r\n -93.0\r\n 0.0\r\n 500000.0\r\n 0.0\r\n \r\n \r\n \r\n coordinate pair\r\n \r\n 0.0001\r\n 0.0001\r\n \r\n meter\r\n \r\n \r\n \r\n D North American 1983\r\n GRS 1980\r\n 6378137.0\r\n 298.257222101\r\n \r\n \r\n \r\n \r\n \r\n \r\n asdi.LOCATION.ARDOT_GPS_CONTROL\r\n \r\n \r\n OBJECTID\r\n Internal feature number.\r\n Esri\r\n \n Sequential unique whole numbers that are automatically generated.\n \r\n \r\n \r\n GPS_Attributes_ID\r\n \r\n \r\n GPS_Attributes_Station\r\n \r\n \r\n County\r\n \r\n \r\n Route\r\n \r\n \r\n Date_Monumented\r\n \r\n \r\n Monumented_By\r\n \r\n \r\n Job_Number\r\n \r\n \r\n Ref_Sta_1\r\n \r\n \r\n Ref_Sta_2\r\n \r\n \r\n Ref_Sta_3\r\n \r\n \r\n AZ_Mark\r\n \r\n \r\n Geodetic_Azimuth\r\n \r\n \r\n Grid_Azimuth\r\n \r\n \r\n RM_1_Description\r\n \r\n \r\n GPS_Attributes_RM_2_Description\r\n \r\n \r\n GPS_Attributes_RM_3_Description\r\n \r\n \r\n GPS_Attributes_RM_1_Azimuth\r\n \r\n \r\n GPS_Attributes_RM_2_Azimuth\r\n \r\n \r\n GPS_Attributes_RM_3_Azimuth\r\n \r\n \r\n GPS_Attributes_RM_1_Distance\r\n \r\n \r\n GPS_Attributes_RM_2_Distance\r\n \r\n \r\n GPS_Attributes_RM_3_Distance\r\n \r\n \r\n GPS_Attributes_Location_Descrip\r\n \r\n \r\n GPS_Attributes_Comments\r\n \r\n \r\n GPS_Lat_Long_ID\r\n \r\n \r\n GPS_Lat_Long_Station\r\n \r\n \r\n Latitude\r\n \r\n \r\n Longitude\r\n \r\n \r\n Ellipsoid_Height\r\n \r\n \r\n Geoid_Height\r\n \r\n \r\n ZONE\r\n \r\n \r\n Horizontal_Datum\r\n \r\n \r\n GPS_Lat_Long_Geoid_Datum\r\n \r\n \r\n GPS_Lat_Long_SX\r\n \r\n \r\n GPS_Lat_Long_SY\r\n \r\n \r\n GPS_Lat_Long_SH\r\n \r\n \r\n GPS_Lat_Long_SG\r\n \r\n \r\n GPS_Elevations_ID\r\n \r\n \r\n GPS_Elevations_Station\r\n \r\n \r\n Elevation_Datum\r\n \r\n \r\n Vert_Determined_By\r\n \r\n \r\n Elevation_Metric\r\n \r\n \r\n SZ\r\n \r\n \r\n GPS_Superseded_ID\r\n \r\n \r\n GPS_Superseded_Station\r\n \r\n \r\n SS_HZ_Datum\r\n \r\n \r\n SS_Zone\r\n \r\n \r\n SS_Latitude\r\n \r\n \r\n SS_Longitude\r\n \r\n \r\n SS_Ellipsoid_Height\r\n \r\n \r\n SS_Geoid_Height\r\n \r\n \r\n GPS_Superseded_Geoid_Datum\r\n \r\n \r\n Bo\r\n \r\n \r\n L1\r\n \r\n \r\n L2\r\n \r\n \r\n L3\r\n \r\n \r\n L4\r\n \r\n \r\n Ro\r\n \r\n \r\n Eo\r\n \r\n \r\n No\r\n \r\n \r\n F1\r\n \r\n \r\n F2\r\n \r\n \r\n F3\r\n \r\n \r\n Delta_Lat\r\n \r\n \r\n U\r\n \r\n \r\n R\r\n \r\n \r\n Bo_Rad\r\n \r\n \r\n Con_Angle\r\n \r\n \r\n Con_Angle_Rad\r\n \r\n \r\n E_Prime\r\n \r\n \r\n N_Prime\r\n \r\n \r\n Easting\r\n \r\n \r\n Northing\r\n \r\n \r\n Grid_Scale\r\n \r\n \r\n Lat_Degree\r\n \r\n \r\n Lat_Min\r\n \r\n \r\n Lat_Sec\r\n \r\n \r\n Long_Degree\r\n \r\n \r\n Long_Min\r\n \r\n \r\n Long_Sec\r\n \r\n \r\n Con_Angle_Degree\r\n \r\n \r\n Con_Angle_Min\r\n \r\n \r\n Con_Angle_Sec\r\n \r\n \r\n SS_Delta_Lat\r\n \r\n \r\n SS_U\r\n \r\n \r\n SS_R\r\n \r\n \r\n SS_Con_Angle\r\n \r\n \r\n SS_Con_Angle_Rad\r\n \r\n \r\n SS_E_Prime\r\n \r\n \r\n SS_N_Prime\r\n \r\n \r\n SS_Easting\r\n \r\n \r\n SS_Northing\r\n \r\n \r\n SS_Lat_Degree\r\n \r\n \r\n SS_Lat_Min\r\n \r\n \r\n SS_Lat_Sec\r\n \r\n \r\n SS_Long_Degree\r\n \r\n \r\n SS_Long_Min\r\n \r\n \r\n SS_Long_Sec\r\n \r\n \r\n data_sheet\r\n \r\n \r\n Shape\r\n Feature geometry.\r\n Esri\r\n \n Coordinates defining the features.\n \r\n \r\n \r\n \r\n \r\n 20200923\r\n FGDC Content Standard for Digital Geospatial Metadata\r\n FGDC-STD-001-1998\r\n local time\r\n \r\n","source_transform":null,"status":"error"}
