CZ32870U1 - Aid for teaching how to read altimetry line and area marks in cartography - Google Patents

Description

Technical field

The technical solution relates to the production of a device intended for teaching the general ability to read the line and area means indicating altitude in 2D maps.

BACKGROUND OF THE INVENTION

When reading elevation markers in 2D maps, a large number of people experience difficulties reading bar and area markers to give the impression of 3D space. Reading altimetry in maps is imaginative and makes training difficult.

Therefore, when teaching imagination to read altitude, 3D maps made of plastic molding are used that contain physically 3D space and are suitable for beginners. With the perception of 3D space, this type of map can also be used as a touch, which makes the tool effective and highly desired. However, these maps are space-intensive for storage and handling.

Apparently 3D lenticular maps are also used to teach imagination to read altitude in maps. These aids are used to compare two cut-outs of identical space. One viewport contains the elevation tool in 2D and the other viewport contains the same elevation tool in a seemingly 3D image. Their use is very efficient and with their help students quickly achieve very good results. However, their disadvantage is the limited scope of the problem.

The essence of the technical solution

This disadvantage of the present state is partially eliminated by the didactic aid according to this technical solution, which consists in the fact that it consists of two equally large map parts, one part being a 2D map of a certain space, scale and cartographic content with an elevation expressed in area mark. the background and the second part is a seemingly 3D map with spatial effect processed by lenticular technology with the same space, the same cartographic content, but with the same scale but the elevation expressed by a bar mark placed on a 2D background, the whole seemingly 3D lenticular map is cut into a certain number puzzle pieces, but at least two pieces so that the content of one piece immediately follows the content of the next piece and the pieces, which is made up of this seemingly 3D lenticular map, are intended to be thrown in all directions and subsequent composition according to the base map

Example of technical solution implementation

The task of the aid is to teach the student to read a cut from the 2D tourist map of the Giant Mountains 1:25 000 center with a size of 21 x 21 cm, where the slope is used as a means of expressing height.

In addition to the 2D part containing the slope, a cut of the same size of 21 x 21 cm is used for teaching, where contour lines are used as line elevation marks.

- 1 GB 32870 U1

Both cut-outs contain, apart from different altimeters, identical content of the tourist map of the Giant Mountains center 1:25 000.

The cutout containing the line elevation mark is processed by lenticular technology to a seemingly 3D image with a spatial effect of 10 to 12 partial images for a lenticular film thickness of 0.35 to 0.5 mm in which the number of lenticulars per inch is between 75 and 100 and the difference in the position of the objects in the borderline images is 0.75 to 0.85 cm in the background and 0.65 to 0.75 cm in the foreground of the resulting 3D image.

This seemingly 3D image with spatial effect is cut into 16 pieces of equal size and the cut 3D map is placed on a 2D map so that it precisely overlaps it. The students will throw all 16 pieces of 3D map in all directions by leaving the existing A4 space and the whole 2D map with shaded relief will appear in the center of the student's attention.

Then the student collects individual 3D pieces containing a 3D map with relief expressed by contour lines and places them back on a 2D map where the 3D pieces with a bar mark obscure the corresponding 2D content with the area mark.

After finishing the compilation, the entire 3D map is assembled, which completely overlaps the 2D map.

The effectiveness of teaching using seemingly 3D lenticular maps is that in these seemingly 3D images, students perceive 1/3 more information (height, length, width) than 2D (length, width). This creates a qualitatively stronger commemorative footprint, which is preferred over the commemorative footprint created by 2D perception.

It can be assumed that after a period of study that is individual to each student, with the aid of this aid, he will be able to imagine the relief displayed by the contours of the contour lines and vice versa.

Industrial applicability

The technical solution can be used in the production of teaching aids for reading altitude in 2D maps.

PROTECTION REQUIREMENTS

Claims (2)

CLAIMS 1. A teaching aid for reading altitude bar and area marks, characterized in that it consists of two equally sized map parts, one part being a 2D map of a certain area, scale and cartographic content with an altitude expressed as a surface marker serving as background and the expensive part is a seemingly 3D map with a spatial effect processed by lenticular technology with the same space, the same cartographic content, with the same scale but a bar-level elevation, which is laid out on a 2D background, the entire seemingly 3D lenticular map is cut into a number of pieces however, at least two pieces so that the content of one piece immediately follows the content of the next piece and the pieces that make up this seemingly 3D lenticular map are intended to be thrown in all sides and subsequent composition according to the base map. 2. Aid for teaching reading bar and area marks in cartography according to -2E 32870 U1 of claim 1, characterized in that: The 2D map contains an elevation with a bar marker and the seemingly 3D map contains an elevation with a flat marker.
