BSE UNIT 10 LESSON 3 What is a total station?

What is a total station?

• An electronic transit theodolite integrated with electronic distance measurement (EDM) to measure both vertical and horizontal angles and the slope distance from the instrument to a particular point, and an on-board computer to collect data and perform triangulation calculations.

• A manual tool used for measuring only horizontal angles and distances without the use of electronics.

• A GPS device used exclusively for determining the geographic location of a point.

• A software program used for processing survey data without the need for physical measurement tools.

What does photogrammetry involve?

• Taking a single photograph of an object to create a 2D digital model

• Taking overlapping photographs of an object and converting them into 2D or 3D digital models

• Using basic GPS to create topographic maps

• Drawing by hand the topographic maps of an area

What is one of the uses of photogrammetry?

• To create music videos

• To design fashion clothing

• To survey structures or property

• To cook recipes in a virtual environment

What type of images does photogrammetry use?

• Low-resolution underwater photography

• Ultra high-resolution aerial photography

• Black and white photography

• Infrared photography

What can photogrammetry produce?

• A 2D sketch of the landscape

• A fully immersive 3D visual model of the real world

• A simple drawing of a building's interior

• A holographic display of a city

Who can use the photographic document produced by photogrammetry?

• Only surveyors

• Only photographers

• Engineers, architects, and the wider construction team

• Fashion designers

What does LiDAR stand for?

• Light Detection and Ranging

• Light Direction and Ranging

• Laser Imaging Detection and Ranging

• Laser Interference Detection and Ranging

What is LiDAR used for in the context of surveying?

• To create a detailed map of an object's position in space

• To measure the temperature of land and vegetation

• To detect water levels in soil

• To measure the speed of moving objects

Which of the following is NOT a use of LiDAR mentioned in the text?

• Automated driving technology

• Augmented reality

• Advanced topographic surveying

• Underwater mapping

When LiDAR is mounted from a UAV or airplane, what can it measure?

• The speed and direction of the wind

• The height and density of land and vegetation below

• The chemical composition of the soil

• The humidity and temperature of the air
