Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes.
Terminal of the present invention may include smart mobile phone (such as Android phone, iOS mobile phones), PC, tablet electricity
Brain, palm PC, mobile internet device (MID, Mobile Intemet Devices) or wearable intelligent equipment etc..
It is the flow of method that a kind of hand-drawing map of embodiment 1 provided by the invention is overlapped with electronic map referring to Fig. 1
Figure.This method comprises the following steps：
Step S1：Typing hand-drawing map simultaneously sets hand-drawing map level.
In the present embodiment, by hand-drawing map typing server background, terminal is with calling the Freehandhand-drawing for having set map level
Figure, to determine that hand-drawing map loads the magnification level for being.
Step S2：The latitude and longitude information of the actual geographic coordinate on several vertex of hand-drawing map described in typing；
In this step, server background typing latitude and longitude information is to calculate to be equipped with electronic third-party map for convenience
Terminal screen on hand-drawing map apply display regional location.Wherein, electronic third-party map is by taking Amap as an example.This
Embodiment hand-drawing map is rectangular, the latitude and longitude information (Lng3, Lat3) of the actual geographic coordinate on 4 vertex of typing,
(Lng3, Lat4), (Lng4, Lat4), (Lng4, Lat3).
Step S3：Position of the hand-drawing map in electronic third-party map area is determined by the latitude and longitude information
It sets, loads the hand-drawing map and be shown on the electronic third-party map layer.
In this step, terminal application software initialization obtains the relevant information (figure of the hand-drawing map of server background typing
Piece, level size, coordinate position), when hand-drawing map level is shown most more than the electronic third-party map external call
Big level sets hand-drawing map level as maximum level.
According to the horizontal axis coordinate (x1, y1) of machine screen known to hand, (x1, y2), (x2, y1), (x2, y2), mobile phone screen pair
The latitude and longitude information (Lng1, Lat1) for the actual geographic coordinate answered, (Lng1, Lat2), (Lng2, Lat2), (Lng2, Lat1)；
And the latitude and longitude information (Lng3, Lat3) of 4 vertex actual geographic coordinates of typing hand-drawing map, (Lng3, Lat4),
(Lng4, Lat4), (Lng4, Lat3).Terminal screen shows that the position of the rectangular area of the hand-drawing map is
Wherein, x1, x2 represent the terminal screen horizontal axis coordinate, and x3, x4 represent hand-drawing map on the terminal screen
Horizontal axis coordinate, y1, y2 represent the terminal screen ordinate of orthogonal axes, and y3, y4 represent the longitudinal axis of hand-drawing map on the terminal screen
Coordinate, Lng1, Lng2 represent the practical longitude of the corresponding map of x1, x2, and it is practical that Lng3, Lng4 represent the corresponding map of x3, x4
Longitude, Lat1, Lat2 represent the practical latitude value of the corresponding map of y1, y2, and it is real that Lat3, Lat4 represent the corresponding map of y3, y4
Border latitude value.
To calculate obtain (x3, x3), (x3, x4), (x4, x4), (x4, x3) so that it is determined that hand-drawing map in terminal screen
On display location region.Recycle 4 vertex actual geographic coordinates of the hand-drawing map latitude and longitude information (Lng3,
Lat3), (Lng3, Lat4), (Lng4, Lat4), (Lng4, Lat3) confirm the position that hand-drawing map should be shown in Amap
It sets.
Hand-drawing map is loaded and includes overlapping the on electronic third-party map layer to reach hand-drawing map covering
The effect of tripartite's electronic map is compensated for when the white disadvantage of space-time, refinement are shown the amplification of electronic third-party map to a certain extent
Scenic spot static state sight spot information gives tourist's offer and more specifically navigates.
Step S4：Using GPS gathers location data, the target icon is shown in the electronic third-party map, by institute
It states the target icon top set to be shown on the hand-drawing map figure layer, to realize hand-drawing map real-time display user current location
Multidate information.
In this step, the position mark point (x of the target iconm, ym) be located in the position shown in terminal screen and be
(Lngm, Latm) is the position mark point (x of the target iconm, ym), the actual geographic coordinate positioned by GPS gathers
Latitude and longitude value.
Referring to Fig. 2, method that the present invention is overlapped by a kind of hand-drawing map of a specific embodiment 2 with electronic map
Flow chart.Terminal is by taking mobile phone as an example in this method, and electronic third-party map is by taking Amap as an example.This method includes following step
Suddenly：
Step 101, Internet Server backstage hand-drawing map typing.
Step 102, the initial hierarchical arrangement of hand-drawing map.
Step 103, the longitude and latitude typing of four vertex actual geographic coordinates of rectangle hand-drawing map.
Step 104, application program of mobile phone initializes.
Step 105, the hand-drawing map for transferring Internet Server backstage, judges whether hand-drawing map level is more than 17, if
It is jump procedure 106, otherwise, jump procedure 107.
Step 106, hand-drawing map level is set as 17.
Step 107, Amap is loaded with the practical map layer grade of hand-drawing map.
Step 108, confirm hand-drawing map in high moral using the longitude and latitude of four vertex actual geographic coordinates of hand-drawing map
Position in figure.
In this step, application program of mobile phone passes through four vertex actual geographic coordinates of Amap API Calls hand-drawing map
Longitude and latitude (Lng3, Lat3), (Lng3, Lat4), (Lng4, Lat4), (Lng4, Lat3).According to the cross of machine screen known to hand
Axial coordinate (x1, y1), (x1, y2), (x2, y1), (x2, y2), the latitude and longitude information of the corresponding actual geographic coordinate of mobile phone screen
(Lng1, Lat1), (Lng1, Lat2), (Lng2, Lat2), (Lng2, Lat1)；And 4 vertex realities of typing hand-drawing map
The latitude and longitude information (Lng3, Lat3) of border geographical coordinate, (Lng3, Lat4), (Lng4, Lat4), (Lng4, Lat3).Mobile phone is answered
Rectangular area position with the display hand-drawing map is
Wherein, x1, x2 represent mobile phone screen horizontal axis coordinate, and x3, x4 represent the horizontal axis coordinate of hand-drawing map on mobile phone screen,
Y1, y2 represent mobile phone screen ordinate of orthogonal axes, and y3, y4 represent the ordinate of orthogonal axes of hand-drawing map on mobile phone screen, and Lng1, Lng2 are represented
The practical longitude of the corresponding Amap of x1, x2, Lng3, Lng4 represent the practical longitude of the corresponding Amap of x3, x4,
Lat1, Lat2 represent the practical latitude value of the corresponding Amap of y1, y2, and it is real that Lat3, Lat4 represent the corresponding Amap of y3, y4
Border latitude value.
To calculate obtain (x3, x3), (x3, x4), (x4, x4), (x4, x3) so that it is determined that hand-drawing map in mobile phone screen
On display location region.Recycle 4 vertex actual geographic coordinates of the hand-drawing map latitude and longitude information (Lng3,
Lat3), (Lng3, Lat4), (Lng4, Lat4), (Lng4, Lat3) confirm the position that hand-drawing map should be shown in Amap
Set region.
Step 109, hand-drawing map is loaded onto on the Amap in determining region.
Hand-drawing map is loaded and includes overlapping Amap on Amap figure layer to reach hand-drawing map covering
Effect, compensate for when the Amap amplification white disadvantage of space-time to a certain extent, refinement shows scenic spot static state sight spot information, gives
It is provided with tourist and is more specifically navigated.
Step 110, position mark point of the position location in Amap is shown according to cellphone GPS signal, and by position
Mark point top set.
In this step, the position mark point (x of the target iconm, ym) be located in the position shown in mobile phone screen and be
(Lngm, Latm) is the position mark point (x of the target iconm, ym), the actual geographic coordinate positioned by GPS gathers
Latitude and longitude value.
