Problems solved by technology

[0002] In the known technology, on various maps including traffic maps, it is often necessary to mark road marks, but for the representation of road distance and distance, it is basically by using a scale or directly marking the actual mileage on a specific road section. The former uses It is necessary to measure and estimate the distance of the line segment with a straightedge first, and then convert it into a rough mileage; the latter can only estimate roughly; in short, because the actual road markings on the map are mostly curved, the above method can only estimate the mileage, and the actual error is relatively large

Embodiment 1

[0008] Embodiment 1: road mark 2 is marked on the drawing surface 1, and the mileage mark 3 is marked equidistantly on the road marking 2, and the legend 5 is also marked on the drawing surface 1, and the n power pair of 10 of the legend 5 adopts the mileage unit Mileage marks 3 units for illustration.

[0009] Auxiliary markers 4 are equidistantly marked on single mileage markers 3 . Auxiliary mark 4 can be finely marked.

[0010] Road mark 2 is marked with a strip curve, mileage mark 3 is marked with equal-length color blocks, and legend 5 marks the mileage represented by the length of the color block. At this time, the auxiliary marks 4 are equidistant color bars thinner than the mileage marks 3, and these color bars may be of the same color or of different colors.

[0011] Road marking 2 is marked with a single curve, and mileage marking 3 is an equidistant line segment perpendicular to the curve of road marking 2. Figure 5 shows the corresponding actual mileage between ...

Abstract

The invention relates to a visual marking method for a distance in a map, which comprises the following steps of: marking a road mark (2) on a map (1); marking a mileage mark (3) at equal distance on the road mark (2); also marking a legend (5) on the map (1), wherein the legend (5) illustrates the unit of the mileage mark (3) by adopting 10<n> of the mileage unit; and directly marking the mileage mark (3) on the road mark (2) on the map (1) by 10<n> unit. The invention has the advantages of convenient and clear marking and rapid and accurate reading and conversion and is suitable for various road marks (2), such as straight lines, curves, and the like.

Description

technical field [0001] The invention relates to the technical field of traffic map road markings, in particular to a method for visually marking distances in maps. Background technique [0002] In the known technology, on various maps including traffic maps, it is often necessary to mark road marks, but for the representation of road distance and distance, basically all are by using a scale or directly marking the actual mileage on a specific road section. The former uses It is necessary to measure and estimate the distance of the line segment with a straightedge first, and then convert it into an approximate mileage; the latter can only estimate roughly; in short, because the actual road markings on the map are mostly curved, the above method can only estimate the mileage, and the actual error is relatively large. Contents of the invention [0003] The object of the present invention is to provide a mileage marking method that can effectively improve the accuracy of milea...
