What makes a map accurate?

Every map has some sort of distortion. The larger the area covered by a map, the greater the distortion. Features such as size, shape, distance, or scale can be measured accurately on Earth, but once projected on a flat surface only some, not all, of these qualities can be accurately represented.

Are maps always accurate?

A Representation, Not a Mirror The fact that maps distort reality cannot be denied. It is absolutely impossible to depict a round earth on a flat surface without sacrificing at least some accuracy. In fact, a map can only be accurate in one of four domains: shape, area, distance, or direction.

Why is it important to know the scale of a map?

Scale on a map is important in order to give the map reader a sense of size. That’s information you need in order to interpret a distance you see (say, about a centimeter on the map) to the distance is represents (about 25,000 cm, or 1/4 km in real life, if the map scale is 1:25,000).

What does 1 250000 mean on a map?

For example, your map has a scale of 1:25 000, which means that every 1cm on the map represents 25 000 of those same units of measurement on the ground (for example, 25 000cm = 250 metres).
