TNBMP – Elevation (DTM)



• Approximately 20% coverage in the state

• Estimated cost of remaining 80% is: $7-8 million

LiDAR coverage prior to 3DEP



• Perfect timing for Tennessee !!• Program began in 2014, entering 3rd year of awards• USGS QL 2 (2 pt/sq. meter and 10cm vertical)

• DEM• Hydro-flattened breaklines• Unclassified and classified point cloud (.las files)• Building footprints

• 2014 Award – acquired December 2015 (Woolpert)• 2015 Award – acquired Spring 2016 (Woolpert)• Leveraging the USGS GPSC contract

• USGS BAA – Summer 2017• Local Funding Commitment – Aug 2017• State Proposal Submission – Sept 2017• USGS Awards – Nov 2017• LiDAR Acquisition (leaf-off) – Feb/March 2018• Data Deliveries – Late fall 2018

• STATEWIDE COVERAGE COMPLETE !!

2017-18 Timeline/ Acquisition:



• Develop a business plan and identify stakeholders• Find an ‘anchor institution’ for funding (TDOT)• Economies of Scale – large geographic areas drive

down costs• Don’t ask USGS for too much funding – average

awards were around 35% of project total• Have a statewide goal in mind• Persistence pays off – 5 year effort to date
