1. Geodetic Control
The City of Winchester will make available all Geodetic Control information to be used for survey purposes. All coordinate values for these survey points shall be in Latitude Longitude using the North American Datum (NAD83) with a 1997 HARN adjustment. All Points should be projected into Kentucky State Plane System using the North American Datum (NAD83) with a 1997 HARN adjustment, Kentucky North Zone, FIPS zone 1601. All measurements shall be in US Survey Feet. The City’s Geodetic Control network can be accessed through the Commonwealth of Kentucky National Geodetic Survey Advisor, see http://nas.state.ky.us.
The surveyor or engineer preparing the plans shall tie the boundary into at least two points of the above mentioned survey control network. The basis of bearing for the plans must be in NAD83(1997) coordinate system.
If the Kentucky Geodetic Survey control points are not available and cannot be provided to the surveyor or engineer the above mentioned requirements will be waived. In these cases, the surveyor or engineer shall note and describe two reference locations. These locations will be used to tie the survey or plan to the state plane coordinate system.
2. Data Format
In addition to as-built plans submitted in hard-copy format, a digital copy of the file used to produce the hard-copy plans shall be provided in AutoCAD Drawing Format (Version 14 or greater). In addition to the AutoCAD Drawing file, a PostScript file will be created from the original software package, containing a “reproduction” of the hard-copy as-built plans.
All digital files must be mapped to scale and submitted to the city on 3.5" floppy disk or CDROM.
3. Data Layer Requirements
In order to evaluate the accuracy and promote the efficient use of the data in the City’s GIS, digital file layering has been standardized. The digital data shall use the following layering scheme:

4. Manually Prepared Plats
Survey data (for manually prepared plats) must be submitted in an ASCII text file within a rigidly defined tabular format.
5. Adjustments to these requirements
The City of Winchester may wave or adjust requirements specified herein, upon a finding that the strict adherence of the requirements does not apply or is contrary to the long-term maintenance of the GIS of the City of Winchester.
6. Review of Digital Data
All digital data will be reviewed for the following criteria:
1. Correct layering
2. Closure of the geometry of the boundary
3. Verification that digital and hardcopy maps are consistent
4. Correct geographical position (i.e. correct coordinate values for final submission
The Applicant will be given ten (10) working days from the day of notification of errors to correct and resubmit the correct digital file prior to final approval by the Winchester Clark County Planning Commission.
