In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
In this embodiment, a method for drawing a distribution diagram is provided, which can be used in environmental, meteorological and geographic monitoring systems, such as air detection systems, temperature detection systems, river monitoring systems, etc., fig. 1 is a flowchart of a method for drawing a distribution diagram according to an embodiment of the present invention, as shown in fig. 1, the flowchart includes the following steps:
and step S101, generating GIS data as a distribution map base map through GIS data processing software. Specifically, GIS data can be generated rapidly and conveniently through GIS data processing software, so that a distribution map base map can be generated rapidly, and the timeliness of the data is ensured.
And step S102, loading the administrative division data for the distribution diagram base by calling a matplotlib drawing library and a cartopy package of python to obtain the administrative division base. In particular, Python has advantages in processing data, such as fast development speed, small code amount, and rich data processing packets. The matplotlib drawing library and the cart package called by the embodiment of the invention are data processing packages possessed by Python, and terrain elements are superposed on the distribution map base map by calling open-source cart terrain data.
Step S103, acquiring environmental elements and/or meteorological elements of each site.
And step S104, drawing a first spatial interpolation distribution map according to the administrative region base map and the environmental elements and/or meteorological elements of each station. Specifically, in the embodiment of the present invention, when the interpolation distribution map is drawn, geographic elements, environmental elements, and/or meteorological elements may be displayed in the map, so that any superposition of the interpolation distribution map display elements is realized.
And step S105, performing level rendering on the first spatial interpolation distribution map according to the environment elements and/or the meteorological elements, and drawing a first region rendering map. Specifically, the embodiment of the invention performs level rendering on the environmental elements and/or meteorological elements in the process of drawing the interpolation distribution diagram, realizes the random superposition of the elements in the region rendering diagram, and is convenient for users to observe.
The spatial distribution map in the traditional technology can be realized in different modes, but the environment element and the meteorological element can not be arbitrarily superposed on the geographic element, and the drawing is only carried out through an inherent template, so that the method is only suitable for the drawing requirement of the current scene and can not be universal. Through the steps, the embodiment of the invention combines the geographic elements (geographic administrative division data) and the environmental elements (AQI and PM)2.5、PM10、SO2、CO、NO2、O3) The spatial interpolation distribution diagram, the region rendering diagram and the city and site dot diagram are drawn by randomly superposing meteorological elements (wind, temperature, humidity, air pressure and precipitation), so that fusion of multiple sources and multiple elements and automatic drawing of the spatial distribution diagram of any region are realized, and the problems that a specific spatial distribution diagram can only be drawn through an inherent template singly and multiple types of spatial distribution diagrams cannot be drawn synchronously in the prior art are solved. The embodiment of the invention realizes the free combination of the geographic elements, the environmental elements and the meteorological elements, performs free combination drawing on the webpage under the condition of selecting the conditions according to the specific requirements of the user, realizes the drawing configured according to any area, and has convenient operation.
Step S104 involves drawing a first spatial interpolation distribution map according to the administrative region base map in combination with the environmental elements and/or meteorological elements of each site, and in an alternative embodiment, performing spatial interpolation by IDW according to the environmental elements and/or meteorological elements to form interpolated data of each grid point, where each grid point may be obtained by dividing the region to be monitored according to longitude and latitude, clipping through a geographic boundary, and drawing the first spatial interpolation distribution map according to the interpolated data. Specifically, the interpolation data can be obtained simply and efficiently by an IDW (inverse distance weighted interpolation) method, and the interpolation data obtained by this method has accuracy.
In an alternative embodiment, the first spatial interpolation profile shows the meteorological element by contour lines while simultaneously showing the environmental element and the meteorological element. Specifically, when the environmental elements and meteorological elements are displayed simultaneously in the same distribution diagram, the distribution diagram is displayed more intuitively and conveniently by displaying the meteorological elements through the contour lines.
Step S105 involves performing a level rendering on the first spatial interpolation distribution map according to the environmental elements and/or the meteorological elements, drawing a first region rendering map, in an alternative embodiment, determining a pollution level of each administrative area according to the environmental elements and/or the meteorological elements and the geo-partition codes, and performing a pollution level rendering on each administrative area according to a color corresponding to each pollution level. Specifically, each city has at least one site, and the pollution level of each administrative area is determined by the data of the sites. The region rendering map can intuitively show the pollution degree of each region through different levels of colors.
In order to further improve the diversity and visibility effect of the spatial distribution map, in a specific embodiment, a dot diagram may be further drawn, and the pollution or weather condition of each region is visually shown through the density or color of dots in the dot diagram, for example, the pollution degree of each part in a certain river is described through the density of dots. The degree of pollution of a river can be generally expressed by densely packing dots or by coloring the dots with a corresponding level of color. The spatial distribution map supports simultaneous contrast maps showing up to 4 years, in addition to different types (interpolation maps, rendering maps by regions, dot maps) and different time scales (hours, day-average, year-average, time interval).
In any of the above embodiments, the environmental elements include at least: PM (particulate matter)2.5、PM10、NO2、SO2When the concentration value of CO is determined, PM is calculated2.5/PM10、NO2/SO2、SO2/CO、NO2Ratio of/CO, PM of each site is combined according to administrative division base map2.5/PM10、NO2/SO2、SO2/CO、NO2Ratio of/CO, second spatial interpolation profile, according to PM2.5/PM10、NO2/SO2、SO2/CO、NO2And performing level rendering on the second spatial interpolation distribution map by the ratio of/CO, and drawing a second zone rendering map. Utensil for cleaning buttockBody by calculating PM2.5/PM10、NO2/SO2、SO2/CO、NO2The ratio of/CO can further evaluate the condition of the environment, so that the monitoring result is more scientific and provides guidance for subsequent judgment.
Specifically, by PM2.5、PM10、NO2、SO2Concentration value of CO and PM2.5/PM10、NO2/SO2、SO2/CO、NO2The ratio/CO can be judged as follows: when PM2.5/PM10Is less than 0.4 and PM10When the concentration of the dust is higher, the influence of the dust on the current environment can be judged; when NO is present2/SO2And NO2When the numerical values of the mobile resources are greatly changed, the situation that the mobile resources are obviously increased in the current time period can be judged; since CO is a relatively stable gas, SO2the/CO can objectively evaluate the SO2The change trend of (2) can judge the condition of industry/fire coal in the current time period; for the same reason NO2the/CO can also be used for more objectively evaluating NO2The condition of diesel consumption and emission in the current period can be judged.
