Abstract: Digital community is an important part of digital city construction. By explaining the concepts of digital city and digital community, the implementation strategy of digital community construction is discussed. The concept and significance of digital earth and digital city The construction of digital community originated in the United States. Its concept comes from \"digital city\", and \"digital city\" is an important part of \"digital earth\". With the development of space technology and remote sensing (RS), geographic information system (GIS), global positioning system (GPS) and other technologies and the implementation of major plans such as Global Earth Observation System (EOS), National Information Base Facilities (NII), and National Spatial Data Infrastructure (NSDI), the concept of \"digital earth\" was formed internationally in January 1998. The so-called \"digital earth\" is a geographic information system (GLS) described in three-dimensional language. \"Digital earth\" is a strategic thinking. Its core is to collect, process and apply information resources on the surface and shallow surface of the earth in digital form, make long-term plans, and integrate existing and developing related theories, technologies, data and applications from a systematic and holistic perspective.
