Mary and Rich Darling from Darling Geomatics present on UAV Survey Mapping at the FAA event, Droning On! Navajo Nation in September 2023.

2. Surveying with Drones
for Engineering grade deliverables

3. DRONES: Safe & Cost Effective
Operational Costs
Timeliness (area / duration)
Flexibility / Deployment time
$ $$ $$$
Easy to use / repeatability
Impact on ground activities
Operator’s safety

4. Darling Geomatics UAVs: Regulatory Framework in the US
 FAA Part 107 licensed remote pilots
 Limited to below 400 feet AGL
 Within visual line of sight
 <100 mph
 <55 pound including payload
 Remote ID
 Licensed thermographer
 Licensed surveyors

5. Process
…to hardware
From software…
01 Flight management software
03 Processing software: 2D and 3D Mapping
02 Remotely controlled aircrafts
- Fully autonomous from take off to landing
- Hand launched
- Very light weight
- Made of foam
- Electric powered

6. Sample of Flight Planning Software

7. Mine Mapping - Flythrough

8. Topographic Mapping and Volumetrics
2D / 3D Mapping
Our process produces results with an accuracy of 1 – 2 inches per pixel
resolution and 1 foot topographic contour maps.

9. Flood Stage Mapping

10. Thermal Imaging
• Every pixel has temperature data as well
as latitude, longitude and elevation

11. Orthomosaic Maps and DSMs of Flat and
Mountainous Terrain

12. Ability to Follow Terrain in Mountainous Areas

13. Landfill
Monitoring

14. Topographic Change
Detection/Construction
Monitoring

15. Deliverables
• Deliverables include:
• True color, georeferenced
orthomosaics
• AutoCAD and ESRI
• DSMs/DTMs
• Volumetrics
• Thermal maps
• Flythroughs

16. Summary
If you need measurable, repeatable data
you need to integrate drones with
conventional land surveying

17. Summary
• Increases Safety
• Saves Time
• Saves Money
UAV surveying and mapping:

18. • Drone uses are
limited only by your
imagination

19. Surveying virtually anything……virtually anywhere!
