As a "bridge" connecting the information of various fields, such as politics, economy, society and culture, address is of significance in the exchange of multi-source information under the environment of big data. To solve the existing problems of address coding, such as the lack of location information, the coarse grain size, and the poor stability and readability, this paper proposes three principles for the design of new address coding models, including the independence and stability, the simplicity of realization, and the decipherability. Then, a multi-scale spatial location coding model for address is created, which is realized based on the global subdivision theory. This model takes the global subdivision grid as the basic unit, and builds the mapping rules from the address’s location to a set of grids. Furthermore, the structure of the spatial location code is provided in details. The spatial location code is developed by giving a unique sign to each of the address subdivision grid, which is the deformation of the global subdivision grid. It is described by a one-dimensional and fixed-length array, which is composed by the following four elements: the first one is C0, which is named as the Location Code; the second one is L, which is named as the Level Code, and two half span codes are the last elements. The deciphering method of the spatial location code is analyzed based on three aspects: location, region and relation. It shows that the spatial location coding model for address has presented good independence, stability, readability and scalability. Finally, this paper discusses the applications and prospects of the spatial location coding model for address, by taking the logistics industry as an example. Generally, the proposed model has presented strong theoretical and practical values for the construction of smart city.
