Grid method for drawing city map and application thereof

Abstract

The invention provides a grid method for drawing a city map and application of the grid method. The grid method for drawing the city map is characterized in that Yuan grids are designed through the grid technology, decimalism is determined, grid measurement units such as a grid cell, a basic unit and a subunit are created, wherein each basic unit represents the actual area of 1km*1km=1km<2>, and each basic unit is 100 times larger than a last-level basic unit; according to the technical feature of the earth meridians and parallels, the conclusion that the actual meridians and parallels of the city map are similar to grid lines of the Yuan grids is drawn according to the calculus theory, the city grid map is drawn based on the conclusion, and each information name on the map must obtain a unique regular grid code name; then auxiliary charts are developed, and therefore a larger amount of map information can be transferred to the auxiliary charts from map pictures. In this way, the contradiction between continuous increase of the information amount of a printing map and a limited area of the picture of the printing map can be solved, and due to the fact that the grid map and the digital technology are docked, it is predicted that the grid method for drawing the city map can provide support for municipal engineering, national defense and military and urban modern management.

Description

Technical field: [0001] Belongs to the subject of geography, professional map drawing. technical background: [0002] There are many types of map drawing, such as world map drawing, country map drawing, provincial map drawing, city map drawing, ---. Longitude and latitude lines are generally marked for large-scale map drawing, and most of the small-area city maps are not marked, but they all abide by the rule of going up north and down south. The area is too large, there are many streets and place names, and the bus line network is dense, so that the map is so dense that it is difficult to find out the direction of the bus route with a magnifying glass. It is also difficult to find blocks and place names, which brings inconvenience to citizens. The outsiders are even more miserable---! The above photo is still a case where a large amount of information has been deleted. There were many large companies and sub-important public facilities that should have been on the map, bu...
