U.S. Public Land Survey Monument Record City o Madi o 709134 <br /> South Quarter Corner of Section 29, TO7N RO9E, Dane County Wisconsin - <br /> NOTES: l�'" <br /> 1. Date of field work: Dec 2-5 2016 2. This is a found perpetuated monument. Monument(P1)and witness ties(P2-P4) recovered from Irilligili_ ? ' -_monument record dated Feb 16 2004 b Carl Sandsnes with excellent a reement see Line Table . <br /> Bearing differences are due to different coordinate systems.A manhole was found where Sandsnes 4 <br /> shows a tie, but I could not find a chiseled X.The street was resurfaced after 2004, and the manhole Wa 61 <br /> casting may have been reset.Two new witness ties (P5, P6)were set. ® I'.114111 , <br /> 3. Horizontal coordinates are Dane County Coordinates, U.S. Survey feet, NAD83(2007)datum, <br /> computed from a combined adjustment of total station measurements and RTK GPS ION" l(II. <br /> measurements from the Emil Street base station (MAON) at 43°02'12.78285"N, 89°24'34.27099"W , �_�„- <br /> (Easting 814396.30, Northing 469050.00 U.S. Survey feet).The Wisconsin Coordinate Reference <br /> Systems (WISCRS) parameters were used to compute Easting, Northing coordinates. See I <br /> http://gis.cityofmadison.com/Madison_GPS/and www.sco.wisc.edu Horizontal 95% uncertainty <br /> from adjustment=+/-0.06 ft from the base station. <br /> 4. Elevations are in the NAVD88(1991) datum (the original adjustment), determined by same <br /> adjustment used for horizontal position, using the NAD 83(2011)(EPOCH 2010.00) ellipsoid height <br /> of 815.84 ft for the bottom of antenna mount of the Emil St base. The GEOID12 (=12A=12B here) <br /> geoid model was used to compute NAVD 88(2012) elevations, then 0.17 ft subtracted to get NAVD <br /> 88(1991).Vertical 95% uncertainty from adjustment=+/-0.03 ft from the base station. <br /> 5. My easting for P1 is 0.07 ft larger than the 2004 Sandsnes value.,a difference most likely due to datum shift. My elevation is <br /> 0.14 ft larger. <br /> POINT TABLE& NOTES <br /> Monument dimensions in inches, outside diameter(unless noted) <br /> Elevations for witness monuments are shown to allow verification of section corner <br /> monument.
