9. Checklist
Set Goals
Met with interested parties
Obtained Software
Researched FAA Requirements
Part 107 / 101 / 336
10. FAA
107
Instructor only takes over ‘for
purposes of safety of flight’
Waiver for flying in airspace
Waiver for flying over people
101 / 336
Drone is registered (101)
Student is operating (***)
Campus is accredited (***)
14. Preflight: FAA and Location Risks
Required Contacts Part 107:
Class B airspace requires FAA Waiver
Operating over people requires FAA Waiver
Required Contacts Sect. 336: MCAS Miramar (Prof.s Wolcott and Moore)
Courtesy Contacts:
Campus PD (dispatch – 619.xxx.xxxx)
Campus Facilities (Dane Lindsay, SDCCD Regional Facilities Officer, 619.388.7823)
Project Area of Operations Visual Survey:
Parking structures = good “home” points
Water tower, possible visual obstruction to VLOS and unknown height
“Measured” water tower height via drone altitude
15. Preflight: Safety of Flight
Mitigate Solar Peak Visual
Risks
Hat
Sunglasses, on strap
Auto Descent puts drone
into sun
Mitigate Injury Risk of
Runaway
Climbing gloves
Keep SA
Harness for DJI Controls
Bluetooth Headset
Wear sunscreen / hoodie
16. Mission
Safely operate UAS to map Miramar
College while providing press
opportunities along with ArcGIS
compatible deliverables as a class project.
17. Mission plan
“Client” -- Prof. Moore requested “map” of the Miramar College Campus
OC Tanner (Copyright 2007) Project Planning Matrix
DroneDeploy.com:
Define project boundary
Define flight elevation (185 feet AGL)
Resumption of “legs” after batt. change: partial leg(s) are re-flown in entirety
Data processing – Photomosaiking
Subscription(s): $83/mo; $249/mo
MapsMadeEasy.com:
Define project boundary
Define flight elevation (185 feet AGL)
Resumption of “legs” after batt. Change: at the last photo point
Data processing – Nope!, because of costs when number of images >250 (3,000 points @$55)
18. Mission plan (CONT’D)
WebODM
Data processing – Photomosaiking
Open Source
Drone2Map
Data processing – Photomosaiking
Subscription(s): $83/mo; $249/mo
Also requires ArcGIS Online subscription:
$42/mo (but for a single user, ArcGIS
Desktop license makes sense @ $800/yr
(basic), or $3,000/yr (standard)
23. Lessons Learned
VLOS was maintained across max length of campus (~2,436 ft, or 0.46 mi)
Deliberately picked Inspire for VLOS
DroneDeploy.com flight plan
Closely monitor flight at low-battery-initiated “Return Home”
Inefficient leg resumption – restarts leg
RF Interference
Aborted several legs, possibly due to other sUAS in class
MapsMadeEasy.com
During “Return Home” manual photography cancels “Return Home”
Efficient leg resumption
Each battery change requires “reloading” the flight; glitches will occur
Taking command = returning to reprogram flight
Human Factors = 80% of your problem
Law Enforcement pre-planning pays off
People don’t really talk to the guy in a hardhat and safety vest
Expect adults around children to ACT like children…
Knuckleheads will drive through your cones and “Home”
25. Mission
Safely operate UAS to map Miramar
College while providing press
opportunities along with ArcGIS
compatible deliverables as a class project.
27. GIS Integration
What is GIS? Why Do I Need GIS?
Checks GEOTIFF markers
Plots image onto layered map
Allows for multiple assets to be
handled
Visualization, BABY!!

Two or three maps to be combined
with DroneDeploy
Processed as backup
$47 for Open Source Map (WebOSM)
4 days of attempts on low end

$1500 /yr for Drone2Map
Winner!
One slide. One image.
How many images do you think we needed?
2891 Photos, processed by a $1500 software package layered on top of another $1500 program – ArcMap and Drone2Map from ESRI
Cover GEOtiff format
Cover GIS in brief
Break down Flight Plan
Break down Mosaic processing
Why… DroneDeploy $83-250 a month or $47 for WebODM, or Drone2Map plugin for ArcGIS
