UNCLASSIFIEDJacksonville District UAS Team

USACE Mission • Mission:

Deliver vital public and military engineering services; partnering in peace and war to strengthen our Nation’s security, energize the economy and reduce risks from disasters.

• Vision:Engineering solutions for our Nation’s toughest challenges.




Bottom Line Up Front Small UAS brings additional situational

awareness capability to decision makers High fidelity data with rapid delivery from

acquisition to data products. Not a replacement for broader collection tools

such as satellites for traditional aerial collection. Logistics much easier for small sites and priority areas.. (less than 20,000 acres)

Consider all the options and select the best tools for the project requirements.

UAV - History

2005: Starts with ERDC, USGS, University of Florida (UF) and Jacksonville District (SAJ)

2006-2010: Airframe/Payload Development 2010: Transition to operations 2011: SAJ designated UAV Southeast Division

(SAD) Regional Center of Expertise. 2012: New Payload. Mosaic Solution 2012-2013: Production Environment 2014: “Metric” Payload. Gimbaled EO/TIR Video 2015: System diversification 2016: USACE Enterprise Solution




UAV – THE NEED• High resolution imagery for invasive species

management and environmental restoration• High temporal resolution (ability to quickly

reacquire)• Waterproof landing• Responsive to users• Sufficient payload capacity for future

development• We keep finding more uses…




UAS Platforms/Applications

•Pre/active/post construction monitoring•Asset/infrastructure management•Environmental restoration/compliance•Invasive species management (monitoring and biocontrol releases) •Digital Surface Models•FLIR infrared sensor




UAS-Fixed Wing Platforms

• NOVA wing systems• +/-17lbs • Main Mapping System• More skill required• Higher kinetic energy

• eBee Fixed Wing• <5lbs• Smaller Area Coverage• Less skill• Less kinetic energy




UAS-VTOL Platforms

• Mapping where FW not appropriate

• Modular payloads with NOVA platform

• More training to operate

• Phantom VTOL • Attractive Cost• Lower training to operate• Mapping or Video




COE UAS systems




NOVA System Components




NOVA - Airboat Launch




Fully Autonomous 2.7 m Wingspan 15 lbs. w/ Payload ~1000 acres per lift @ 300m

altitude ~50 kilometers per lift @ 300m

altitude ~3.5cm @ 300m altitude Absolute spatial accuracy typically

2-4 meters (no ground control)

NOVA Specifications




Camera Body: Rebel SL1 Sensor: APS-C CMOS 5184x3456 Single Board Micro PC Positioning: Novatel OEMStar (L1 with WAAS) eBee has point/shoot camera and nadir

video DJI Phantom-gimbaled

camera/FLIR/bugdrop, etc…

Standard Mapping Payload Details (MP22)




UAS Applications

•Pre/active/post construction monitoring

•Asset/infrastructure management

•Environmental restoration/compliance

•Invasive species management (monitoring and biocontrol releases)

•Digital Surface Models




HHD Culvert Replacements: C-16 E Side of Lake Okeechobee

Construction Monitoring

Culvert C-16Flown 21 May 2014Mosaic 23 May 2014




Detailed Construction Monitoring

Construction surveillance and documentation




Infrastructure/Asset Management

•NOVA Flight Close to Ground Inspection Time

•Erosion and degradation of levee identified

•Direct application for levee/dike/dam inspections

•FY13 UAV team flew 145 miles of HHD in approx 12 crew days or 12 miles/day

•Emergencies: pre and post damage assessment




Egmont Key Beach Fill Pilot Project with ERDC




Ascension IslandUS Air Force Base Infrastructure Mapping

Challenges- New Environment can only do so much Google Earth scouting.., ELEVATION (Florida”s Flat…), Coordinating with AFB and local gov.




CIR Standard Mapping Payload

Near Infrared spectrum captured useful for vegetation analysis




Species Identification• Resolution sufficient to identify structural

properties of plants

Purple is

Cogon Grass

Orange is

Brazilian Pepper




Species Identification/Classification

Fisheating bay native and invasive delineation




Species Identification/Classification

• Spectral and geometric properties of objects within the image can be used to automatically identify areas of interest.

Species delineation near Lake Placid Florida.




Soo Locks, River Rapids, Geologic Mapping

Soo Locks, Sault St. Marie, Michigan, December 2016Bedrock, Boulders, Rocks, bottom detection




Emergency Response-South Carolina Flooding (2015)

Columbia Canal 201504

-Google Earth

Columbia Canal 20151011

-SAJ Mosaic




Albany, GA Mission Stats

2 people: 6-9 February 2017

6 Sites 3 Debris stockpiles 3 Damage assessments Data Product- RGB

mosaic and 3D Point Cloud volume missions




3100 Gillionville Debris Stockpiles

1) 14962 yds 2) 17818 yds 3) 22830 yds




GOT DSMs?SJ1 Upland Disposal Area, St. Augustine, Florida

Sometimes the vertical relief is not readily apparent in imagery




GOT DSMS?Repair volume and debris removal estimation




Watch Your Step…SJ1 Upland Disposal Area, St. Augustine, Florida

•~1.2 meter washout•Rapid assessment of road/levee conditions




Point Clouds with RGB values

• RGB point clouds can be used to create three dimensional visualizations•BE model can segregate storm debris for volume estimates




Biocontrol Release for ISM




EO and TIR Video Gimbaled Video

• Thermal Infrared spectrum can reveal “hot spots” and temperature variations




Constraints AR 70-62 requires AWR:•Airworthiness Qualification Level (AQL) 3 •Not undergone rigorous airworthiness qualification •Avoid flying over people, roads, homes, etc.•Limited to Line Of Sight operation (LOS)•Depends on conditions, typically 1.5km




Future




Future: Multi-Rotor VTOL for “Everyone”

•“Turn Key”: No assembly and minimal flight planning•COTS•Optional HUD via smartphoneapp•Minimal cost ~$3K per “kit”•Minimal training (2-3 days)•Minimal flight crew

•one operator•one observer

•Think biologists, park ranges, engineers, etc.

•~20 minute flight time•300 gram capacity•Live video feedback•Water quality sampling
