Map and Spatial Interpretation Flashcards

On an aerial map, which view perspective is shown when streets appear as flat lines and buildings appear as rectangles with no depth?

Answer: Bird's-eye (orthographic) view

A bird's-eye or orthographic view looks straight down from above, showing features as flat shapes with no perspective distortion.

An officer must navigate to an address on the 1200 block of Oak Street. Which building number range defines the 1200 block?

Answer: 1200–1299

City addressing systems define each block by the hundreds, so the 1200 block contains addresses from 1200 to 1299.

Two routes connect headquarters to a hospital: Route A is 12 miles, Route B is 9 miles. Which route is shorter in distance?

Answer: Route B

Route B is 9 miles compared to Route A's 12 miles, making Route B the shorter distance.

A city block is rectangular: 400 feet long (east-west) and 200 feet wide (north-south). An officer runs around the entire perimeter. How far does the officer run?

Answer: 1,200 feet

Perimeter = 2 × (400 + 200) = 2 × 600 = 1,200 feet.

A dispatcher tells an officer the incident is at the 'third house on the left' after turning onto Maple Drive heading north. The officer is traveling north. Which side of the street is 'left'?

Answer: West side

When traveling north, your left hand points west, so the left side of the street is the west side.

A search grid is oriented with north at the top. Teams are assigned to work from east to west. In what direction are they moving across the map?

Answer: From right to left

With north at the top, east is on the right side of the map, so moving east to west means moving from right to left.

An officer's map shows a suspect's last known location is equidistant from three precinct stations. This spatial information is most useful for:

Answer: Determining the optimal unit to respond based on travel distance

Identifying equidistant stations helps dispatchers determine which unit has the equal or shortest response distance.
