Abstract

The invention discloses a GIS application multi-screen interaction method based on a WebSocket technology. A WebSocket technology is adopted, operations of GIS applications are encoded, and multi-screen interaction between multiple devices and between two different GIS applications developed based on the same map engine is achieved through transmission of a message bus server; particularly, when the GIS application with very high hardware performance requirement of a receiving end is carried out, the control end can use the GIS application with very low hardware requirements to realize multi-screen interaction with the GIS application of the receiving end, so that the GIS application for commanding the operation of receiving end equipment such as a large screen and a high-performance PC can be controlled through mobile phones and panel light mobile equipment, and the GIS multi-screen interaction is not limited by hardware performance.

Description

technical field [0001] The invention belongs to the technical field of GIS application, and in particular relates to a multi-screen interaction method for GIS application based on WebSocket technology. Background technique [0002] GIS (Geographic Information System or Geo-Information system, geographic information system) is a specific and very important spatial information system. A technical system for collecting, storing, managing, computing, analyzing, displaying and describing geographically distributed data. [0003] Existing GIS applications, especially GIS applications in 3D scenes, have high requirements on the hardware environment and require high-performance graphics cards. However, the hardware configuration of mobile devices such as mobile phones and tablet lights is relatively low, and some applications with high hardware requirements cannot be run. For GIS applications, in some usage scenarios that require multi-screen interaction, it is impossible to realiz...
