Problems solved by technology

However, based on the existing display method, when the map is zoomed in, the display width becomes smaller, and the icon that the user needs to view may not be within the display range, which requires the user to perform repeated operations to find the icon again, resulting in cumbersome operations
In addition, as the map is enlarged, the icons of each item are dynamically loaded as the map is enlarged to be displayed in real time. However, real-time dynamic loading requires relatively high performance of the device, which may easily cause the device to freeze or even crash.

Abstract

The embodiment of the application provides an engineering map display method and device, and relates to the field of map display technology. The engineering map display method includes: obtaining a display enlargement instruction of a user for a displayed first-level engineering map; selecting to-be-displayed second-level engineering map data from at least one piece of second-level engineering mapdata according to the display enlargement instruction; and loading the to-be-displayed second-level engineering map data, and displaying a second-level engineering map. The second-level engineering map corresponding to the display enlargement instruction is accurately displayed, and cumbersome operations brought by cases where an icon needing to be displayed after enlargement is not in a displayrange are avoided; and in addition, the problem that real-time dynamic loading needs higher equipment performance is avoided through loading the second-level engineering map data at once, and equipment standstills or even crashing is prevented.

Description

technical field [0001] The present application relates to the technical field of map display, in particular to a method and device for displaying an engineering map. Background technique [0002] With the rapid development of the Internet, the traditional construction industry is now more and more closely integrated with the Internet. [0003] Currently, traditional engineering maps can be displayed on terminal devices. The engineering map is displayed on the terminal device, which can be easily viewed by engineering personnel at any time. However, on the basis of the existing display mode, when the map is enlarged, the display range becomes smaller, and the icon that the user needs to view may not be within the display range. In addition, as the map is enlarged, the icons of each item are dynamically loaded as the map is enlarged so that they can be displayed in real time. However, real-time dynamic loading requires relatively high performance of the device, which may eas...
