Embodiment Construction

[0025] Address positioning methods based on spatial interpolation, such as figure 1 shown, including the following steps:

[0026] 1) Fuzzy address matching: Fuzzy matching addresses in the address database that are adjacent to the undetermined address. The undetermined address is a certain house number. At least one address adjacent to the undetermined address is fuzzy matched in the address database, and the result is used for spatial interpolation;

[0027] 2) Spatial interpolation: According to the combination of adjacent addresses and the geographic entities of the existing spatial database, the coordinates of the points to be determined are interpolated.

[0028] This method is suitable for addresses that cannot be accurately matched in the address database with the same semantics as the undetermined address, provided that the urban topographic element information in the spatial database is complete.

[0029] Fuzzy address matching includes fuzzy matching of at least on...

Abstract

The invention provides an address locating method based on space interpolation. The method comprises the following steps of firstly, fuzzy address matching: fuzzily matching an address in an address database, which is adjacent with an address to be determined; and then, space interpolation: according to the combining of the adjacent address and a geological entity of the existing space database, interpolating coordinates of a point to be determined. When no address which has the same semantic meaning as the address to be determined in the address database can be matched, the adjacent address is obtained, and the coordinates of the address to be determined are interpolated according to space coordinates of the adjacent address and the distribution conditions of the existing space database. Under the condition of incompleteness of the address database, through combing with the space interpolation method of the existing space entity, the matching result of the data is improved, the accuracy of the address locating is improved, and the manual collecting cost is reduced.

Description

technical field [0001] The invention relates to an address positioning method, in particular to an address positioning method based on space interpolation. Background technique [0002] In e-government applications, there are a lot of address data, such as population, enterprises, real estate and other government affairs data. Most of these address data are described in natural language. It is necessary to convert text addresses into spatial geographic coordinates to realize the integration of non-spatial data and spatial data. Integration and sharing. Due to the differences between Chinese and English addresses, address positioning usually adopts steps such as address standardization, address word segmentation, and address matching. [0003] However, in the address matching process, due to the difficulty of completely covering the address library information, the address matching failure often occurs. At this time, it is necessary to perform spatial interpolation on adjac...
