Hi, Since someone liked my calendar tool, my latest is about global navigation; interesting and useful little toy to amuse with. I fould lists of US and World cities with their coordinates already listed; and for Brits, got all the top level post code prefixes. The tool will calculate the great circle, which is to say, the shortest possible distance, as the plane flies you might say; and the relative great circle and rhumb line courses. It gives the reciprocal too. Some one could specify more or less any two points on the globe and get meaningful results. Some are surprising, unless you're familiar with this already, then it is just proving what you suspected. It demonstrates why planes from europe to Japan go over the north pole and not east as you might think. http://randex.apearl.net/tools.php?op=longlat If I can add to it or improve it in osme some way, let me know and I'll see if I can do it. zip code would compliment the UK postcodes of course, but it would involve finding a ready made list from somewhere. I can wrap the mechanics round it if someone found such a list. Thanks, RobH. _______________________________________________ Blinux-list mailing list Blinux-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/blinux-list
