Under such circumstances, there is an urgent need to develop a novel method, apparatus and medium for optimizing thermodynamic diagram coordinates in a geographical area, which reduces the amount of coordinate data to be transmitted in the thermodynamic diagram to ensure the smoothness and practical use effect of the thermodynamic diagram, while optimizing the thermodynamic diagram coordinates so as not to affect the original display effect of the thermodynamic diagram as much as possible.
The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.

In this embodiment, the dividing the thermodynamic diagram includes:

And calculating the number of coordinate points needing to be deleted in the subarea according to the set total number of the coordinate points needing to be deleted and the coordinate point density of the subarea.
In this embodiment, the total number of coordinate points to be subtracted is set according to the display effect of the geographical area thermodynamic diagram to be optimized, so as to ensure that the display effect of the optimized geographical area thermodynamic diagram is consistent with the display effect of the geographical area thermodynamic diagram to be optimized.

And deleting the coordinate points in the coordinate point sequence according to the reduced number of the coordinate points to be deleted, so as to obtain the further optimized data of the coordinate points in the subarea.
According to the geographical area thermodynamic diagram coordinate optimization method, a reliable algorithm is set, coordinate points in a sub-area are reasonably deleted according to the number of the coordinate points in the sub-area and the distance value sequence between each coordinate point and the central position, and it can be understood that the more the number of the coordinate points in the sub-area is, the more the coordinate points can be deleted; the smaller the number of coordinate points in the sub-region, the smaller the number of deletable points. By the coordinate optimization method of the embodiment of the specification, the thermodynamic diagram coordinates of the geographic area can be optimized, the occupied space for storing the coordinate data is reduced, the time for transmitting the coordinate data is shortened, the user side can display the thermodynamic diagram more smoothly and rapidly, the thermodynamic diagram can be watched more rapidly and conveniently, and the user experience is improved.
To facilitate understanding of the geographical area thermodynamic diagram coordinate optimization method illustrated in the embodiments of the present invention, the coordinate optimization method is further described below:
Because the amount of coordinate data in the thermodynamic diagram of the geographic area is large, the occupied storage space is large, and the retrieval time is long, the coordinate optimization method of the embodiment of the invention hopes to achieve the purpose of saving data transmission by reducing the amount of the coordinate data, and simultaneously ensures that the thermodynamic diagram display effect of the optimized data is similar to that of the original data.
Therefore, the coordinate optimization method of the embodiment of the invention screens the coordinate data in the thermodynamic diagram by setting a reliable algorithm so as to delete the coordinate data in the original thermodynamic diagram. The basic rule of the algorithm is that the more coordinate data need to be truncated in a region with denser coordinate points, the less coordinate data need to be truncated in a region with fewer coordinate points.
The geographical area thermodynamic diagram coordinate optimization method of the embodiment of the invention mainly comprises the following steps:
1) Dividing the thermodynamic diagram into uniform areas; 2) Counting the number of coordinate points of each sub-area; 3) Calculating the number of coordinate points to be deleted in each sub-region; 4) Calculating the central position coordinate of each sub-area; 5) Calculating the distance between each coordinate point in each sub-region and the central position of the sub-region, and sorting the coordinate points according to the distance; 6) The corresponding coordinate data is pruned according to the pruned amount.
The detailed steps are as follows:
step 1:
as shown in fig. 2, according to actual requirements, the thermodynamic diagram of the geographical Area to be optimized is divided into uniform areas, and each sub-Area is numbered and named as Area (i).
Step 2:
the number n (i) of coordinate points in each sub-Area (i) is counted as shown in the following table.
| Sub-regions | Number of coordinate points |
| Area01 | n01 |
| Area02 | n02 |
| … | … |
| Area(i) | n(i) |
| … | … |
| Area15 | n15 |
| Area16 | n16 |
Step 3:
The total number of coordinate points in the thermodynamic diagram of the geographic Area to be optimized is n (total), and according to the number of coordinate points n (i) and the total number of coordinate points n (total) in each sub-Area (i), the coordinate point density of each sub-Area (i) can be calculated, wherein the calculation formula is as follows: ρ (i) =n (i)/(n) (total).
Setting the total number of coordinate points to be pruned to n (subtraction), the number of coordinate points to be pruned in each sub-Area (i) can be calculated as shown in the following table, where the calculation formula is m (i) =n (subtraction) ×ρ (i).
It will be understood, of course, that the total number n (subtraction) of coordinate points to be subtracted is set based on the display effect of the geographical area thermodynamic diagram to be optimized, so as to ensure that the display effect of the optimized geographical area thermodynamic diagram is substantially consistent with the display effect of the geographical area thermodynamic diagram to be optimized, and no distortion condition can occur.
| Sub-regions | Number of coordinate points | Density of coordinates | Pruning number |
| Area01 | n01 | ρ01 | m01 |
| Area02 | n02 | ρ02 | m02 |
| … | … | … | … |
| Area(i) | n(i) | ρ(i) | m(i) |
| … | … | … | … |
| Area15 | n15 | ρ15 | m15 |
| Area16 | n16 | ρ16 | m16 |
Step 4:
coordinates (xi, yi) of the center position c (i) of each sub-Area (i) are calculated as shown in fig. 3.
Step 5:
distance values d (ij) between the respective coordinate points (xij, yij) in each sub-region and the center position c (i) are calculated, and the sub-region coordinate points are sorted in descending order according to the magnitudes of the distance values d (ij).
Step 6:
And (3) deleting the first m (i) coordinate data according to the deleted quantity m (i) to obtain optimized sub-region coordinate point data, so as to obtain an optimized geographic thermodynamic diagram, as shown in fig. 4.
It will be understood, of course, that after performing steps 1-6 above, the geographical area thermodynamic diagram coordinate optimization method according to this embodiment may further include the following steps:
firstly, obtaining a geographical area thermodynamic diagram to be optimized and coordinate data in the geographical area thermodynamic diagram, and displaying the geographical area thermodynamic diagram to be optimized to obtain a first display effect.
And then, displaying the optimized geographical area thermodynamic diagram to obtain a second display effect.
Comparing the first display effect with the second display effect to obtain an effect difference value, and if the difference is within a preset threshold range, considering that the optimized thermodynamic diagram display effect of the geographic area is approximately consistent with the original diagram display effect.
If the difference exceeds the preset threshold range, the processed geographical area thermodynamic diagram is considered to have the distortion condition, and the number of the deleted coordinate points is required to be correspondingly reduced so as to ensure that the display effect is approximately consistent.
