A method and system for realizing industrial dynamic layer adaptive overlay slice map

Abstract

The invention discloses a method and system for realizing self-adaptive stacking and sliced ​​maps of industrial dynamic layers, obtaining the dpi of equipment running in the system as an algorithm parameter; obtaining the coordinate system of the map; obtaining the basic unit of the map according to the coordinate system of the map, if If it is a projected coordinate system, the unit is meter; if it is a geographic coordinate system, the unit is degree; select the corresponding scale and resolution conversion formula according to the basic unit of the map, and calculate the resolution of the corresponding scale; calculate the resolution of each scale After coming out, reconfigure the scale structure of the map, and then load the overlay map. The present invention can be applied to all geographic information systems, avoiding the problem of map layer data not being displayed, reducing the rework rate, thereby improving development efficiency, improving system reliability, and avoiding some problems caused by incomplete display of map data. Serious bugs in some functional modules.

Description

technical field [0001] The invention relates to the field of map overlay technology, in particular to a method and system for realizing adaptive overlay of sliced ​​maps of industrial dynamic layers. Background technique [0002] A map is a graphic that expresses the spatial distribution, connection, and development and change status of various things on the earth by using cartographic language and integrated on a certain carrier according to certain mathematical rules. With the advancement of science and technology, the concept of maps is constantly evolving. For example, maps are regarded as "images and symbolic models reflecting natural and social phenomena", and maps are "carriers of spatial information" and "transmission channels of spatial information". Wait. [0003] The carrier of traditional maps is mostly paper. With the development of science and technology, various carriers such as electronic maps have appeared. The geographic information system is to store geo...

AI Technical Summary

Problems solved by technology

[0009] 1. The dynamic layer is superimposed with the tiled map service. The scale of the dynamic layer will be limited by the scale of the tiled map, so it is easy to lose the scale level, resulting in incomplete display of layer data

[0010] 2. Under screens with different resolutions, such as computers, tablets and mobile phones, the DPI is different, which will cause scale display errors, resulting in incomplete display of layer data
