Graphics are the main means used to quickly disseminate information to a wide range of users. Due to its importance, Web applications also have to consider graphics as a major issue to embed them. However, for Web applications, issues such as interoperability pop up. Therefore, the idea of this paper is to exploit existing web standards (XML, SVG, etc.) for use in visualizing a Rocket Trajectory path in a cartographic map projection. This application software deals with data obtained from a database so some animation procedures can be deployed. Zooming facilities are also enabled to verify, for example, launch pad region. A detailed trajectory analysis can be conducted by visualizing the projection of the vehicle's position in a map. Moreover, for each of the vehicle's position, other parameters such as velocity, acceleration, mass, etc. can also be seen according to the specified position. There are several ways to perform the analysis. One way is to simulate the flight evolution in a real time scale. Another alternative is to simulate the flight on a step by step basis or even based on events that will affect the trajectory. There is one more option that is to obtain the data associated to the vehicle's position by clicking a position on the map. Examples of use of this application will be presented.
