Implementing Instant Messaging Between B/S and CAD Using WebSocket Technology
In order to solve the problem that the vector data cannot be read and edited by using Computer Aided Design(CAD)directly on the WebGIS,this paper proposes to realize the instant communication between Browser/Server(B/S)terminal and CAD by using WebSocket technology,and to quickly and visually realize the online editing of graphic data and CAD by using the open source NTS library and Well-Known Text(WKT)language.The application practice shows that the method proposed in this paper can efficiently solve the connection between WebGIS platform and CAD,so as to improve the work efficiency.
