Murry, I believe all editions of Bowditch explain how to do this.It will be in the chapter dealing with projections.The older editions of Duttons may have the info also. You can always buy a pad of double sided Universal Plotting sheets.They are not very expensive.On the Nav.-l website there is a pdf file you can download for free for the plotting sheets. But if you want to learn or make your own "The American Practical Navigator" will explain how. -----Original Message----- From: Navigation Mailing List [mailto:NAVIGATION-L@LISTSERV.WEBKAHUNA.COM]On Behalf Of Murray Campbell Sent: Tuesday, January 27, 2004 17:30 To: NAVIGATION-L@LISTSERV.WEBKAHUNA.COM Subject: DIY plotting charts the books i'm trying to learn from mention that it is possible to make your own plotting charts on graph or blank paper, but they don't give any more info... it seems like i will need to create a map projection for the needed lattitude...i'm not sure how i go about scaling lattitude to longitude at different lattitudes...is there a formula that does this?? (i would rather not be dependent on buying and stowing a bunch of plotting charts) thanks, m __________________________________ Do you Yahoo!? Yahoo! SiteBuilder - Free web site building tool.
