Difficulty: Easy
Correct Answer: Elevations
Explanation:
Introduction / Context:
Projects in civil, architectural, and landscape design reference heights to a common datum so all participants use consistent vertical control. The term used for a point’s vertical distance above such a datum is fundamental vocabulary in plans and specifications.
Given Data / Assumptions:
Concept / Approach:
An elevation is the vertical distance of a point above (or below) a specified reference plane or benchmark. Elevations allow designers to coordinate floor levels, road grades, drainage, and structural heights. They appear on topographic maps, profiles, sections, and plan callouts.
Step-by-Step Solution:
Verification / Alternative check:
Survey field books list elevations for control points, which are then used to generate contour maps and longitudinal profiles of roads, pipelines, or channels.
Why Other Options Are Wrong:
Plats: legal parcel maps, not height values.
Traverse: a method of sequential surveying measurements, not a vertical value.
Profiles: drawings showing elevation variation along a line, but not the scalar value name itself.
Common Pitfalls:
Confusing an “elevation view” (an orthographic exterior view in architecture) with the numerical elevation value. Context clarifies meaning.
Final Answer:
Elevations
