Please take care in utilizing these coordinates to eliminate confusion of the two systems. This file is to aid in the use of Real Time Kinematic (RTK) GPS during construction layout. ----------------------------------------------------------------- Datum Transformation Parameters Datum Transformation computation not requested ----------------------------------------------------------------- Updated Default Projection (Transverse Mercator) Definition Updated default projection not requested ----------------------------------------------------------------- Horizontal Adjustment Parameters Northing coordinate of rotation center 805648.477sft Easting coordinate of rotation center 2006308.411sft Rotation about the center point 0°00'00" Translation north -0.016sft Translation east 0.033sft Scale factor 1.00005066 ----------------------------------------------------------------- Vertical Adjustment Parameters Northing coordinate of origin point 798805.431sft Easting coordinate of origin point 1996126.909sft Vertical separation at origin -0.007sft Slope north 3.957ppm Slope east -2.711ppm ----------------------------------------------------------------- Geoid Model Definition GEOID99 (Conus) ----------------------------------------------------------------- Residual Differences Between GPS (WGS84) And Local Coordinates Summary Maximum error Root Mean Square error Point Horizontal 0.102sft 0.014 SAGE - WGS84 Vertical 0.048sft 0.008 SAGE - WGS84 Three-dimensional 0.113sft 0.017 SAGE - WGS84 Point Residuals WGS84 Coordinates Calculated point Local Coordinates FOR DISPLAY ONLY Point SAGE - WGS84 Northing 798805.431sft Point SAGE - Local Latitude 35°56'41.29031"N Easting 1996126.909sft Northing 798805.422sft Longitude 79°00'47.09912"W Elevation 334.484sft Easting 1996127.010sft Height 232.641sft Horz error 0.102sft Elevation 334.436sft Vert error 0.048sft Utilized Horz and Vert 3D error 0.113sft Control Quality quality Point 44 JS 1 - WGS84 Northing 799179.552sft Point 44 JS 1 - Local Latitude 35°56'44.97749"N Easting 2009418.841sft Northing 799179.541sft Longitude 78°58'05.44827"W Elevation 316.905sft Easting 2009418.769sft Height 214.609sft Horz error 0.073sft Elevation 316.870sft Vert error 0.035sft Utilized Horz and Vert 3D error 0.081sft Control Quality quality Point GUESSMAN - WGS84 Northing 829305.437sft Point GUESSMAN - Local Latitude 36°01'42.82700"N Easting 2021989.360sft Northing 829305.463sft Longitude 78°55'32.29549"W Elevation 396.574sft Easting 2021989.387sft Height 294.442sft Horz error 0.037sft Elevation 396.558sft Vert error 0.016sft Utilized Horz and Vert 3D error 0.041sft Control Quality quality Point DUR 35 - WGS84 Northing 803985.433sft Point DUR 35 - Local Latitude 35°57'32.51379"N Easting 2005390.042sft Northing 803985.437sft Longitude 78°58'54.43419"W Elevation 259.572sft Easting 2005390.029sft Height 157.519sft Horz error 0.014sft Elevation 259.583sft Vert error 0.011sft Utilized Horz and Vert 3D error 0.018sft Control Quality quality Point U-4012-1 - WGS84 Northing 801072.437sft Point U-4012-1 - Local Latitude 35°57'03.71159"N Easting 2000541.762sft Northing 801072.434sft Longitude 78°59'53.40748"W Elevation 322.319sft Easting 2000541.762sft Height 220.374sft Horz error 0.003sft Elevation 322.336sft Vert error 0.017sft Utilized Horz and Vert 3D error 0.017sft Control Quality quality Point U-4012-2 - WGS84 Northing 802132.613sft Point U-4012-2 - Local Latitude 35°57'14.19496"N Easting 2002332.587sft Northing 802132.609sft Longitude 78°59'31.62571"W Elevation 310.590sft Easting 2002332.569sft Height 208.605sft Horz error 0.018sft Elevation 310.610sft Vert error 0.020sft Utilized Horz and Vert 3D error 0.027sft Control Quality quality Point U-4012-3 - WGS84 Northing 805139.986sft Point U-4012-3 - Local Latitude 35°57'43.92793"N Easting 2007011.301sft Northing 805139.984sft Longitude 78°58'34.71046"W Elevation 280.445sft Easting 2007011.286sft Height 178.359sft Horz error 0.015sft Elevation 280.463sft Vert error 0.018sft Utilized Horz and Vert 3D error 0.024sft Control Quality quality Point U-4012-4 - WGS84 Northing 805566.796sft Point U-4012-4 - Local Latitude 35°57'48.14711"N Easting 2007656.749sft Northing 805566.796sft Longitude 78°58'26.85782"W Elevation 272.729sft Easting 2007656.739sft Height 170.630sft Horz error 0.010sft Elevation 272.762sft Vert error 0.033sft Utilized Horz and Vert 3D error 0.034sft Control Quality quality
