Police Officer Map Reading and Navigation Questions and Answers 1 — Questions and Answers
Question 1: On a standard topographic map, what do contour lines that are positioned very close together indicate?
- A gentle slope or flat area
- A body of water, like a river or lake
- A steep incline or cliff (Correct answer)
- A man-made structure, like a road
Correct answer: A steep incline or cliff
Contour lines connect points of equal elevation. When these lines are packed closely together, it signifies a rapid change in elevation over a short horizontal distance, which represents a steep slope or cliff.
Question 2: An officer is conducting a search in a wooded area and travels on a bearing of 65 degrees for 500 yards. To return directly to the starting point, what back azimuth should the officer use?
- 155 degrees
- 245 degrees (Correct answer)
- 295 degrees
- 65 degrees
Correct answer: 245 degrees
To calculate a back azimuth for a bearing that is less than 180 degrees, you must add 180 degrees. Therefore, the correct calculation is 65 + 180 = 245 degrees.
Question 3: A dispatcher provides the grid coordinates "Delta-5" for a reported incident. When looking at the patrol map, which is divided into a lettered and numbered grid, how should an officer locate this position?
- Locate the vertical column labeled "Delta" and the horizontal row labeled "5", and find their point of intersection. (Correct answer)
- Find the row labeled "5" and then move horizontally to the point where it intersects with the line for "Delta".
- Look for a landmark named "Delta-5" directly printed on the map.
- Start at the center of the map and move five units east and then four units north.
Correct answer: Locate the vertical column labeled "Delta" and the horizontal row labeled "5", and find their point of intersection.
A simple letter-number grid coordinate system functions by identifying the intersection of a specified column (often denoted by a letter, like "Delta") and a specified row (denoted by a number, like "5"). The point where this column and row cross is the location of the coordinates.
Question 4: An officer's tactical map has a scale of 1:24,000. Which of the following statements correctly interprets this scale?
- One foot on the map is equal to 24,000 miles in the real world.
- The map is 24,000 times larger than the area it depicts.
- One centimeter on the map is equal to 24,000 feet in the real world.
- One unit of measurement on the map is equal to 24,000 of the same units in the real world. (Correct answer)
Correct answer: One unit of measurement on the map is equal to 24,000 of the same units in the real world.
A map scale expressed as a ratio, like 1:24,000, indicates that one unit of distance on the map (such as an inch or centimeter) represents 24,000 of the same units on the ground. For example, 1 inch on the map equals 24,000 inches on the ground.
Question 5: You are in a rural area and need to orient your map to your surroundings using only a compass. Which of the following is the correct fundamental procedure?
- Point the map's north arrow towards a prominent landmark you can see.
- Guess the direction of north and align the map accordingly.
- Place the compass on the map and rotate the map until the map's north arrow aligns with the magnetic north needle of the compass. (Correct answer)
- Align the compass needle with a road on the map, then rotate your body until you face north.
Correct answer: Place the compass on the map and rotate the map until the map's north arrow aligns with the magnetic north needle of the compass.
The primary method to orient a map with a compass is to place the compass flat on the map and then rotate the map and compass together until the printed north arrow on the map points in the same direction as the north-seeking needle of the compass. This aligns the map with magnetic north and, consequently, the surrounding terrain.
Question 6: When reviewing a standard street or topographic map to identify key infrastructure, which of the following symbols is most commonly used to represent a hospital?
- A star inside a circle
- A small airplane silhouette
- An anchor
- A cross, often in red or blue (Correct answer)
Correct answer: A cross, often in red or blue
While specific symbols can vary between map publishers, a cross (often a Greek cross or a red cross) is the most widely recognized and conventional symbol for a hospital or medical facility on maps.
