Step 12: and fusing the weather risk information with the map according to the geographical position information by calling a map engine so as to obtain the map fused with the weather risk information.
In practical application, the map engine is called, and a function interface provided by the map engine is called, and the weather risk information and the map can be fused by calling the function interface.
When the weather risk information is fused with the map, the analysis and superposition processing of the weather risk information and the map raster layer can be carried out according to the geographical position information through the spatial autocorrelation analysis technology, so that the weather risk information and the map can be fused according to the geographical position information, and the map fused with the weather risk information can be obtained.
Step 13: invoking a map engine to perform: based on a map obtained by fusing weather risk information, displaying a geographical position at a geographical position matched with geographical position information contained in the traffic management weather risk product on the map according to a product position display form corresponding to a map zoom level; and displaying the weather risk information contained in the traffic management weather risk product at the matched geographical position.
In practical applications, considering that the electronic map may have functions of zooming out and zooming in, in an embodiment of the present specification, a product location display form may be set based on a map zoom level, and specifically, the product location display form may include: at least one of a stake point and a road segment.
The stake points may be traffic data that segments a traffic line, which may include highways, such as national roads, provincial roads, and the like. The traffic data may include road stub points of the highway and administrative divisions of the highway. The stake point can be determined according to traffic data or according to the management requirement of a road traffic management department, for example, the stake point can be set to be one stake point every 1km according to the management requirement. Accordingly, the road segment may be a traffic line between pile points. It will be appreciated that the transit line between any two pile points may be a section of road.
As described above, the electronic map may have functions of zooming out and zooming in, and a product position display form may be set based on a map zoom level, and then in one or more embodiments of the present specification, a geographical position is displayed according to the product position display form, at a geographical position on the map that matches geographical position information included in the traffic management weather risk product, according to the product position display form corresponding to the map zoom level; and, at the matched geographic location, displaying weather risk information contained in the traffic management weather risk product, which may include:

In the embodiment of the present specification, the weather risk information is displayed in a time axis manner, so that the weather risk information at different time points can be visually checked, that is, the weather risk information of live, short-term nowcasting, and short-term forecasting can be checked.
In practical application, because the number of the stake points in the map is large, if the weather risk information at all the stake points is displayed in the map, an interface may be cluttered and the reading experience of a user may be poor, in one or more embodiments of the present specification, when a weather risk information display instruction is received, a target geographic position included in the weather risk information display instruction may be displayed, and the weather risk information of each time point included in the target geographic position along with a time axis may be displayed in a form of a time axis.
The target geographic position may be a geographic position corresponding to weather risk information at a target stake point that a user desires to display, and the weather risk information display instruction may include an instruction sent by the user when the user desires to display the weather risk information corresponding to the target stake point, for example, an instruction sent by the user through operations of moving a cursor to the target stake point, or clicking the target stake point, and the like. It is to be understood that the weather risk information display instructions may include a target geographic location to facilitate displaying weather risk information at the target geographic location based on the target geographic location.
In practical applications, the time axis may contain time points, and the weather risk information corresponding to each time point is different, that is, the weather risk varies with each time point on the time axis, for example, the target geographical location is 9:30, forecast gale 5, 9:40, forecast gale 7. In practical applications, as described above, the electronic map may have functions of zooming out and zooming in, and the product position display form may be set based on a map zoom level, and considering that when the map is zoomed in to a certain level, stake points and weather risk information corresponding to the stake points may not be completely displayed in the map, in one or more embodiments of the present specification, when the zoom level of the map reaches a preset level, displaying geographic positions according to road segments at geographic positions on the map that match the geographic position information included in the traffic management weather risk product, and displaying the weather risk information included in the traffic management weather risk product at road segments may include:
when the zoom level of the map reaches a preset level, combining pile points to form a road section at a geographic position on the map, which is matched with geographic position information contained in the traffic management weather risk product, according to a weather risk category contained in the weather risk information, a risk level corresponding to the weather risk category and a geographic area to which the geographic position belongs;
and merging the weather risk information at the geographical position included in the road section formed by merging the pile points, and displaying the merged weather risk information at the road section.
Wherein, as described above, the weather risk information may include, in a time dimension, weather risk live information, weather risk short-term forecast information, and weather risk short-term forecast information. On the other hand, it is understood that weather includes a variety of weather types, such as: precipitation, snowfall, strong wind, big fog etc. then in this description embodiment, weather risk information can contain weather risk category, and weather risk category can set for according to the weather type, specifically can include: the combination of risk, precipitation, temperature, relative humidity, visibility, wind and road icing. The comprehensive risk can be obtained by calculation modes such as weighted average and the like according to the risk values of precipitation, temperature, relative humidity, visibility, wind power and road ice deposition.
In practical application, when the pile points are combined, the pile points can be divided according to different weather risk types, namely, geographical positions contained in the traffic line are divided so as to reflect different weather risks on the traffic line. In consideration of the actual situation, each pile point may correspond to multiple weather risk types, the pile points may be divided according to different weather risk types, the pile points may be divided according to the weather risk type with the highest risk level in the weather risk types at the pile point, and if the risk levels of multiple weather risk types are the same, one of the weather risk types with the same risk level may be selected as the weather risk type of the pile point when the pile point is divided.
In another embodiment, the weather risk type for dividing the stake points may also be set based on a default setting, for example, the stake points on the whole transportation line may be divided according to the weather risk type of the comprehensive risk by default, and the stake points may be divided according to the weather risk type of the default setting. In practical application, the default setting can be switched according to user requirements, for example, the default setting is set to be comprehensive risk, a user can be switched to any weather risk type such as precipitation or strong wind, and when the weather risk type is switched, pile points can be divided according to the switched weather risk type.
On the other hand, it is contemplated that different weather risk types may correspond to different risk levels, e.g., wind 5 may correspond to high risk, visibility 50 meters may correspond to higher risk, etc., and that for the same weather risk type, the risk levels for different road segments on the same transit line may be different, e.g.: on a certain transportation line, level 1 wind power of a road section 1 corresponds to no risk, level 5 wind power of a road section 2 corresponds to high risk, pile points of different risk levels under the same weather risk type are divided according to the risk level corresponding to the weather risk type after the pile points are divided according to the weather risk type.
In practical application, considering that a transportation line may span different administrative divisions, or span different provinces, cities, districts, counties and the like, in order to better distinguish the administrative divisions to which road segments belong, the geographical regions to which the geographical positions belong may be determined according to stake points displayed in a map, that is, the geographical positions of the stake points, and corresponding geographical position information, and stake points that are the same as the geographical regions to which the geographical regions belong in the same risk class under the same weather risk type are merged according to the geographical regions to which the geographical positions are determined, so that the stake points are merged to form the road segments according to the weather risk classes contained in the weather risk information, the risk classes corresponding to the weather risk classes and the geographical regions to which the geographical positions belong. The geographical area to which the geographical location belongs may be set as a province, a city, a district, a county, or the like according to a requirement, and the stake points belonging to the same geographical area may be stake points belonging to the same province, stake points belonging to the same city, or the like, which is not limited in this specification.
In practical application, the combined road section can be displayed in a map through technologies such as rendering, drawing and the like based on the longitude and latitude of the geographic position including the pile point in the road section, so that the geographic position is displayed on the map according to the road section at the geographic position matched with the geographic position information included in the traffic management weather risk product.
In practical application, after the pile points are divided, the weather risk information of the geographic position included in the road section formed by combining the pile points can be combined according to the geographic positions of the divided pile points, and the combined weather risk information is displayed, so that the geographic position can be displayed according to the road section, and the weather risk information included in the traffic management weather risk product can be displayed at the road section.
When the merged weather risk information is displayed, the weather risk information corresponding to each pile point included in the road section may be displayed, or the weather risk information corresponding to each pile point included in the road section may be calculated according to the weather risk types and by means of weighted averaging, the mean value of the weather risk information of each weather risk type is obtained respectively, and the mean value is displayed, which is not limited in the embodiments of this specification.
In practical applications, considering that a transportation line may be divided into a plurality of road segments, if weather risk information corresponding to all the road segments is displayed in a map, and an interface may be cluttered, in one or more embodiments of the present description, when a weather risk information display instruction is received, weather risk information that changes at each time point included in a target geographic position along a time axis may be displayed according to a target geographic position included in the weather risk information display instruction in a form of a time axis.
The target geographic position may be a geographic position corresponding to weather risk information at a target road segment that a user desires to display, and the weather risk information display instruction may include an instruction issued by the user when the user desires to display the weather risk information corresponding to the target road segment, for example, an instruction issued by the user by moving a cursor to the target road segment, or by clicking the target road segment.
In this embodiment of the present specification, in order to achieve a risk degree that a user intuitively feels a weather risk, different colors may be used to represent different risk levels, that is, a correspondence between a risk level of a weather risk category and a risk level color is preset, and a risk level color corresponding to a risk level of a weather risk category is displayed at a geographic location on a map that matches geographic location information included in a traffic management weather risk product according to a correspondence between a risk level of a weather risk category and a risk level color that is preset.
Wherein the risk level may include: high risk, higher risk, low risk, risky, no risk, etc., respectively corresponding risk level colors may include: red, orange, yellow, blue, gray. It can be understood that the risk level and the color of the risk level corresponding to the risk level may be set according to the requirement, and the embodiment of this specification is not limited.
