Surveying Using Theodolite

Front

What equipment is required for surveying using a theodolite?

Back

The equipment required includes a theodolite, tripod, plumb bob, batteries, and log sheets.

Front

What permission is needed to perform a theodolite survey?

Back

Permission from the landowner is required.

Front

How is the theodolite set up?

Back

Place the tripod on the ground above the survey point, ensure the legs are stable, mount the theodolite on the tripod, and use a plumb bob to ensure it's right above the survey point.

Front

What are the steps for leveling the theodolite?

Back

Adjust the tripod to roughly level the theodolite, use leveling screws to center the circular bubble level, and check the tubular vial for fine leveling.

Front

How are horizontal readings taken with a theodolite?

Back

Align the telescope to the first point, use the horizontal tangent screw for precise sighting, set the reading to zero, turn to the second point, and note the angle.

Front

How are vertical readings taken with a theodolite?

Back

Set the reading to zero by aligning the telescope with the vertical angle, sight the first and second points, use the vertical tangent screw for precision, and note the readings manually.

Front

What is the level of accuracy for a theodolite?

Back

The level of accuracy is high for angular measurements.

Front

How is data processed after a theodolite survey?

Back

Data is stored on a log sheet and subjected to trigonometric calculations to convert it into the required format.

Front

What precautions should be taken during a theodolite survey?

Back

Carry extra batteries and wear PPEs like Hi-Vis coats and boots for safety.

Front

What are the advantages of using a theodolite?

Back

Theodolites take accurate angle measurements and are durable and reliable.
