Description:Scanned copies of the original Cole-Layer-Trimble (CLT) Property Map books that were filed with the Register of Deeds office in the 1986-1987 timeframe.
KGIS’s original parcel basemap, including the Knox County boundary, was initially digitized using the CLT maps from this timeframe.
It should be noted that many of the CLT Map images will reflect a date in the legend of earlier timeframes than 1986-1987.
The CLT Maps were also mapped at NAD 27 horizontal datum and State Plane Coordinates. Therefore, the coordinates listed in the margin will need to be transformed to KGIS’s current standard (as of 10/31/2023, KGIS’s standard is NAD 83 HARN). For further information, visit the National Geodetic Survey website for datum transformation tools and calculators.
