A process of providing an aviation navigation chart over a computer network includes receiving a request by a server computer from a client computer. The client computer is in communication with the server computer via the computer network. The request is received over the computer network. The request includes an indication of a departure point and a destination point selected by a user of the client computer. The process also includes generating, at the server computer, a composite travel navigation chart in response to the request. The composite travel navigation chart includes a travel chart image with the departure point and the destination point and a route line extending between the departure point and the destination point. Furthermore, the process includes delivering the composite travel navigation chart from the server computer to the client computer for display by the client computer.
