Abstract In order to deal with the multi-source and multi-scale spatial data content integration and ensure the plotting correctness of the content, the authors have handled the multi-dynamic plotting information in which there exist such cases as the plotting marked with the same thing, different standards for foreign body, synonymous standard, and the same standard for the foreign body. The key problem is to analyze the characteristics of plotting information for themselves, perform source data analysis, extraction and conversion, and build data integration standards and quality control system. In addition, the authors have broken through the restriction that data are always from different sources or with outlines. As a result, the authors have achieved the application-oriented multi-scale spatial data integration.
