13 Land Surveying and Site Analysis

Surveying is defined as the process of measuring and mapping land areas. Which of the following is a reason why land surveys are performed?

• To determine property boundaries

• To plant crops

• To build furniture

• To cook food

PPE that should be worn when conducting surveying exercises includes:

• Safety helmet, high-visibility vest, safety boots, and gloves

• Lab coat, safety goggles, and sandals

• Swimsuit, flip-flops, and sunglasses

• Chef's hat, apron, and oven mitts

Survey equipment is used for which of the following purposes?

• Measuring and mapping land features

• Cooking food

• Repairing vehicles

• Planting trees

Basic methods used to measure distance include which of the following?

• Using a measuring tape, ruler, or odometer

• Using a thermometer, barometer, or hygrometer

• Using a stopwatch, calendar, or clock

• Using a protractor, compass, or set square

The process of correctly setting up, leveling, and measuring with a dumpy level, auto level, and laser level involves which of the following steps?

• Setting up the instrument on a tripod, leveling it using foot screws or automatic compensator, and taking measurements through the telescope or laser receiver.

• Placing the instrument directly on the ground, turning it on, and reading measurements without leveling.

• Holding the instrument by hand, pointing it at the target, and recording the value displayed.

• Mounting the instrument on a wall, adjusting the focus, and measuring distances by estimation.

Differential and profile leveling are methods used in surveying. Which statement correctly defines both processes?

• Differential leveling determines the difference in elevation between points, while profile leveling measures elevations along a line at regular intervals.

• Differential leveling measures horizontal distances, while profile leveling measures vertical angles.

• Differential leveling is used for mapping contours, while profile leveling is used for setting out curves.

• Differential leveling and profile leveling both only measure horizontal distances.

Identify three general soil categories and their characteristics.

• Sand, silt, and clay; sand is coarse and drains quickly, silt is smooth and retains some water, clay is fine and holds water well.

• Gravel, peat, and loam; gravel is large and rocky, peat is organic and spongy, loam is a mix of sand and clay.

• Chalk, peat, and humus; chalk is alkaline, peat is acidic, humus is rich in nutrients.

• Rock, sand, and peat; rock is solid, sand is loose, peat is organic.

A basic soil quality test involves which of the following steps?

• Collecting a soil sample and analyzing its texture, color, and moisture

• Measuring the air temperature above the soil

• Observing the number of insects on the soil surface

• Counting the number of rocks in the soil

Laying out a square corner involves which of the following methods?

• Using the 3-4-5 triangle method

• Measuring with a protractor

• Drawing freehand lines

• Using a compass only

What is surveying?

• Taking essential measurements to determine accurate points or places on land

• Building structures

• Planting trees

• Drawing maps
