A Multi-Source Heterogeneous Vector Space Data Integration Scheme Based on GeoJSON

Abstract

With continuous innovation of the “Internet+” and development of related industries, huge amounts of data need to be integrated on the basis of spatial data analysis and processing. Therefore, efficient integration of multi-source heterogeneous spatial data and data interoperability requirements has become more and more urgent. The design of a multisource heterogeneous vector spatial data integration scheme on WebGIS has been proposed by GeoJSON as the universal transformation format, based on the analysis of the existing multi-source heterogeneous spatial data conversion method. Finally, a prototype of the online prototype system was developed with. Net platform to verify the feasibility and practicability of the scheme. The scheme has the characteristics of high efficiency, easy to expand and low cost, and provides a new way to realize the data integration of “Internet+”.
