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.

(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).
