Great Circle Map Generator

A recent 'year end review' posting in the Amateur Radio Weekly blog, reminded me of great little piece of online software that might interest a lot of hams. It is a very nice Great Circle Map Generator, centered on your specific location.

The map generator is the brainchild of Tom, NS6T, and can be found on his 'HAM STUFF' website along with some other interesting bits. The actual map generator can be found here.The user interface is simple and map generation times are fast. Anyone with a beam will likely be interested in this, should they not already have a great circle map for their present QTH.

I used my six-letter grid square identifier for centering the map. Depending on the 'distance' value used, one can tailor the map for local / regional work or for a worldwide setting.

This is the map generated for a distance unit of 500km and would be helpful for local VHF'ing:


This map was produced when a distance unit of 4500km was used ... nice for the 6m grid square hunter:



This worldwide map was produced with an input of 18000km:


Hopefully you might find the map generator of some value in your own shack.
