Date of field work: May 4&July 1,2021 2.This is a found perpetuated monument. Ties P2-P3 found per Feb 4 1987 monument record by Ross Michaels. Ties P6-P9 found per Apr 1 2004 monument record by Carl Sandsnes. 0 Ties P4-P5& P7-P8 found per Aug 31 2010 monument record by Frank Lapacek. ititil Holding my coordinates for P2-P9, best-fit of P1 from Lapacek 2010 ties fits to 0.03 ft& puts P1 0.02 ft north &0.01 ft west of my P1. Best-fit of P1 from Sandsnes 2004 ties (excluding P8 0.08 ft off)fits to 0.02 ft&puts P1 0.07 ft north &0.03 ft west of my P1. For comparison, published Sandsnes 2004 coordinates of P1 are 0.12 ft north and 0.14 ft west of my P1. Some of the latter difference may be datum shift. Sandsnes 2004 elevation of P1 not directly comparable since reset in 2010. 3. Horizontal coordinates are Dane County Coordinates, U.S. Survey feet, NAD datum, computed from a combined adjustment of total station measurements and RTK GPS measurements from the Emil Street base station (MAON) at 43°02'12.78285"N, 89°24'34.27099"W(Easting 814396.30, Northing 469050.00 U.S. Survey feet). The Wisconsin Coordinate Reference Systems (WISCRS) parameters were used to compute Easting, Northing coordinates. See http://gis.cityofmadison.com/Madison_GPS/and www.sco.wisc.edu Horizontal 95% uncertainty from adjustment=+/-0.04 ft from the base station. 4 Elevations are in the NAVD88(1991) datum (the original adjustment), determined by same adjustment used for horizontal position, using the NAD ellipsoid height bottom of antenna mount of the Emil St base. The GE0D12 (=12A=1 here) eoidmodel was used to compute NAVD 88(2012) elevations, then 0.17 ft subtracted to get NAVD 8B(1801). Vertical 8596 uncertainty from adjustment= +cO.O2ft from the base station. POINT TABLE& NOTES Elevations for witness monuments are shown to allow verification of section corner monument. Note that witness monuments may not be stable.
