State Trooper Map Reading and Navigation 5

Question 1

A trooper is setting up a perimeter around a 4-block area. Using map coordinates, the block corners are at A(0,0), B(4,0), C(4,4), D(0,4). Which roads form the perimeter?

Accepted Answer

The roads along all four outer edges of the 4-block square

Answer

A perimeter encompassing a rectangular block area requires officers posted along all four outer boundary roads.

Question 2

When using a GPS unit in a police vehicle, the trooper notices the device shows 'HDOP 8.' What does a high HDOP value indicate?

Accepted Answer

Poor satellite geometry, resulting in reduced position accuracy

Answer

HDOP (Horizontal Dilution of Precision) measures satellite geometry quality; a value of 8 indicates poor geometry and less accurate position data.

Question 3

A trooper needs to identify the fastest route between two points on a highway map. Which map feature provides the most useful information for this decision?

Accepted Answer

Road classification and posted speed limits shown in the legend

Answer

Road classification (interstate, US highway, state route) combined with posted speed limits tells a trooper which routes allow the highest legal speeds.

Question 4

On a map, what does a symbol of a small airplane near a labeled name typically indicate?

Accepted Answer

A public or private airport or airfield

Answer

The airplane symbol on maps universally denotes an airport or airfield, which may be relevant for emergency response coordination.

Question 5

A trooper is relaying a location to a helicopter using compass bearings and distance. The helicopter is at a fixed point; the trooper says the subject is at '270 degrees, one mile.' In which direction does the helicopter fly?

Accepted Answer

Due west, one mile

Answer

A compass bearing of 270 degrees corresponds to due west; the helicopter must fly one mile west to reach the reported location.
