A wealth of information can be gleaned by looking at old, historical maps. And viewing these maps alongside KGIS's current data can provide helpful clues to archivists and armchair historians alike.

Therefore, KGIS is now introducing a new interactive mapping application, called Historical Maps, to allow for viewing informative maps from Knoxville and Knox County's past.

We've taken copies of several old maps, and, using GIS software, have rectified (i.e. warped, twisted, stretched) them to closely align with KGIS's current basemap. Since KGIS's basemaps are mapped to a much higher precision, utilizing the Tennessee State Plane Coordinate System NAD 83 horizontal datum and Lambert Conformal projection, many of these older maps do not easily align  themselves. Nevertheless, KGIS staff have attempted to match them to our current map by using control points around which to warp and twist the map...essentially forcing coincidence with our current-day map.

A new Fire Districts map theme has been added to KGIS Maps to display the respective Fire Response service areas within Knox County. Currently, Knox County is divided amongst four different fire response service providers: the Knoxville Fire Dept. (KFD), the Rural Metro Fire Dept. (RMFD), the Karns Fire District (KARNS FD) and the Seymour Volunteer Fire District (SVFD).

A new set of "preliminary" aerials from Winter 2024 have been added to KGIS Maps These aerials are a by-product of the oblique photography capture conducted by  EagleView\Pictometry (on behalf of the Knox County Property Assessor's office and KGIS). The more accurate version of these aerials will be made available later this year.

These 2024 aerials can be toggled on by selecting "2024 Aerial Preliminary" theme in the  "Historical Aerials" section of the Maps panel. ( The default "Aerial" map theme of KGIS Maps still reflects the 2022 vintage aerials.)

While the 2024 aerial image is an accurate representation of ground conditions (at the time taken), it has not been fully rectified and should ONLY be used with the following understanding:

• The imagery has NOT been fully rectified to ground control and is not as accurate as a true orthophoto.
• The imagery may have breaks, gaps, and other issues. This is especially true around elevated features such as bridges and overpasses.

2024 Aerial Oblique images are also available. Access them via the Launch...Pictometry tool in the blue command strip at the top of the KGIS Maps page.

A new set of "preliminary" aerials from Spring 2022 have been added to KGIS Maps These aerials are a by-product of the oblique photography capture conducted by  EagleView\Pictometry (on behalf of the Knox County Property Assessor's office and KGIS). The more accurate version of these aerials will be made available later this year.

These 2022 aerials can be toggled on by selecting "2022 Aerial Preliminary" theme in the  "Historical Aerials" section of the Maps panel. ( The default "Aerial" map theme of KGIS Maps still reflects the 2020 vintage aerials.)

While the 2022 aerial image is an accurate representation of ground conditions (at the time taken), it has not been fully rectified and should ONLY be used with the following understanding:

• The imagery has NOT been fully rectified to ground control and is not as accurate as a true orthophoto.
• The imagery may have breaks, gaps, and other issues. This is especially true around elevated features such as bridges and overpasses.
• Due to weather and ground conditions, the full project was acquired over a 2-3 month time period. Therefore, one will notice that some areas have more vegetatin than others.

2022 Aerial Oblique images are also available. Access them via the Launch...Pictometry tool in the blue command strip at the top of the KGIS Maps page.

The State of Tennessee's COVID-19 Unified Command has produced a GIS-based COVID-19 Dashboard that provides interactive access to statewide maps, data, graphs and charts related to the ongoing emergency. Different panels on the dashboard provide information related to the distribution of cases by county (and age), along with the geographical locations of Assessment (or testing) Sites across the state (including Knoxville and Knox County). Links to this and other COVID-related maps, including additional testing sites, can be found on KGIS's COVID-19 Maps & GIS page.
