The point of interest of keyword matching.
In the embodiment of the present invention, scanned for by shape point, but based on the institute in shape point sequence
There is shape point to determine a region of search, search and each Keywords matching in a region of search
Point of interest.The trend of navigation way is embodied due to shape point sequence, therefore, based on shape point sequence
Identified point of interest search region necessarily around navigation way determined by interest point sequence, because
This, the point of interest for searching is the point of interest searched along navigation way.
In the embodiment of the present invention, along the point of interest that searching route matches by keyword search.
For example, it is assumed that the search keyword of user input is " Agricultural Bank of China " and " gas station ",
So, server is it is determined that behind point of interest search region, server searches for institute in point of interest search region
There is the point of interest of the Agricultural Bank of China, meanwhile, server searches for all oilings in point of interest search region
The point of interest stood, the point of interest of all Agricultural Bank of China that then will be searched and all gas stations it is emerging
Interest point is sent to electronic equipment.Wherein, the point of interest of the Agricultural Bank of China refers to comprising Chinese agriculture in attribute
The point of interest of industry bank identification information, similarly, the point of interest of gas station refers to know comprising gas station in attribute
The point of interest of other information.
Point of interest is reached in order to be more convenient user, the point of interest for searching can be screened, in order to
Offer more meets the point of interest of user's request.
Optionally, can be after the completion of point of interest search range searching, the direct of travel based on user, according to
Point of interest is screened according to the position relation between point of interest and navigation way, the point of interest after screening is sent to

The transmission order of shape point determines.Because travel route is departure place, destination, the warp according to user's selection
By ground, avoid etc. the bar navigation path that is calculated by corresponding navigation path planning principle, therefore,
It is known that user is from after departure place, in the process of moving by the sequencing of shape point, client
Hold during to server end transmission shape point sequence, by the elder generation of shape point during being travelled according to user
The shape point that first passes through of each shape point, i.e. user is first to service during order sends shape point sequence successively afterwards
Device send, after by shape point after to server send.Therefore, the shape that server end is first received
Point is shape point that user first passes through, and the shape point that server is received after the meeting be then after user by
Shape point.
If specifically, the direct of travel of user is first direction, the side of navigation way first can will be located at
Point of interest as target point of interest return electron equipment side client, wherein, the side of navigation way first is
Refer to first direction as prime direction, the region in the range of dextrorotation turnback.In particular,
In China, the side of navigation way first refers to right side area of the navigation way along user's direct of travel.
If positioned at the point of interest negligible amounts or not interested point of the side of navigation way first, can be from being located at
A part of point of interest is selected to be added into return electron in target point of interest in the point of interest of the side of navigation way second
The client of equipment side.Wherein, the side of navigation way second refers to the inverse time with first direction as prime direction
Region in the range of pin rotation 180 degree.In particular, in China, the side of navigation way second is to instruct

Point, for Equations of The Second Kind point of interest, can select 5 points of interest as target point of interest using every 2000 rice huller screen.
Optionally, priority can also be set between different screening rules.For example, point of interest location with
The priority of the position relation between navigation way is preferential higher than the distance of point of interest distance navigation route
Level, i.e. when target point of interest is screened, preferentially by the point of interest on the right of road as target point of interest,
If the point of interest negligible amounts on the right of road, in the point of interest on the road left side being filled into target point of interest, its
In, the point of interest near apart from road is preferentially chosen as target point of interest in the point of interest on the right of road.
