Introduction
Drone Image Survey Requirements
- Ground resolution: 5 cm /pixel
- Overlap: 70%
- Minimum sun elevation: X degrees (to avoid long shadows creating too many false positives. Ignore if overcast.)
- GPS tagging of the images (Exif)
- Timezone set to UTC
Note:
Main Survey Data Collection
Training Data Collection
Low-resolution Survey
(optional) Needed to make a background map of the survey area (used as a layer on slippy map on Webapp).
Data Collection
- Ground resolution: 5 cm /pixel
- Overlap: 70
Data Processing
WebODM cloud version. Data product: Orthomosaic (large geoTiff file). Upload to Mapbox.
