CN102506878A - Method for establishing point of interest (POI) in application of location based service (LBS) - Google Patents

Abstract

A method for establishing a point of interest (POI) in the application of location based service (LBS) solves the technical problem that the geographic location of POI is difficult to determine when a user establishes the POI on an electronic map by himself. The method comprises determining the location of a to-be-established POI on the map; and recording an information set including the location information of the to-be-established POI. The location of the to-be-established POI on the map is acquired by correcting coordinate deviation based on an online electronic map by means of the geographic location of given POI at the periphery of the to-be-established POI. The invention solves the above problem by searching the POI information and positioning the peripheral POI in combination with the online map, which allows common users to rapidly and accurately establish the POI.

Description

, creates LBS the method for POI in using

Technical field

The present invention relates to a kind of method of creating POI on the internet, belong to LBS application service field, particularly a kind of in LBS uses the user can create the method for POI voluntarily fast.

Background technology

LBS is the english abbreviation of Location Based Service, i.e. location based services, and the position is most crucial basic data in LBS uses, it is the foundation stone of whole application; Generally we use POI to represent positional information, and POI is the english abbreviation of Point of Interest, i.e. point of interest, and each POI comprises cubic surface information: title, classification, longitude, latitude.

The POI forming process that LBS uses generally be on the basis of primary data the user according to individual demand; On electronic chart, create perfect voluntarily; The difficult point of user when creating POI information is how to identify longitude and the latitude of POI on the internet fast and accurately.The classic method of creating POI on the internet mainly contains two kinds:

A, provide simple list to fill in title, classification, longitude, latitude voluntarily to create by the user;

B, the warp, the latitude that on the basis of A, provide the Online Map assisted user to find POI to belong to.

The A method is owing to will fill in longitude, latitude information voluntarily, and under the situation that does not have GPS located in connection instrument and longitude and latitude data check, domestic consumer can not accomplish; The B method has solved this problem to a certain extent, provides an Online Map, on map, identifies corresponding position by the user, gets access to longitude and latitude roughly then.But the B method still exist can not or can not the accurate in locating longitude and latitude situation: first kind of situation also is modal situation; The user do not know POI to be determined go map where; Only know the title of the known POI of this POI periphery to be determined, but the particular location of this known POI on map is also unclear; Second kind of situation: the information that shows on the map all is the information of very simple summary; Be difficult to know accurately that according to these information the POI that periphery is known or the situation of buildings carry out reference, not have reference also just can't accurate in locating go out detailed coordinate position.To above-mentioned two kinds of defectives, be necessary to make the new scheme of a cover to solve the problem that is difficult to the longitude and latitude of definite this POI when the user creates POI voluntarily on electronic chart.

Summary of the invention

The present invention is for solving the technical matters that is difficult to the longitude and latitude of definite this POI when the user creates POI voluntarily on electronic chart; Designed a kind of method of in LBS uses, creating POI; Well solve these problems in conjunction with the mode of Online Map, let domestic consumer also can create POI fast and accurately through POI information searching and periphery P OI location.

The present invention for realizing the technical scheme that goal of the invention adopts is;, creates LBS the method for POI in using; Comprise in the said method confirm the position of POI yet to be built on map, and typing comprise the information intersection two big steps of the positional information of above POI yet to be built; The above-mentioned position of POI yet to be built on map be based on online electronic chart, proofread and correct by the longitude and latitude of the known POI of POI yet to be built periphery, through coordinate offset and obtain, and concrete steps comprise:

A, definite roughly POI yet to be built are in the position on the map: input composite key fast query is to the known POI information of part of POI periphery yet to be built in the search column of creating the interface; And on map, indicate the particular location of above-mentioned known POI, obtain the rough position of POI yet to be built thus;

B, find out all known POI of POI yet to be built periphery through the running fix coordinate: running fix coordinate in the zone of the known POI of above-mentioned part, the elements of a fix whenever move a position and will search algorithm all POI and information thereof that 1 ~ 5 kilometer range around it is interior through distance and on map, identify;

C, proofread and correct and the above-mentioned known POI that finds obtains the accurate longitude and latitude of POI yet to be built by coordinate offset.

Can well carry out POI on the internet through the present invention and create, solve the problem of multiple known establishment POI, the situation of known longitude and latitude directly typing longitude and latitude is created; Do not know that the position on map can navigate to the POI position of periphery fast through name lookup; Being not sure of accurately the position can constantly proofread and correct through periphery P OI location.The present invention combines Online Map well to solve these problems through the mode of POI information searching and periphery P OI location, lets domestic consumer also can create POI fast and accurately.

A, definite roughly POI yet to be built are in the position on the map: input composite key fast query is to the known POI information of part of POI periphery yet to be built in the search column of creating the interface; And on map, indicate the particular location of above-mentioned known POI, obtain the rough position of POI yet to be built thus;

B, find out all known POI of POI yet to be built periphery through the running fix coordinate: running fix coordinate in the zone of the known POI of above-mentioned part, the elements of a fix whenever move a position and will search algorithm all POI and information thereof that 1 ~ 5 kilometer range around it is interior through distance and on map, identify;

C, proofread and correct and the above-mentioned known POI that finds obtains the accurate longitude and latitude of POI yet to be built by coordinate offset.

Comprise the longitude and latitude of POI on map, better address in the above-mentioned information intersection, and create title.
