Week 10 - Geodesy and Cartography

What does a theodolite mainly measure?

• Distances and heights

• Horizontal and vertical angles

• Temperature and wind speed

• Land area in square meters

Why is a total station useful for urban planning in Astana?

• It doesn’t need electricity

• It is cheaper than a theodolite

• It works without a tripod

• It measures angles and distances quickly

What is a limitation of the theodolite?

• It only measures angles, not distances

• Requires a power source to operate

• Can measure angles only in one direction

• Limited by line of sight obstructions

Which tool is better for a highway project near Shymkent?

• Traffic management software
• Total station because it is faster

• Theodolite because it uses a laser

• Total station because it is manual

What does the total station use to measure distances?

• A tape measure

• Optical lenses

• A laser or infrared beam

• Mechanical measurements

Match the tool to its main feature

• Measures angles manually

• Theodolite

• • Holds the tool steady

• • Telescope

• • Measures angles and distances electronic

• • Tripod

• • Helps see distant objects

• • Total Station

Match the term to its definition

• • Tasks done by a tool automatically

• • Automation

• • Line marking land edges

• • EDM

• • Ability to measure accurately

• • Boundary

• • Measures distances with a laser

• • Precision

Match the advantage to the tool

• Laser

• Helps measure distances quickly in modern tools

• • Theodolite

• • Keeps tools stable on Kazakhstan’s uneven land

• • Tripod

• • Used for simple angle measurements in rural areas

• • Total Station

• • Combines angle and distance data for urban projects

Put these steps in order to use a theodolite

• • Level the tool with screws

• • Read the angles from the circles

• • Set up the tripod on stable ground

• • Aim the telescope at the target

Order these features by how they improve a total station

• • Uses a telescope for aiming

• • Measures distances with a laser

• • Stores data digitally

• • Connects to a computer
