Embodiment Construction

[0072] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as recited in the appended claims.

[0073] First, the terms involved in this application are explained:

[0074] Point of Interest (POI): In the map data, a POI can be, for example, a house, a shop, the door of a community, or a bus stop. For example, the location data of the POI included in the map data may include at least four pieces of basic information: name, address, category, and latitude and longitude coordinates.

Abstract

The invention provides a map data processing and position marking method and device, equipment and a medium. The map data processing method comprises the steps of obtaining first position data of an AOI in map data; according to the first position data of the AOI, extending the boundary of the AOI to obtain second position data of the AOI; the second position data is used for determining whether a target position is located near the AOI; and storing the second position data in the map data. Therefore, whether the target position is near a certain AOI or not can be accurately judged subsequently based on the first position data representing the actual range of the AOI area in the map data and the second position data representing the expanded range of the AOI area, and the accuracy and efficiency of judging whether the target position is near a certain AOI or not are improved.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular, to a map data processing and location marking method, device, device, and medium. Background technique [0002] In real life, there will be a large number of reported events, and these reported events may be, for example, traffic congestion, accidents, and the like. At present, for the target location where the event occurs, even if the address is standardized, it is only described for the latitude and longitude of the target location, and there is a lack of supplementary information for the situation around the target location. However, the conditions surrounding the target location can affect the processing decisions for reported events. [0003] For example, when the reported event is traffic congestion, if the traffic congestion occurs on the surrounding roads of the venue where a major event is being held, if the evacuation process is not carried out in ...
