Course Objective

This course will provide students with essentials of DTM generation, their testing for accuracy and reliability. DTM application areas will be discussed on practical examples.

Learning Outcomes of the Course Unit

1   Students will be able to differentiate between different data acquisition methods for DTM generation.
2   They will generate DTMs and they will make basic computations on DTMs
3   They will assess the accuracy of the DTMs. They will be able to test DTMs for reliability.
