Understanding 6-Figure Grid References

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

• To measure the height of mountains

• To find a location on a local scale

• To determine the depth of rivers

• To calculate the distance between cities

How do eastings and northings differ from latitude and longitude?

• Latitude is read first in eastings and northings

• Eastings and northings are read in the same order as latitude and longitude

• Longitude is read first in eastings and northings

• Eastings are read first, unlike latitude and longitude

If a point is halfway along a grid square, what would the third digit of its easting be?

• 5

• 0

• 7

• 9

What is the six-figure grid reference for point A if its easting is 970 and northing is 280?

• 970028

• 970280

• 280970

• 028970

For point B, if the easting is 989 and the northing is 319, what is the six-figure grid reference?

• 031989

• 989031

• 319989

• 989319

In the worked example, what is the easting for the surf club if it is halfway across the grid square?

• 770

• 775

• 780

• 785

What is the northing for the surf club if it is nine tenths up the grid square?

• 970

• 969

• 965

• 960

What is the six-figure grid reference for the surf club?

• 775096

• 969775

• 096775

• 775969

For the Kaiapoi River's entry point, what is the easting if it is one tenth along the grid square?

• 753

• 750

• 751

• 752

What is the full six-figure grid reference for the Kaiapoi River's entry point?

• 095751

• 751095

• 751958

• 958751
