All questions relate to a geodetic study of Rland, a fictitious island. Rland is thought to be a geologically stable land mass in that there are no significant faults causing deformation between survey marks. However, the entire land mass is free to rotate and subside. Consider the geology as being similar to that of Barbados.
Problems relate to a geodetic study of Rland concerning developments of geodesy for surveying and mapping in the modern satellite era. Questions 1 to 4 require an investigation of the existing geodetic network for horizontal control in relation to modern datums while Questions 5 and 6 relate to vertical control.
QUESTION 4 [20 marks]
On the basis of findings from the geodetic study, and from your understanding of modern geodesy, provide….
