Further, it is also possible to receive, by number of ways, the data relevant to geographical position that user uploads, as received user in a certain position
Put the U.S.A uploaded shoot the video, microblogging and model, these data are generally all with the current geographic position information of user, such as longitude and latitude
Information etc..
Fig. 2 shows the stream of the geo-location service method 200 accessed according to an embodiment of the invention based on focus
Cheng Tu, the method starts from step S210.
In step S210, receive the data inquiry request relevant with geographical position of user, described data inquiry request
In include the current geographic position information of user.
Subsequently, in step S220, centered by the current geographic position of user, that the first distance arranges one for radius is circular
Region.Service based on geographical position, the data in the most neighbouring 500m are the most more meaningful, in neighbouring 500m
Special train, restaurant etc., therefore the first distance can be set as 500m, naturally it is also possible to is set to other numerical value according to practical situation.
Subsequently, in step S230, according to all geography covered in border circular areas described in geographical spatial index library searching
The unit marks of space cell.Wherein, all geographical space unit covered in border circular areas can be found in the shown institute in Fig. 3
There is tetragon cells.
Geographical space index database as above can use Google S2Library or GeoHash tool storage room, different
Be the former based on Sphere Measurement Model the latter based on areal model.As a example by Google S2Library, it is by the sphere of the earth
Being divided into little geographical space unit (Cell) according to hierarchy rules, each unit has its unique ID to number, and can be referred to as
For Cell ID.It practice, the area of each square centimeter can represent, by Cell with a unique Cell ID on the earth
ID is converted into 16 scale codings and is the unit marks (Cell Token) of this geographical space unit, with unit marks as key word
The data of coupling geographical space unit belonging to this unit marks can be searched in distributed cache or data base.Often
The size and shape of individual unit is the most incomplete same, and this generally depends on this unit position on earth.
Grade and the represented cellar area magnitude relationship thereof of geographical space unit are as shown in the table:
| Grade | Minimum area | Maximum area |
| 0 | 85,011,012km2 | 85,011,012km2 |
| 1 | 21,252,753km2 | 21,252,753km2 |
| 12 | 3.31km2 | 6.38km2 |
| 30 | 0.48cm2 | 0.93cm2 |
The unit covered required for a given shape can be calculated by Google S2Library.If setting inquiry
Near data in 500m, then we are it needs to be determined that circle centered by covering the geographical position that user is current, with 500 meters as radius
Shape region, the geographical space unit of required same levels and unit area coverage.
Fig. 3-5 respectively illustrates the 14th grade, 15 grades, the geographical space unit signal of 16 grades in Google S2Library
Figure, border circular areas therein is the regional extent covering neighbouring 500m.Inventor finds according to a large amount of actual tests, 14 grades
Geographical space unit area coverage is relatively big, the extraneous data outside causing user to obtain more 500m scope when inquiry；16 grades
Geographical space unit area coverage the most too small, then cover 500 meters border circular areas need more geographical space unit, increase
The workload of caching query.Therefore, inventor considers the unit number required for covering specific region and each unit
The region area covered, selects the geographical space unit of 15 grades to obtain preferable Consumer's Experience.
Calculate the unit marks of 15 grades of geographical units belonging to a geographical position, can call by the following method
Go out:
public String getCellToken(double longitude,double latitude){
S2Cell cell=new S2Cell (S2LatLng.fromDegrees (latitude, longitude))；
return cell.id().parent(15).toToken()；
}
As a example by Mei Tu company place longitude and latitude (24.4921434999,118.1753793695), 15 grades of its place geography
The ID of space cell is 3752794007428661248, and be converted to 16 systems obtaining unit marks Token is 34149a444, root
Mei Tu company place geography space cell can be searched in distributed cache or data base according to this unit marks
The data relevant with position.
If user video U.S. near requesting query near Mei Tu company claps, after server receives this request, the most logical
Cross Google S2Library and calculate the unit marks of all geographical space unit covered in 500 meters of this geographical position, when
So can also adjust radius size according to practical situation.Wherein, calculating and cover centered by specifying longitude and latitude, 500 meters is radius
All geographical space unit marks, can draw by the following method (Java):
In the above example, covering all geographical space unit marks of 500m border circular areas near Mei Tu company is:
"34149a40c","34149a414","34149a434","34149a43c","34149a444","
34149a44c","34149a454","34149a45c","34149a464","34149a46c","34149a474","
34149a47c ", " 34149a48c ", " 34149a4f4 ", " 34149a4fc ", " 34149a5ac ", " 34149a5b4 ", totally 17
Individual, 17 quadrilateral units shown in corresponding diagram 4 respectively.
Subsequently, in step S240, search in distributed cache using the unit marks retrieved as key word
The data of coupling, wherein the data in this distributed cache associate storage with unit marks.Specifically, distributed height
Speed caching can use Memcache memory cache system, can be concurrent by the MultiGet of Memcache when searching for data
Obtain the data in each geographical space unit stored in memory cache.
Subsequently, in step s 250, if not searching the number mated with unit marks from this distributed cache
According to, then in data base, the data of coupling are searched for using all not unit marks that the match is successful as key word.Additionally also
Can by the above-mentioned data searched in data base as key word using all not unit marks that the match is successful and
Corresponding unit marks association stores in distributed cache.
Specifically, if not setting up the subitem of certain unit marks in distributed cache, then with this unit marks for closing
The data of coupling searched in data base in keyword；I.e. to all unit marks miss in distributed cache, directly
Data are obtained from data base.Additionally, can obtain and this without reference to the querying condition of user when obtaining data from data base
All data that individual unit marks is relevant, and use the data buffer storage of WriteAnyway to write strategy in distributed cache
The unit marks of the data got from data base and correspondence thereof is associated storage.
As user needs the U.S. bat near inquiry in Mei Tu company, but in distributed cache, do not store figure institute of U.S.
" 34149a444 " unit marks and the data of correspondence.Now can be with " 34149a444 " unit marks in data base
Data corresponding to keyword search, are the most just not limited to U.S. bat class data, but all relevant to this unit marks
Data, such as the microblogging in this geographical space unit, model, special train information, restaurant etc., and all data that these are got
And " 34149a444 " unit marks of correspondence associates storage distributed telling in caching.
Data base as above can use MongoDB data base, for when caching penetrates from MongoDB data base
Accurately read the data in a geographical space unit, use the summit longitude and latitude first calculating this unit, then in MongoDB
Perform polygon inquiry to realize.
Specifically, geographical space unit summit (Java) can be calculated by the following method:
The incoming summit by Google S2Library calculated geographical space unit in<coordinates>
Longitude and latitude data.
Subsequently, in step S260, will be from distributed cache according to the condition comprised in the inquiry request of user
The data searched and the data searched from data base merge successively, filter and sequence process.
Subsequently, in step S270, return the Query Result of the data after comprising process to user.Specifically, Ke Yixian
Judge whether above-mentioned data total amount after treatment reaches the first numerical value, such as whether full one page can be taken.If then directly to
User returns Query Result；Outside all geographical space unit covered in otherwise continuing to search for border circular areas in data base
Data, until data total amount reaches the first numerical value, and return the inquiry knot including the data meeting the first numerical value to user
Really.Here, because priority treatment is the data in the range of 500m, the follow-up data supplemented from 500m scope can be straight
It is connected on after being attached to legacy data and returns to user, naturally it is also possible to these data supplemented are carried out certain filtration and sequence
Process, the invention is not limited in this regard.
MongoDB data base can read 500 meters by following query grammar outside data:
Wherein,<point coordinates>middle appointment user current location,<minDistance>middle specify minimum away from
From, be set as 500 outside 500 meters during inquiry first, non-when inquiring about first<minDistance>value be set as in upper page result
Little value.
It should be noted that in some cases user can directly set require to look up in neighbouring certain distance data,
Such as 1km, 2km or 5km etc., now for reducing inquiry workload, the data for 500m can use such scheme, outside 500m
Data then can directly go to search in data base, and the data that these two parts get the most at last return to after merging process use
Family.
Fig. 6 shows the flow chart of geo-location service method 600 in accordance with another embodiment of the present invention, and the method begins
In step S610.
In step S610, receive the data write request relevant with geographical position of user, described data write request
In include the current geographic position information of user and data to be written.Upload as a example by neighbouring U.S. bat by user, Yong Hushang
Pass while U.S.A shoots the video, the longitude and latitude that the geographical location information i.e. user of user is currently located can be brought, server need by
Positional information and this U.S.A shoot the video and are written in distributed cache and data base for inquiry.
Subsequently, in step S620, according to the geography belonging to the current geographic position of geographical spatial index library searching user
The unit marks of space cell, concrete search method describes in detail in step S230.
Subsequently, in step S630, the data being written into send and carry out transfer process to message queue.Specifically,
The data being written into send to message queue, and multiple queue handler read message from message queue and process.
Subsequently, in step S640, it is judged that whether distributed cache has stored described according to data write request
The unit marks retrieved, if be then simultaneously sent to data base by above-mentioned data after transfer processes in step S650
Store with in distributed cache；Otherwise then it is only sent to data base stores in step S660.I.e. use
The data buffer storage of WriteIfExisted writes strategy, when writing data in distributed cache, if uncached in Huan Cun
Current unit marks, the data write caching will newly do not submitted to, avoid storage in distributed cache a large amount of with this
Cold data (data that user did not the most inquire about) committed memory；Cache also can arrange certain expired time, too
The most it is accessed to be fallen clearly from cache.Wherein, when data are stored in distributed cache, can be first
Take out former data, and laggard row storage of the data newly submitted to change merging being entered.
