Abstract

The invention relates to a method and system for displaying icon data of multiple GIS display terminals. The method for displaying icon data of multiple GIS display terminals includes: selecting a reference terminal among multiple GIS display terminals, and obtaining characteristic data of the reference terminal; sending the characteristic data to other GIS display terminals except the reference terminal terminal; obtaining icon data to be displayed at the other terminal according to the map display range of the reference terminal, and aggregating the icon data according to the aggregation range factor and map display resolution of the reference terminal to obtain the other A plurality of aggregation containers of the terminal; wherein, the icon data uses latitude and longitude to describe its coordinate position; on the screen of each GIS display terminal, the corresponding icon quantity is displayed according to its resolution and the division result of the aggregation container; it can improve the number of different GIS display terminals The efficiency of displaying a large amount of identical icon data can also improve the display effect of the above icon data on each GIS display terminal.

Description

technical field

[0001] The invention relates to the technical field of GIS display, in particular to a method and system for displaying icon data of multiple GIS display terminals. Background technique

[0002] In the field of computer display technology, it is often necessary to visually display a large amount of point data on multiple GIS display terminals at the same time. The existing technology usually draws the large data volume points in the record point data file or database one by one on different GIS display terminals, and uses an icon to represent a point on the display terminal, for example, there is a city video point map with a data volume of 1 million Layer, in order to see this video point layer data on different screens at the same time, technicians usually draw these 1 million icons on the screens with different resolutions of GIS display terminals to represent the 1 million video points.

[0003] According to the above method to draw icon points with a la...
