TESTING....KGIS has just received a delivery of the 2' contour data covering all of Knox County and the entire KUB service area. The dataset is HUGE! More than 17 gigs in size (as compared with our previous contour dataset size of 5 gigs). And the detail seems to reflect the very high accuracy of the LiDAR data that was flown at a 4 points per meter density back in the spring of 2016. READ MORE...

The Atlantic Group has indicated that its LiDAR flight acquisition, covering all of Knox County and the extended KUB service area, was successfully completed yesterday (Monday March 7th, 2015). READ MORE...

Atlantic delivered the final flight plans for the LiDAR and Aerial photography acquisitions today. As soon as  weather permits, they will fly LiDAR first and then the aerial photography mission will follow within 2-3 weeks. Atlantic was scheduled to be here on February 9th for a project kick off meeting, but we had to reschedule due to weather. The Kickoff Meeting of the Spring 2016 Aerial Topographic Update project has been re-scheduled for Tuesday, Feb 23rd 2016. click here to see the flight paths.

On behalf of KGIS, the Purchasing Division of Knox County TN has posted a Request for Qualifications (RFQ) for the capture, processing, and / or update of digital aerial orthophotography, LiDAR, hydrography, breaklines, spot elevations and contours for all of Knox County and optionally the KUB extended service area. For more information, and inquiries, visit the Solicitations page of the Knox County Purchasing website.

The KGIS Staff has created a web-based Topographic Contour Comparison Tool that will provide departments with a visual look at the different types, and vintages, of contour products being considered as a replacement and/or update to KGIS's aging Topographic Map. (now approaching 8 years old for the western half of Knox County). LiDAR data is a key ingredient to the Landbase Update program of KGIS, having been used for both the 2003 topographic map update (by Merrick) and the 2007-2010 update (by Sanborn).
