Course programme
On successful completion of this course you will be able to:
- Summarise the geometry and spectral properties of vertical aerial photographs and evaluate their importance in the use of aerial photography for deriving mapping products
- Apply the basic principles of softcopy photogrammetry to a range of remotely sensed datasets
- Interpret aerial photographs in the context of the physical and human environments
- Evaluate elevation data products derived from stereo image pairs and assess their use for a range of applications
- Prepare orthophotography from standard frame aerial photography and assess the quality of the output.
