The method flow diagram that Fig. 1 provides for the embodiment of the present invention, as shown in fig. 1, the method may comprise steps of:
In 101, obtain the location data of user.
Can obtain the location data of user in this step from locating module, this locating module can use such as GPS fixedThe multiple positioning modes such as position, architecture, wifi location, this is not any limitation as by the present invention, as long as getting location data?.The location data got are usually longitude and latitude data.
In 102, location data being mated in map data base, the data genaration text utilizing coupling to obtain is retouchedThe positional information stated.
Following two implementation can be included but not limited in this step:
First kind of way: determine the Fundamental Geographic Information System that location Data Matching arrives, this Fundamental Geographic Information System includes positioning numberAccording to administrative division and the road information at place, the text then generating Fundamental Geographic Information System describes.
Generally can store the longitude and latitude of each map element, administrative division and road information, example in map data baseIf certain user location obtains longitude and latitude and is: 116.306301,40.053631, through mating in map data base, can obtainThe Fundamental Geographic Information System of its correspondence is: ShangDi No.9 Street, Haidian District, BeiJing City.Certainly, the granularity of this Fundamental Geographic Information System can be flexibleSelect, can be as accurate as administrative division, it is also possible to be accurate to road, it is also possible to be accurate to guideboard number.
This mode is easier to understand, is not described in detail in this.Introduce the second way below.
The second way is the reference point neighbouring with as a reference to form text and describe, specifically can be as in Fig. 2Shown in, comprise the following steps:
In 201, the reference point in this location data preset range of matching distance in map data base.
Here reference point can be some well-known businessman, landmark, tourist attractions, means of transportation etc..ByPOI (Point of Interest, point of interest) information, these POI have all been collected in great majority in existing map data baseInformation includes the information such as title, classification, longitude and latitude, it is also possible to can comprise some and describe information.POI can include government department,Commercial undertaking, tourist attractions, means of transportation, building, etc., kiss is compared in the requirement of reference point to be determined with the present inventionClose, the POI from map data base can determine reference point the most in embodiments of the present invention.Except of course that use POI itOutward, it would however also be possible to employ other modes, for example with the businessman of mark, building, sight spot, means of transportation in map data baseDeng.
In this step, the POI in this location data preset range, such as distance can be determined in map data basePOI in the range of 100 meters, the position location of user.Then according in the distance of popularity, significance and these location data etc.A kind of or combination in any, marks to each POI determined, then selects scoring to come the POI of top n as a reference point, NFor default positive integer.
Wherein POI can be divided into various rank according to popularity in advance, and the popularity that rank is the highest is the highest, and POI commentsDivide the highest.Significance can be evaluated according to the height at this POI place, signboard size etc., the height at this POI place, trickThe information such as board size can obtain from the description information of POI.The such as depth of building of " Jinqiu International Building " is higher, because ofThis its significance is the highest, and the scoring of this POI is the highest.The most such as " Bank of China ", although its between floors layer, butOwing to its signboard is huge the most obvious, therefore its significance is the highest, and the scoring of this POI is the highest.If it addition, certain POI distanceThe position location of user is the nearest, and its scoring is the highest.When POI is specifically marked, can be right with comprehensive considering various effectsAfter the scoring of each factor is weighted processing, obtain the final scoring to POI.
In 202, these location data relative position relative to this reference point is determined.
There is a corresponding latitude and longitude information in location data in map data base, each reference point is in map data baseThere is also the latitude and longitude information of correspondence, carry out the phase that can be obtained by positioning data relative to reference point according to both longitudes and latitudesTo position.This relative position can include two parts information: positions data relative to the directional information of reference point and location numberAccording to the range information relative to reference point.Position relatively can be obtained by geometric algorithm, is not described in detail in this.
