What does the contour interval on a topographic map represent?
Answer: The vertical elevation difference between adjacent contour lines
The contour interval is the vertical elevation difference between two adjacent contour lines on a topographic map.
When using a baseplate compass in the field, what is the purpose of declination adjustment?
Answer: To account for the difference between true north and magnetic north
Declination adjustment corrects for the angular difference between true geographic north and magnetic north at a given location.
Which map symbol typically indicates a depression or closed low point in terrain?
Answer: Contour lines with tick marks pointing inward
Closed contour lines with small tick marks (hachures) pointing toward the center indicate a depression on a topographic map.
In land navigation, what is a 'bearing'?
Answer: A horizontal angle measured clockwise from north to a target direction
A bearing is a horizontal direction expressed as an angle measured clockwise from north (0°–360°) toward a destination.
What technique involves using two or more known landmarks to determine your current position on a map?
Answer: Triangulation (resection)
Triangulation (resection) uses back-bearings from two or more known landmarks to intersect lines on a map and pinpoint your location.
What does UTM stand for in map coordinate systems commonly used in US outdoor recreation?
Answer: Universal Transverse Mercator
UTM stands for Universal Transverse Mercator, a grid-based coordinate system widely used for land navigation and GPS in the United States.
