Punishment for defacing a monument
In the Summer of 1998, the office of the Medina County Sanitary Engineer began the process of "GPS Monumetation."
The purpose of "GPS Monumentation" is to establish a countywide coordinate system that would enable the
Sanitary Engineers' to geographically locate its water and sanitary utilities for mapping purposes. "GPS Monumentation"
is the first step in the process of transfering all of the Sanitary Engineer's utilities to a G.I.S. (Geographic
Information System) application to benefit the entire county.
As of October of 2003, there are 54 monuments in the Medina County GPS Network. Forty-six of these monuments are
"Blue-booked" by N.G.S. (National Geodetic Survey). The "Blue-booking" process publishes monuments
in to a national database maintained by N.G.S. Of these 46 monuments, the office of the Medina County Sanitary
Engineer used 22 existing monuments with in the county and set 27 new monuments. A majority of the "Blue-booked"
monuments are "First Order Horizontal" and "Fourth (ClassII) Odrer Vertical" according to N.G.S.
classifications. In addition, 8 new monuments were added in the Fall of 2002, but were not "Blue-booked."
These monuments are- SH28, WE29, CH30, HO31, SP32, CWL9, CWL42, and ABBOTTAZ.
Datasheets are availible for all of the 54 Medina County G.P.S. Control monuments. Explaination of the datasheets
is as follows:
1.The horizontal data was obtained from N.G.S. ("Blue-booked" monuments only.) These monuments include-
MC01, YO02, LT03, LT04, LT05, LV06, LV07, YO08,YO09, LV10, BR11, GR12, HI13, HI14, ME15, LT16, CH17, CH18, LF19,

CHRIS, 3G3A, 2C, COR11, M176, R176, ABBOTT, HOMERAZ, LC96, LC99.
2.The vertical data was obtained from N.G.S. These monuments include- M176, R176, HOMERAZ
3.The remaining data was calculated by Geodetic Consulting Services of Columbiana, Ohio. For a further explaination,
please contact the Medina County Sanitary Engineer.
4. For a further explaination of all other data, please contact the Medina County Sanitary Engineer.
