Task 1 Planning a Survey

Question 1

what do you need to identify when setting up a total station?

Answer 1

identify a suitable location, consider topography and ensuring that the stations have clear lines of sight to relevant features…

Question 2

how do you extend the line of site when traversing?

Answer 2

by using prisms or reflectors to redirect and extend the line of sight. helps in the presence of obstacles.

Question 3

how can you minimise the impact of obstacles on survey accuracy ?

Answer 3

utilise deflection angles …

Question 4

what is remote sensing technologies?

Answer 4

Remote sensing involves the use of satellite or aircraft-based sensor technologies to detect and classify objects

Question 5

what do you export data in after using the total station?

Answer 5

DXF and text

Question 6

what is the difference between an open and a closed traverse?

Answer 6

open traverse does not from a closed route, closed traverse is commonly used for general land surveys, boundaries. open traverse is less accurate. open traverse is suitable for liner features (roads etc..). the open traverse is more challenging to detects ad adjust errors.
