What is a Property Survey?

• A survey that ignores the curvature of the Earth.

• A survey that establishes property corners, boundaries, and areas of land parcels.

• A survey used to prepare maps showing location of natural and man-made features.

• A survey that determines the difference in height between a plane of sight and a point.

What is the purpose of a Topographic Survey?

• To establish property corners and boundaries.

• To prepare maps showing location of natural and man-made features and elevations of points on the ground.

• To determine the difference in height between a plane of sight and a point.

• To locate points and elevations for civil engineering projects.

What is Differential Leveling?

• A survey that combines property and topographic surveys.

• The process of determining the difference in height between a plane of sight and a point.

• A procedure to determine the grain size distribution of soil.

• The process of changing the topography of a property.

What is a Benchmark in surveying?

• The process of changing the topography of a property.

• A survey that ignores the curvature of the Earth.

• A relatively permanent object bearing a marked point whose elevation is known or assumed.

• A complete record of all measurements made during the survey.

What is the Plastic Limit of soil?

• A procedure to determine the grain size distribution of soil.

• The consistency of fine-grained soils as the water content varies.

• The minimum moisture content at which the soil will begin to flow when subjected to a small shearing force.

• The minimum moisture content at which the soil can be rolled into a thread one-eighth of an inch in diameter without crumbling.

What is a Site Survey?

• A survey that establishes property corners and boundaries.

• A survey used to prepare maps showing location of natural and man-made features.

• A survey that determines the difference in height between a plane of sight and a point.

• A combination of a property survey and a topographic survey for a single property.

What is the purpose of a Construction Survey?

• To determine the difference in height between a plane of sight and a point.

• To establish property corners and boundaries.

• To prepare maps showing location of natural and man-made features.

• To locate points and elevations for civil engineering and architectural projects.

What is a Control Survey?

• A survey that establishes a network of horizontal and vertical control points.

• A survey used to prepare maps showing location of natural and man-made features.

• A survey that determines the difference in height between a plane of sight and a point.

• A combination of a property survey and a topographic survey for a single property.

What is Land Surveying?

• The Process of building structures on land.

• The science of determining relative positions of points on or near Earth's surface.

• The study of weather patterns.

• The analysis of soil samples.

What term describes the vertical distance from a datum to a point or object?

• Elevations

• Grading

• Closure Error

• Sieve Analysis
