Welcome to my page. The map above is a rectangular azimuthal map, output by a program of my own design. My location is the entire top edge; the vertical lines are great circles of different bearings from my location (Binghamton, NY) and the horizontal lines are circles of constant distance.
This essentially provides the same information as a conventional azimuthal map, except that it fits neatly on a small card, while remaining readable and with a high resolution of grid lines.
More stuff will appear here one day.
