Wireless communications and mobile computing are listed as one of the key technologies of the 21st century. The increasing popularity of mobile devices such as mobile phones and people’s unremitting pursuit of portability and convenience have driven the application of GIS on mobile devices, that is, the rapid development of mobile GIS.

Mobile GIS is an important research content of WebGIS. In the mid-1990s, mobile GIS was just born to meet the needs of field surveying and surveys, and these early mobile GISs were mainly used offline. With the development of mobile communication technology, especially the construction of 3G and 4G networks, mobile GIS quickly connected to the Web and became an important client of WebGIS. Mobile GIS connected to the Web can call the map and analysis functions in the GIS server, and can also update the data collected outdoors to the geographical database on the Web server side in a timely manner.

In addition to professional fields, mobile GIS is also widely used in public life. Applications such as mobile maps can determine a user’s location and provide location-based services (LBS) that allow users to easily query surrounding business outlets, events and friends, helping them successfully find the place to go. Looking to the future, mobile GIS can allow anyone, anytime, and anywhere to use GIS to solve any location-related problem.
