GPS Calibration Report TIP Number B-3421 Coordinate System US State Plane 1983 Zone North Carolina 3200 Horizontal Datum NAD 1983 (Conus) Vertical Datum NAVD-88 Geoid Model Geoid03 (Conus) NC Sub Grid Coordinate Units US survey feet Distance Units US survey feet Height Units US survey feet ------------------------------------------------------------------------------- LOCAL SITE INFORMATION Localized around BUFFALO 2 Latitude N/A Longitude N/A Site Scale Factor N/A Height N/A ------------------------------------------------------------------------------- The North Carolina Department of Transportation uses a Localized Coordinate System which is very similar to North Carolina Zone 3200 from which it is derived. 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 600261.407sft Easting coordinate of rotation center 1545027.921sft Rotation about the center point 0°00'00" Translation north -0.385sft Translation east 3.658sft Scale factor 1.00014872 ------------------------------------------------------------------------------- Vertical Adjustment Parameters Northing coordinate of origin point 602892.604sft Easting coordinate of origin point 1520417.689sft Vertical separation at origin 0.163sft Slope north -1.735ppm Slope east -1.125ppm ------------------------------------------------------------------------------- Geoid Model Definition Geoid03 (Conus) NC Sub Grid ------------------------------------------------------------------------------- Residual Differences Between GPS (WGS84) And Local Coordinates Summary Maximum error Root Mean Square error Point Horizontal 0.010sft 0.002 M 048 -
