Among the programs, implemented in the last years, I think that the one allowing an evaluation of the conditions of propagation, whose main window appears in the picture at left, is the most interesting for radio amateurs even if at present, by Internet, is possible to acquire such data, in almost real-time. Some time ago this program was put into the packet net of italian radio amateurs, so it is already in use by a number of them.

Another program, I think useful for radio amateurs (see picture at left), was implemented recently and allows to calculate the ground wave propagation in the long wave range as well as the correspondence between geographical co-ordinates and the WW Locator, showing also the distance(QRB) in respect to the local co-ordinates.
