Mercator Plotting Sheets can be used by navigators to plot positions, lines of position, perform dead-reckoning, compute bearings from navaids, etc. These sheets use the mercator projection.
This work is based on the Geoff Kuenning's plotsheet.ps plotting sheet.
You can download any of these plotting sheet for the given latitude you are working on.
You can also download the plotsheet.sh ZSH script I wrote to generate the PostScript files. Feel free to modify the script or the PostScript code as you wish. If you improve it, i'd be glad to hear from you.
If you have any question, do not hesitate to e-mail me at th.lecomte _at_ gmail _dot_ com.
