Embodiment 1

[0036] According to an embodiment of the present invention, a method embodiment of a method for determining a geographical location name is provided. It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions , and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0037] figure 1 is a method for determining a geographic location name according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0038] Step S102, acquiring the location information of the target terminal to be queried.

[0039] Wherein, the target terminal in this embodiment may be a vehicle-mounted terminal, or may be a mobile terminal capable of GPS positioning, which is not limited in this embodiment. The targe...

Embodiment 2

[0065] According to an embodiment of the present invention, an embodiment of an apparatus for implementing the foregoing method embodiments is also provided, and the apparatus provided by the foregoing embodiments of the present application can run on a computer terminal.

[0066] figure 2 is a schematic structural diagram of an apparatus for determining a geographic location name according to an embodiment of the present application.

[0067] like figure 2 As shown, the device for determining the geographical location name may include a first acquiring unit 202 , a judging unit 204 and a determining unit 206 .

[0068] Wherein, the first obtaining unit 202 is used to obtain the location information to be queried of the target terminal; the judging unit 204 is used to judge whether the spatial distance between the location information to be queried and the reference location information is less than or equal to a preset threshold; the determining unit 206. If the spatial d...

Abstract

The invention discloses a method and a device for determining a geographic location name. The method comprises the steps that to-be-queried location information of a target terminal is acquired; whether the spatial distance between the to-be-queried location information and reference location information is smaller than or equal to a preset threshold value is judged; if the spatial distance between the to-be-queried location information and the reference location information is smaller than or equal to the preset threshold value, the geographic location name corresponding to the to-be-queried location information is determined as a geographic location name corresponding to the reference location information; and if the spatial distance between the to-be-queried location information and the reference location information is greater than the preset threshold value, the geographic location name corresponding to the to-be-queried location information is acquired from a network geographic information system. Through the method and the device, the technical problem that query delay is long because a geographic location name corresponding to a GPS needs to be queried continuously from the network geographic information system in the prior art is solved.

Description

technical field [0001] The invention relates to the field of location monitoring, in particular to a method and device for determining a geographical location name. Background technique [0002] With the development of positioning monitoring technology, more and more monitoring software using GPS (Global Positioning System, global satellite positioning system) technology for positioning is replaced by webGIS (web Geographic Information System, network geographic information system) to realize positioning monitoring. [0003] However, it is difficult for webGIS to display geographic location names during trajectory playback and GPS report generation, because it is necessary to continuously query the webGIS server for the geographic location names corresponding to GPS, which is limited by the performance limitations of webGIS and network query delays. For track playback of location names and GPS reports, it takes a long time to query the location name of the webGIS server in r...
