An Offline Geocoding Unstructured Address Resolution System

Abstract

The invention provides an off-line geocoding unstructured address analysis system, which is characterized in that it includes: a local POI coordinate library establishment module; an unstructured address geocoding analysis module; and an associated traffic object module. The invention has the advantages that the off-line geocoding using the address coordinates of the local database does not depend on the remote interface of the Internet, the speed is fast, and it supports the geocoding address resolution of unstructured addresses, and is suitable for large batches of unstructured address resolutions. The analyzed geographic location points are associated with traffic objects, and the joint description of coordinate points and traffic objects lays the foundation for later data mining analysis.

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
