FUNDAMENTAL SURVEYING Surveying Equipment and Technology

Question 1

What is the primary advantage of a robotic total station over a conventional total station?

Accepted Answer

One-person operation via remote control from the prism pole

Answer

Higher angular accuracy

Answer

Lower cost

Answer

Works better in rain

Question 2

What does 'LiDAR' stand for and what is it used for in surveying?

Accepted Answer

Light Detection and Ranging — used to collect dense 3D point clouds of terrain and structures

Answer

Laser Imaging Distance and Ranging — used only underwater

Answer

Light Imaging Data and Recording — used for aerial photography

Answer

Linear Distance and Ranging — used for tape measurements

Question 3

What is the function of a retroreflective prism in total station surveying?

Accepted Answer

To reflect the EDM laser beam directly back to the instrument for distance measurement

Answer

To amplify the EDM signal

Answer

To measure vertical angles independently

Answer

To provide a target for manual sighting only

Question 4

What type of level uses a compensator to automatically maintain a horizontal line of sight?

Accepted Answer

Automatic (self-leveling) level

Answer

Dumpy level

Answer

Tilting level

Answer

Digital level

Question 5

What is the advantage of a digital level over an optical automatic level?

Accepted Answer

It electronically reads bar-coded rods, reducing reading errors and allowing automatic data recording

Answer

It works without a rod

Answer

It is more accurate over long sights

Answer

It does not require a compensator

Question 6

What is the role of a CORS (Continuously Operating Reference Station) network in GPS surveying?

Accepted Answer

It provides real-time or post-processed corrections to improve GPS accuracy

Answer

It amplifies GPS signals in urban canyons

Answer

It replaces the need for a GPS receiver

Answer

It records seismic data
