Geomatics

Task 1
You are responsible for setting out a small building on site. The building is rectangular shaped, and it will be placed on the corner points of A, B, C and D as given in the figure. Your Total Station will be set up on point X.

Task 1a
Calculate the coordinates of point X using the coordinates of CST1, CST2 and readings from your Total Station that are provided.

Task 1b
Produce the data required to set out the corners of the building.
Calculate the total coordinates of the corners of the building, based on the coordinates of point X.

Please include any sketches and hand calculations used to complete tasks at the end of the Report in an Appendix.

Task 2
Some of the disciplines and techniques constituting geomatics are given below and you are to provide a written report to the Client of the IM Marsh Campus.
You are to select at least one* of the below options:
⦁ Photogrammetry
⦁ Geographical Information Systems
⦁ Remote Sensing
⦁ Geodesy

⦁ Laser Scanning
⦁ Global Satellite Positioning Systems
⦁ Unmanned Aerial Vehicles ⦁ Topography
The report should be set out in a professional manner as you are to submit it to the client and you are to evaluate the chosen option and explain:
⦁ How it is/can be linked to the construction process, and
⦁ What are the novel applications and technologies of the chosen option within construction
