Map Boundaries and Coordinates

This video tutorial explains how to determine the latitude and longitude of map boundaries on a topographic map, specifically focusing on the Austin East area in Texas. It covers identifying the latitude of the southern and northern boundaries and the longitude of the eastern and western boundaries. The video also explains the concept of a seven and a half minute series map, which represents 7.5 minutes of latitude and longitude. By comparing the longitude of the east and west boundaries, the video demonstrates how to confirm the map's series classification.

What is the primary purpose of the video?

• To teach how to draw topographic maps

• To determine the latitude and longitude of map boundaries

• To discuss the climate of the Austin East area

• To explain the history of topographic maps

Which numbers indicate the latitude of the southern boundary?

• 97° 37 minutes 30 seconds

• 30° 22 minutes 30 seconds

• 97° 45 minutes

• 30° 15 minutes

What is the significance of the numbers being the same in both south corners?

• They show the latitude of the southern boundary

• They indicate the longitude of the map

• They are used to calculate the map's area

• They represent the map's scale

What is the longitude of the west boundary of the map?

• 30° 22 minutes 30 seconds

• 97° 45 minutes

• 30° 15 minutes

• 97° 37 minutes 30 seconds

What is the longitude of the east boundary of the map?

• 97° 45 minutes

• 30° 15 minutes

• 97° 37 minutes 30 seconds

• 30° 22 minutes 30 seconds

How is the latitude of the northern boundary identified?

• By checking the numbers in the southwest corner

• By comparing the numbers in the northeast and northwest corners

• By looking at the map's title

• By measuring the distance from the equator

What does the number 30° 22 minutes 30 seconds represent?

• Longitude of the west boundary

• Latitude of the northern boundary

• Longitude of the east boundary

• Latitude of the southern boundary

What does a seven and a half minute series map indicate?

• It is updated every 7.5 years

• It covers 7.5 degrees of latitude and longitude

• It is 7.5 times more detailed than other maps

• It represents 7.5 minutes of latitude and longitude

How can you verify the map is a seven and a half minute quadrangle map?

• By measuring the map's physical size

• By subtracting the longitude of the east boundary from the west boundary

• By comparing it to a standard map

• By checking the map's scale

How much latitude and longitude is recorded on the map?

• 45 minutes each

• 30 minutes each

• 15 minutes each

• 7.5 minutes each
