A. Analysis of UAS data processing results
Topic 4: GIS Analytics
Analysis of UAS data processing results
Outline
- Compare survey data and errors from different flights
- Recognize differences in geoprocessing products generated by different softwares
- Understand significance of using GCPs in the processing and their impact on the final products
- Recognize what processing steps need to be modified in order to improve particular errors
- Understand what causes the ‘Bowl effect’ and know the solutions to fix it
- Execute distance, area and volume measurements
Lecture
Supplemental materials

- Image residuals, camera calibration and impact of GCPs: Evaluation of structure from motion for soil microtopography measurement
- Alternative to GCPs - RTK/PPK equipped UAS: Do RTK/PPK drones give you better results than using GCPs?
