Method, device, server and storage medium for determining regional changes

Abstract

The embodiment of the present application provides a method, device, server, and storage medium for determining regional changes. This application preliminarily uses the change characteristics of the sample geographical area as a training sample, and uses the change labeling results of the sample geographical area as sample labels to train to obtain a change determination model. , and then for the geographical area to be measured, obtain the change characteristics that can reflect its change over time, input the change characteristics into the change judgment model, and obtain the judgment result of whether the change occurs in the geographical area to be measured output by the model. With the help of the pre-trained transaction judgment model, the application judges the transaction from the perspective of the geographical area, rather than targeting a single point of interest POI, so as to realize the judgment of the transaction of the entire geographical area to be tested, and there will be no omission of a single POI transaction. This makes the judgment of the change more comprehensive, and the update of the map is also more comprehensive, ensuring the current situation of the map.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a method, device, server and storage medium for determining a regional transaction. Background technique [0002] Current status means that the geospatial information provided by the map should reflect the latest current situation as much as possible. To put it simply, current status refers to the extent to which the map reflects the status quo of geographic information. [0003] Under the new situation of rapid urban development, urban topography, landforms, and features change very frequently. In order to ensure the current situation of the map and reflect the actual changes of human and natural elements in a timely manner, the geographical elements that have changed in the geographical area must be revised or surveyed according to different situations and in accordance with unified technical requirements on the map that has been measured. Retest. [00...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, users generally report the change information of geographical elements, but this method is prone to under-reporting. For example, when a certain shopping mall is demolished as a whole, users may only report POIs (English: Point of Interest, Chinese : Points of interest) changes were reported, but changes of less popular POIs were not reported, resulting in incomplete map updates
