Information is the soul of the logistics, and the powerful logistics network is a prerequisite for the Fourth Party Logistics. Information network can control all aspects of the logistics supply chain, integrate the national logistics resources effectively, enhance the efficiency and reduce logistics cost. This paper proposes a logistics platform based on WebGIS/3G/GPS, which can share the attribute data and map data in high degree and realize distribute storage. It not only can change the dull attribute data into vivid graphics, but also makes the management and maintenance for massive data convenient and efficient, and control the logistics process accurately and timely. The implementation of the platform will maximize the advantages of the Fourth Logistics, strengthen control over the logistics process.
