Understanding 6-Figure Grid References

What is the primary purpose of grid references on a topographic map?

• To determine the weather conditions

• To measure the height of mountains

• To find a location on a local scale

• To calculate the distance between two points

What are the vertical lines on a topographic map called?

• Northings

• Longitudes

• Eastings

• Latitudes

In which order should you read the grid reference numbers?

• Latitude first, then Longitude

• Longitude first, then Latitude

• Easting first, then Northing

• Northing first, then Easting

What is the grid reference for point A on the simple map?

• 975280

• 975290

• 970290

• 970280

How is the grid reference for point B determined?

• By reading the easting first

• By using a compass

• By estimating the distance from the center

• By reading the northing first

What is the grid reference for point C on the simple map?

• 005255

• 005250
