The City of Knoxville has established a 3D network of survey control
points throughout the city. The Department of Engineering maintains
the network and publishes information for public use. This information
is available via an interactive KGIS website. The City's network
is based on the Tennessee Coordinate System of 1983. Horizontal
coordinates for all points in the network (effective and destroyed)
have been adjusted to conform to the National Spatial Reference
System of 2007. The resulting information was published December
1, 2009. The interactive survey points website
is maintained by KGIS and the City
Engineering Department together, and allows the internet user to locate
the nearest survey control points, print survey control data, print
maps, compute bearings and distances, etc. Your computer screen
resolution should be at least 800 x 600 in order for survey points
website to display correctly.

||Initial publication of survey control points on city website. Becomes effective April 1, 2003.
The first technical document ("About The Data") describes
how to use the geodetic and grid data from the survey control points,
definitions of various survey terms, distance reductions, convergence
angles, and types of elevation datum. The second document contains the
original description of the Tennessee Coordinate System of 1983
The third and fourth documents were sent to local Knoxville surveyors
in January 2003 to explain and clarify platting issues.
Your cooperation is requested in maintaining the survey control network.
Please prevent any damage or destruction to the survey control monuments,
particularly during construction or paving work. Contact the Civil
Engineering Division at 865-215-6100
(Don Jenkins or Richard
Skaggs) to report disturbed or missing survey control points, or with
any possible data discrepancies.
Subdivision Regulations (MSR) for Knoxville and Knox County
requires that surveys must be tied and rotated to the City's survey
control system. Contact the Stormwater Engineering Division
(Molly Hyatt or Ben Davidson) for questions
about survey control requirements and survey plat issues. Many topics
can be answered by downloading either the Plat Review Checklist
or Policy 17
from the Land Development Manual
or the Letter To Area Surveyors.
A general reminder:
is an interactive
mapping KGIS website for general use that displays property ownership,
addresses, buildings, streets, land use zoning, wards, voting precincts,
school zones, CLT map numbers, parcel IDs, recorded deed references,
city limits, political boundaries, etc.
