Design and Implementation of Online Mapping System Based on the Web Geo-data
With the development of information technology, mobile Internet, cloud computing and other technologies have deeply af-fected all aspects of society and the huge amount of data produced by human activities. These data not only have a richer data source, but also have the spatial and temporal attributes and contains the enormous development potential and application value. Aiming at the problems of inconsistent data standards and heterogeneous classification systems under different application situations, this paper ob-tains various types of open-sourced data from internet, uses the technology of web crawler and automatic processing to automatic pro-cessing and databasing of the Crowd Sourcing Geographic Data, and realizes its databasing and updating. It uses Crowd Sourcing Geo-graphic Data fusion technology, designs the system by using scientific technical framework, adopts modular construction idea, realizes the design, development and application of the online mapping system and achieves good application results.
