Background

At present, the acquisition mode of line measurement section data is basically that the line central line and the elevation point data of both sides are measured actually, and the data is displayed on a topographic map, and then the information data table of section points is formed, and the data is very single, only contains the distance and the elevation information of the section points relative to a main point, breaks away from the topographic map used for data interpretation, breaks away from the topographic features and surface feature distribution which influence interpretation, and leads to the next section data inspection work steps to be very complicated: and (3) extracting the mileage and the corresponding elevation in the information data table one by one, measuring the accurate position of the mileage on a line on a topographic map, and judging whether the selection of the elevation is reasonable or not according to the relevant topographic point data.

Detailed Description

Fig. 1 is a topographical view prior to cross-sectional marking in accordance with the present invention. FIG. 2 is a style and content diagram of a single cross-sectional point designation according to the present invention. Fig. 3 is a topographical view of ongoing cross-sectional point labeling in accordance with the present invention. Fig. 4 is a topographical view of completing the marking of all cross-sectional points in accordance with the present invention.

The method for processing the data of the line planning section comprises the following steps:

the method comprises the following steps: the planned route is marked on a topographical map marked with elevation data. Specifically, as shown in fig. 1, a broken line with a starting point a01 is a planned route, and the planned route marked on the topographic map is based on a middle line of the planned route. The area on the topographic map marked with elevation data is all the areas that may be affected by the line engineering construction.

Step two: and determining the section points to be marked on the line based on the mileage data relative to the principal point on the line. The point positions of the cross-section points are interpreted, and one cross-section point is determined on the line at regular intervals according to the total mileage of the line.

Step three: and determining the elevation data of the section points to be marked at least based on the elevation data of the topographic map around the section points to be marked. Specifically, according to the elevation data around the cross section point, a proper elevation point is selected, and the elevation data of the cross section point to be marked is obtained through calculation by an interpolation method. In addition, more accurately, in consideration of topographic and geomorphic changes and ground feature distribution, the elevation data of the section to be marked, such as the elevation of the steep bank position, is obtained by a difference method, the corresponding bank height needs to be subtracted from the elevation of the bank top position, and the corresponding water depth needs to be subtracted from the elevation of the river bank position.

The determined cross-sectional points are collated in a data sheet, such as Table 1, containing mileage and elevation data for subsequent review. More precisely, the data sheet contains mileage, elevation, terrain and landform change data, and terrain and feature distribution data.

Mileage	Elevation (L)
		0	525.87
12.437	525.18
		26.581	522.36
31.787	522.19
		41.525	521.25

		59.28	516.54
72.506	512.59
		86.432	507.43
…	…

Step four: and marking the determined elevation data of the section points to be marked at corresponding points on the line in a marking connection line mode. Specifically, as shown in fig. 2 and 3, the marked line is a short straight line, and one end of the short straight line is located at the position of the corresponding cross-sectional point of the line and vertically connected with the portion of the line where the corresponding cross-sectional point is located. The intersection point of one end of the short straight line and the line represents the point position of the section point, and the other end of the short straight line is only provided with one number to mark the elevation of the section point. The point positions of the current cross section points and the corresponding elevations are simply and visually marked on the line, so that the read cross section points and the non-read cross section points are visually distinguished. The length of the short straight line may be appropriately determined depending on the beauty and clarity and the size of the blank area on the topographic map. The short straight lines are arranged in a vertical mode, so that the short straight lines are very clear and attractive after all the section points are marked on the line.

In one embodiment, the labeled elevation data is a different color than the elevation data itself labeled on the topographical map. The color of the reticle may be the same as or different from the color of the elevation data being marked. In an alternative embodiment, as shown in FIGS. 2 and 3, the elevation data is labeled at a different elevation than the elevation data that is labeled on the topographical map itself. The font of the elevation data is marked differently than the font of the elevation data marked on the topographical map itself. In yet another embodiment, as shown in FIGS. 2 and 3, the font orientation of the labeled elevation data may be different from the font orientation of the elevation data itself labeled on the topographical map.

The marking process of the point position and elevation data of the section points can be completed in AutoCAD by adopting Visual Lisp program language. Of course, any other suitable image, data processing software may be employed for execution.

Step five: and repeating the second step to the fourth step to finish the marking of all the section points to be marked of the whole line. Specifically, as shown in fig. 4, a topographic map marked with a marking line and marked with point locations of cross-sections and elevation data on the marking line is obtained.

After marking of all the section point data is completed, checking point position and elevation data of the marked section points, wherein the checking step comprises the following steps: firstly, whether point positions and elevation data marked by the sectional points are matched with a topographic map or not is checked, and then whether the elevation data marked by the sectional points are consistent with the elevation data in the data table or not is checked. The complicated working step of section data inspection becomes concise and intuitive by marking section points.
