[Abstract]:Geographical information service is produced under the background of the rapid development of geographic information system and Internet technology. It can provide real-time and rich location information related services for Internet users. The public geographic information service system is the product of the socialized development of the geographical information service. It faces the public and provides rich and colorful geographic information service to the public in a professional, flexible and diverse way. At present, many departments have tried to apply public geographic information service to practice and achieved good results. The most important thing in GIS is geographic information data. The data sharing format is not uniform and it is difficult to update in real time when there are some problems in public GIS. This is also an important reason that restricts the development of public GIS. The purpose of this paper is to try to find a more suitable solution for public GIS. Based on the development of Tian map service, this paper designs and implements a public geographic information service system taking Weifang City as an example, using its free API and its characteristics of openness, ease of use, sharing and high resolution image. At the same time, considering the practicability of 3D GIS, the design of public system is based on the technology of integration of two and three dimensions, and the system needs analysis, architecture design, detailed design, coding and operation are completed. Based on the sky map, the system meets the basic needs and technical requirements of the public geographic information service. It realizes the integration of geographic information of urban public transport, driving, and points of interest, provides a variety of information query methods, and realizes information query and sharing on a map.
