Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention without any creative labor, may be used also for those of ordinary skill in the art
To obtain other drawings based on these drawings.
Fig. 1 is a kind of river map-indication method flow chart of the invention.
Specific embodiment
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 description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
A kind of river map-indication method of the present embodiment is as shown in Figure 1, comprising:
Step S1 imports the coordinate in local river, the i.e. latitude and longitude coordinates (also referred to as GPS coordinate) in river, wherein river
Coordinate by being obtained in the system of water conservancy bureau.
Step S2, the position described point of respective coordinates, electronic map can be Amap, Baidu map on the electronic map
Or Tencent's map etc., when described point, no matter Quan Hedao described point shows section and does not show the equal described point in section.
The point retouched is carried out line to form complete river by step S3.
The river map-indication method of the present embodiment is by by the coordinate in local river described point and company on the electronic map
Line, to realize the complete display in river on electronic map.
In the present embodiment, step S2 includes: the described point API for calling electronic map, on the electronic map respective coordinates position
Graphical pointv, and show.Such as: Amap, described point API are AMap.Polyline.
In the present embodiment, step S3 includes: the setting-out API for calling electronic map, is connected between adjacent two o'clock in step s 2
Line, and show.Such as: Amap, setting-out API is also AMap.Polyline.
In the present embodiment, before step S2 further include: create transparent figure layer on the electronic map, in step S2 and S3,
Described point and line in transparent figure layer, i.e., show entire river completely in transparent figure layer, by showing and closing transparent figure layer, comes
The flexibly display in control river, nor need to modify to former map code.Specifically, such as: use Amap
When, the setting-out API of Amap is directly utilized, then before described point and setting-out, can be created in the figure layer of Amap automatically
Transparent figure layer.
Further include step S4 after step S3: according to the water quality of different sections, different colours being shown to different sections, such as:
The preferable section of water quality is displayed in blue, and is secondly shown yellow, is displayed in red again, worst display purple, so as to more intuitively
The water quality from electronic map.Section is several paragraphs that river marks off, the corresponding one group of coordinate in each section.
Step S4 includes:
Step S41, acquires the water quality data for the water monitoring device being arranged on river in real time, while obtaining water quality monitoring
The coordinate of device, water monitoring device can return in real time water quality data by wireless transport module.
Step S42 judges the section where water monitoring device.Coordinate and section pair especially by water monitoring device
The one group of coordinate pair ratio answered, if the coordinate of water monitoring device judges water quality monitoring in the range of one group of coordinate covering
Device is located at the section.
Step S43 shows the color of the corresponding setting of the water quality data on the corresponding section of electronic map.
Since water monitoring device has variety classes, for monitoring different indexs, every section has multiple and different
The water monitoring device of type can also in advance supervise water quality in order to reduce calculation amount with timely display color in step S42
It surveys device and is tied to corresponding section, i.e. water monitoring device ID and section ID opening relationships mapping table, it directly should by inquiry
Relation mapping table is to determine the section where water monitoring device.
In step S43 while display color, increases water quality data link on corresponding section, open pop-up after click
The water quality data for showing the section, is checked convenient for staff, takes control measures in time before pollution.
Further, in step S43 further include: if water quality is not up to preassigned, the chromatic flicker of corresponding section is shown
Show, and acquire the section picture storage of corresponding water monitoring device shooting, increases in corresponding section and be used to open the section
The link of picture.Such as: the water quality for defining purple colour developing section is to be not up to preassigned, then the purple flashing of corresponding section
It has been shown that, to remind staff to pay attention to.Staff can click the section of purple flashing, the section picture be opened, to see
Observe the concrete condition of the section.
The Polyline of high moral API provides click and clicks event, and high moral information window form API is used after click
(AMap.InfoWindow) pop-up shows that content, content are the hand-written backstage html+ ajax data, can by by water quality data and
Section picture is added in the ajax data of backstage, and water quality data and section picture can be shown in pop-up.
The present invention also provides a kind of river map displays, including the list for executing any of the above-described the method
