Numerator on an RF must always be at number?

Answer 27

One Ex: 1:25,000

Answer 30

Large scale or small scale

Question 31

Example of smaller map enlarge map scale

Answer 31

Smaller scale map , less detail ex. 1:25,000,00 Larger scale map, more detail ex. 1/10,000

North and south vertical lines. Angular measurement of a location east or west of the prime meridian. Run in the north to south direction from the two poles but measured in a west or easterly direction from the prime meridian.

Question 34

Large scale

Answer 34

Cover small areas with greater detail: good for doing detailed planning
