Geographic Information Systems, or GIS, are tools that help people understand and use information about the world around them. In China, GIS are used to help people better understand the geography of the country, such as cities, rivers, mountains, and forests. GIS can also help people do things like plan out where to build roads and bridges, or where to locate power lines and communications networks. GIS can also help people in China find out things like weather forecasts, or which areas are environmentally protected zones. GIS can also be used to help people prepare for natural disasters like earthquakes or floods. By using GIS, people in China can make better decisions about how to plan their cities, when to build roads, and which areas need protection and conservation.
