Blank graticules

[gilgamec]

I've been surprised recently to see threads like this and this; requests for blank graticules. It hadn't occurred to me that most people on these forums who draw their maps directly in Illustrator, Photoshop, or what have you, rather than produce them procedurally like me, wouldn't be able to create them from scratch! My setup, however, makes it really easy for me to make graticules in any projection. To help out the community, I've made up a bunch of blank graticules and bundled them together as PDFs, which should be openable in most apps. Some examples:

That's graticules (with the Earth's continents drawn for reference) of the Mollweide, Winkel Tripel, Armadillo, loximuthal, Guyou, Lagrange, polar orthographic, and 180 degree sinusoidal projections. The package also includes Mercator, Miller cylindrical, equirectangular, Cassini, stereographic, Lambert azimuthal, Eckert 4 and 6, Airy, Aitoff, Peirce, and van der Grinten 1 and 3. The formulas are taken from Snyder's "An Album of Map Projections", which is available online at http://pubs.usgs.gov/pp/1453/report.pdf . Each projection has three files: one, as shown above, with the graticule and the Earth for reference; one with latitudes and meridians every 15 degrees; and one with lines every 5 degrees.

As I said, these are really easy to generate, so if I can do anything to make these more useful, let me know!
