polaris Supported User Environments
polaris can evaluate applications both over service areas (grid of static user terminals) and along trajectories. In both cases they can be defined using the GIS module.
Trajectories can be defined just by selecting waypoints. polaris will compute the shortest trajectory joining those waypoints.
Since a significant number of applications take place in urban areas, where masking angle conditions affect navigation performances, the option of simulating 3D environments (and, in particular, urban canyons) is a must. The use of 3D GIS data may not be justified, nor critical, in some cases given the average expense of such maps, such as when evaluating an application in a typical urban environment. For those situations, polaris includes a tool to create 3D environments starting from 2D GIS maps, the 3D Environments Tool Lite.
