Different types of maps have different uses. Tourist maps, for example, have signs to show places of interest in an area. When tourists read these maps, it is easy for them to find where to go and what to see in a place and it is easy for them to go and find their ways to these places.

Road maps show large areas so that people can plan long journeys. Different types of roads are given different numbers. For example, if you want to go to Wuhan, you just follow G70 Road and keep looking at the road signs.

Distribution maps(分布图) use colors or signs to show facts about an area. For example, where different languages are spoken, how many people live in an area, how cold and hot some places are, or whether rice grows in certain places.

Some maps, such as railway maps, use straight lines to show everything. This is easy for people to read. Trains are fast. People don’t have to think about small places they go past. They just need to know the two ends of their trips.
