Abstract: | Abstract: To solve the problems in the establishment of city geographic information platform
including difficulty in data acquisition and high development cost, this paper introduced open source
technologies, and proposed a platform establishment method based on open source data, open source
tools and open source framework. The proposed platform consists of two parts, including the data
module and the visualization module. In order to construct the data module, the open source
geographic project open street map (OSM) was selected to obtain building and division data, and a
building merging algorithm was designed to further improve data quality. The building data was then
organized hierarchically based on administrative divisions and provided to specific applications
through the data interface constructed by ASP. NET. The visualization module was implemented
based on the open source geographic information system (GIS) project Cesium, and complete user interfaces were designed. Taking Beijing as an example, we carried out the development and testing
of the prototype system, and confirmed the feasibility of the proposed technical route. The advantages
of open source technologies were fully considered in this paper to reduce platform development costs
and promote the research and application of city geographic information platform. |
