Embodiment 1

[0030] like figure 1 As shown, it is a flowchart of a geocoding method provided by an embodiment of the present invention, and the method includes steps 101 to 106:

[0031] Step 101: Perform word segmentation on the geographic address to be matched.

[0032] Step 102 : for each word segment, match the word segment with the pre-stored word segment in the preset door address database to obtain at least one pre-stored word segment matching the word segment.

[0033] Step 103: According to the spatial position information in the attribute information of the pre-stored word segments, the pre-stored word segments whose spatial distance is smaller than the preset first distance threshold are aggregated into the same cluster set.

[0034] Step 104: For each word segment, from each cluster set corresponding to the word segment, select a pre-stored word segment that is closest to the geometric center of the pre-stored word segment in the cluster set as an available pre-stored word seg...

Abstract

The present invention discloses a geocoding method and apparatus. The method comprises: performing word segmentation on a to-be-matched geographical address; for each word segment, obtaining, from a preset door address library, a pre-stored word segment matching the word segment; aggregating prestored word segments whose spatial distance is less than a preset first distance threshold into a same aggregation set according to spatial location information in attribute information of the prestored word segments; selecting one prestored word segment from each aggregation set corresponding to each word segment as an available prestored word segment of the word segment; and combining the available prestored word segments according to a word order of word segments, corresponding to the available prestored word segments, in a to-be-matched geographical location, generating to-be-matched results of the to-be-matched geographical address, and selecting one to-be-matched result from the to-be-matched results as a final matching result and performing geocoding to obtain a geocoding result. According to the geocoding method and apparatus disclosed by the present invention, automatic geocoding is achieved, no manual intervention is required, and processing efficiency and matching efficiency of geocoding are improved.

Description

technical field [0001] The invention relates to the field of geographic information systems, in particular to a geographic coding method and device. Background technique [0002] In the field of electronic maps, the geographic address to be matched input by the user is converted into a geographic location through geocoding, so that the geographic address to be matched can be displayed on the electronic map, and the user can know the geographic location of the geographic address to be matched. [0003] At present, the specific implementation of geocoding is as follows: first, segment the geographical address to be matched entered by the user; secondly, for each segment, match the segment with the pre-stored segment in the preset door address database, and obtain the corresponding segment Match at least one pre-stored participle; secondly, according to the word order of each participle in the geographic address to be matched, combine the pre-stored participle corresponding to ...
