Embodiment Construction

[0009] The present invention regards the geographical realities and geographical elements of multiple specific historical periods in the same area as different levels on the time axis, so that the plane geographical realities and geographical elements between layers can be seen through the vertical time axis. History and magnitude of change. The method is: with the same scale and legend, complete maps of the same area and different historical periods are drawn on thin transparent flat materials in the form of one page per historical period.

[0010] The map produced by this method includes several pages, and the material of each map page is a thin transparent plane material, and the scales and legends of each page map belonging to the same region and different historical periods are the same. The thin transparent plane material can be made of transparent plastic. For the convenience of preservation, each map page can be in loose-leaf form, and a loose-leaf hole is formed on t...

Abstract

An overlapped historical map features that the maps of same geographic region at different historical periods are drawn on different transparent pages by same proportion rule, and the different maps on different transparent pages are overlapped to directly understand the variation of said geographic region with different historical periods.

Description

technical field [0001] The invention relates to a superimposed historical map and a production method thereof. Background technique [0002] The current historical maps, whether they are full maps or sub-maps, are drawn on ordinary paper according to each historical period, and then bound into volumes. In order to understand the changes and evolution of geography, territory, administrative districts, place names, etc. in a certain historical stage of the same region, as well as the change process and range of geographical elements in the same region, it is necessary to compare and review multiple historical maps, which is very inconvenient to compare. The magnitude of the change is not easy to see intuitively. Contents of the invention [0003] In view of the above, the task of the present invention is to propose a superimposed historical map and its production method, from which the geographical reality of a certain historical stage, the evolution process and the range o...
