How Do I Choose?

As a map user, knowing all that you now know about map projections, how do you choose the right projection? You must ask yourself questions about what you are using the map for. Are you calculating the distance from your school to a school in a sister city in Japan? Then you will probably choose an equidistant map projection because it shows distance correctly.

Do you want to study how much land is used for growing crops in India compared to Australia? Then you will want to ensure that the area of these countries is correctly represented and would be a good choice.

Maybe you are just using a map to show where your country is on a map. In this case, making sure that the shape of the country is correct and that it conforms to the shape represented on a globe is important and would be best for your purpose. It is important to remember that whenever you choose to keep a true representation of one characteristic, either shape, areas, distance, or direction, another characteristic is changed or distorted. Only on a globe, which is spherical like the Earth, can all these characteristics be correctly represented.
