Developing an Aerial Workflow for UAVs
Jon Skiffington, Director of Product ManagementRobert Parker, Sales Engineer
Overview
• Why UAVs?• Orthoimagery
production workflow• UAV specific concerns
• Post-production workflow• Storage and
distribution
Why UAVs?
• Autonomy (potentially)• 3Ds: Dull, dirty, dangerous• Price• Endurance• Launch and land from virtually anywhere• Potential to drastically reduce image acquisition costs
Why not UAVs?
• Airspace regulation• EUROCONTROL has adopted general regulations• FAA has yet to have a structured plan for US National Airspace
System• Privacy concerns
• Varies by region and country
Orthoimagery workflow
• UAV and camera capabilities• Mission planning• Launch, acquisition, and recovery• Ground control, orthorectification, and georeferencing• QC• Release image
UAVs and support software
• UAV providers• Trimble• senseFly• Silent Falcon• Eurodrone• Many, many (many)
more
• UAV support software• Pix4D• Trimble TBC• Photoscan• Open source tools
Mission planning
• What are you trying to acquire?
• What route will you fly?• What airspace concerns
are in the area?• How many passes will
be required?• Flying remotely or
autonomously?• How will the UAV be
recovered?
Launch/acquisition/recover
• Launch• How much space is
required for launch?• Acquisition
• Typically a grid or back and forth pattern
• How long will the vehicle be airborne?
• Recovery
Image production
• Ground control points• Orthorectification
• Corrects for surface of the earth, tilt of the sensor, etc.
• Correct/warp the image to match know ground control points
• Digital Elevation Model (DEM)
• Georeferencing• QC
Now what?
• You’ve got your imagery…• Storage
• GeoTIFF, MrSID, JPEG 2000, etc.
• Analysis• Esri, Erdas, QGIS, etc.
• Distribution• Express Server, ArcGIS
Server, Image Server, etc.
