Development Status of Modern Cartography

1, digitization: refers to the digital transformation of map drawing technology, which integrates modern surveying and mapping technologies such as sensors, unmanned aerial vehicles and satellites, and presents real scenes on the map in a digital way, greatly improving the accuracy and updating speed of map data.

2. Intelligentization: Introducing artificial intelligence, big data, cloud computing and other technologies into map drawing can automatically and intelligently process massive map data, optimize business processes such as map query and planning, and improve the efficiency of map application.

3. Visualization: refers to the visual transformation of the map. Through virtual reality, augmented reality and other technologies, the static map presentation mode is changed into a more vivid, three-dimensional and rich map presentation mode, which improves the visual experience of users and the playability of map applications.

4. Diversified application: refers to the gradual expansion of the application scope of maps, including smart cities, logistics and distribution, disaster prevention and control, tourism planning and other fields, and at the same time brings multi-perspective integration and cross-validation of map data to improve the reliability of map application.

5. Open construction: Map data can be shared and opened, and all kinds of institutions and individuals can participate in the production and maintenance of map data, which will make cartography progress and promote the continuous development of cartography. The development of modern cartography has experienced a series of major changes from manual drawing to computer drawing, from active collection to passive collection, from two-dimensional display to three-dimensional simulation. In the future, cartography will continue to develop and grow in digitalization, intelligence, visualization, diversified applications and open construction.
