A map doesn't tell you which way is north, it tells you which direction to go to get somewhere assuming you already KNOW which way is north... so it's not really an option except in special cases (for example, if a map shows two landmarks that are visible from the sailor's current position, he can use that to determine both where he is on the map and which direction is north).

How can people tell time by looking at Polaris?

People can tell time by looking at Polaris, or the North Star, because it is positioned nearly directly above the North Pole, making it a reliable indicator of true north. By observing the angle of Polaris above the horizon, one can determine their latitude. Additionally, the stars around Polaris move in a predictable manner throughout the night, allowing for an understanding of the time based on their position. However, this method is more effective for navigation than for precise timekeeping.

The altitude of polaris indicate that my location on the map but?

The altitude of Polaris, or its angle above the horizon, corresponds to your latitude in the Northern Hemisphere. For example, if Polaris is observed at an altitude of 30 degrees, you are located at approximately 30 degrees north latitude. This relationship allows navigators and astronomers to determine their geographic position using the stars. However, it is important to note that this method is applicable only in the Northern Hemisphere, as Polaris is not visible from the Southern Hemisphere.
