Field methods and spatial workflows

Selected field activities document mission design, data acquisition, equipment preparation, post-flight processing, and geospatial technology demonstration.

Mission planning and geospatial processing

UAV survey design and post-flight processing were treated as a connected workflow. DroneDeploy was used to configure mission geometry for Phantom 4 Pro V2 and Mavic 2 Pro deployments, with parameters adjusted to site extent, surface complexity, and the intended mapping product. The collected imagery was then reviewed through photogrammetric and GIS workflows to support orthophoto generation, LiDAR-assisted interpretation, quality review, and preparation of GIS-ready datasets.

WorkflowMission geometry · overlap and altitude · nadir/oblique acquisition · photogrammetric processing · GIS review · analysis-ready outputs

Field deployment and site observation

Mission execution was paired with field observation to relate aerial imagery to terrain, land use, infrastructure and environmental conditions.

MethodsUAV capture · visual inspection · site documentation

Platform preparation and equipment checks

Pre-deployment checks focused on the UAV platform, payload configuration, equipment condition and coordinated field procedures.

PurposeConsistent acquisition and defensible field records
