SignalGen - SignalGen is a free (GPL) Linux (Xwindows GUI-based) utility that generates relatively low frequency signals with the use of a PC sound card. It is an entirely suitable replacement for a hardware signal generator if one doesn't require signals of a frequency higher than about 50 KHz. SignalGen creates any frequency between a fraction of one Hertz and an upper limit determined by your sound card's capabilities.

AZMap - Azimuthal maps generator - AZMap is a freeware Windows program for the Windows PC which will generate, display, and print an Azimuthal-Equidistance (A-E) map of the world, centered at any point on the surface of the earth (except very near the poles). The A-E map is also known as a Great Circle map since straight lines from the center point to any other point always fall along a great circle path and represent the shortest distance between the center and that point
