[Space] Planetary maps
G'day
Does anyone have any tips for producing planetary maps in the format suggested for GURPS Space (i.e. icosahedral projections tessellated into hexes). I'm no great draughtsman, so a technique for automatically generating maps that conform with a planet's hydrographic percentage would be very handy. Failing that, what good ways are there for simply getting the spread-out-icosahedron of hexes superimposed on a graphic so that it can be included into a document and print out nicely> - Brett

EDIT: as that link doesn't seem to work anymore (at least, it wasn't on 30 May 2017), to make a hex map with a spreadsheet, make the dimensions of each "square" 1 unit tall x 1.1547* units wide. A "square" will likely be made up of two rows, so that the "squares" of a column are offset vertically by half a "square" from adjacent columns. * The exact value is 2/SQRT(3) units.

Re: [Space] Planetary maps
Very timely that nearly a decade later you updated your post! I was just looking for advice about this.
Can you elaborate a little more on how to do it? I'm aiming to merge Traveller style standard 1000km world hexes with a GURPS style isocahedral plus polar map formatting. Potentially with latitude and longitude lines. My graphic design skills are weak... |

Here is an example where I'm using a spreadsheet to illustrate my defense options. In this case, each "hex" is 6x6 cells.

Re: [Space] Planetary maps
A thing I did once while programming a game, and can't think of a better place to put it, was numbering columns sequentially, and rows alternatively odd and even.
So column 2 would have its hexes labeled 22, 24, 26, 28, etc., column 3 would have 31, 33, 35, 37, etc., and hex 33 would be surrounded by (clockwise from the "north") 31, 42, 44, 35, 24, and 22. This makes it easy to calculate the screen position a token needs to be drawn at, and distance between two hexes is easy to calculate in a program, as (ABS(X1-X2)+ABS(Y1-Y2))/2.

Re: [Space] Planetary maps
Couldn't you format some of the table-cell "hexes" to have an internal diagonal line, then set others to have the appropriate top or bottom borders, and thus through really nitpicky formatting get the appearance of hexes rather than of staggered squares?
(Of course, at that point, you might as well throw up your hands and learn Inkscape or Illustrator.)

Re: [Space] Planetary maps
This might be totally irrelevant but figured I'd mention it: http://inkwellideas.com/2011/09/isoc...map-generator/
It's basically a generator for maps in the GURPSy style, though not specifically for GURPS. |
