A synchronous updating method of matching coordinates based on object binding

Abstract

The invention provides a synchronous updating method of matching coordinates based on object binding, comprising the following steps: searching address record ID of a standard address library according to the target address of a target object set; matching spatial coordinate information corresponding to the retrieved address record ID with the target object; The address record ID associated with the matching space coordinate information in the standard address library, and the association relationship between the address record ID and the matching space coordinate information and the target object ID are bound; Looks up the address record ID associated with the updated spatial coordinate information in the standard address library, An address record ID matched with the updated address record ID in the target object is retrieved, and the spatial coordinate information corresponding to the target address in the target object set to be updated is updated according to the spatial coordinate information associated with the updated address record ID and the association relationship. The invention only updates the target object set to be updated, improves the updating efficiency and realizes accurate spatial coordinate matching.

Description

technical field [0001] The invention relates to the technical field of address matching, in particular to a method for synchronously updating matching coordinates based on object binding. Background technique [0002] Address matching can be used to solve problems where sets of objects (usually represented as relational tables) need to be viewed on a map or used for spatially correlated analysis and processing. But the object set itself has no spatial coordinates, only attributes for expressing addresses. The address information in the address attribute of the object set is associated with the spatial coordinates by means of address matching. The existing address matching method needs to establish a standard address library in advance, and each record in the standard address library contains address information and spatial coordinate information. Then, the computer software program automatically performs the matching operation. In the process of address matching, the targe...

However, this matching method cannot guarantee 100% accurate matching. Generally, the matching results need to be further manually corrected, and the corrected coordinates are used as the final spatial coordinates of the target object.

[0003] In the prior art, when the spatial coordinates of some address records in the standard address library are updated, a complete match needs to be performed on the relevant data in the target object set, and the following problems exist: for the target object set, it is generally difficult to accurately Knowing which objects will be affected, you can only update the entire target object set, not just the affected objects, resulting in a large number of unnecessary update operations; each update needs to be checked and corrected, this kind of Verification and correction are usually done manually, but cannot be done automatically, which reduces the efficiency of updates
