Offline geocoding unstructured address resolution system

Abstract

The invention provides an offline geocoding unstructured address resolution system, which is characterized in comprising a local POI (Point Of Interest) coordinate library establishment module, an unstructured address geocoding resolution module and a related traffic object module. The system has the advantages that an Internet remote interface is not depended when the address coordinate of a local database is used for carrying out offline geocoding, speed is high, the geocoding address resolution of the unstructured address is supported, and the system is suitable for large-scale unstructuredaddress resolution. A resolved geographic position point related traffic object lays a foundation for later data mining by taking the joint description way of a coordinate point and the traffic object.

Description

technical field [0001] The invention relates to a method of geocoding unstructured address information by using address coordinates stored in a local database, converting the longitude and latitude information corresponding to the address information, and combining the longitude and latitude information of each traffic object in the map layer to associate the address information with The system related to traffic objects is applicable to the traffic information and geographic analysis service industries, and belongs to the technical field of geocoding address resolution. Background technique [0002] Geographic location coordinate information is the basis for specific analysis and statistical mining of geospatial information. People frequently use unstructured address information in their daily life, and the derivative development of any technology application needs to be based on precise geographic location coordinate information. In order to provide accurate geographic co...

Problems solved by technology

[0004] (1) The error rate is high when unstructured addresses are used for semantic recognition;

[0005] (2) The coordinates of each online map POI address library are incomplete, which makes the conversion accuracy of geocoding low;

[0006] (3) The coordinate systems of each online map are different, and the converted latitude and longitude coordinate points cannot be used uniformly;

[0007] (4) Geocode conversion can only be performed in an environment with Internet access;

[0008] (5) The interface speed of accessing remote services through the HTTP / HTTPS protocol is slow;

[0009] (6) Each online map remote service has a daily access limit, which is not suitable for large-scale geocoding;

[0010] (7) Each online map does not provide the function of linking traffic objects
