Grids in GIMP

[Jacktannery]

Don't worry I had no idea idea when I started using GIMP. I used to draw a grid in crazy ways until I found the function under Pattern.

Here's a video I made on the basics of grids using GIMP. This video also shows you how to make the little "cross" markers so popular in outdoor 4e battlemaps

IIRC, there is a Filter-render-patern-Grid

Very helpful.

Thanks, I was also curious how to do this.

Thanks for the information, I was wondering how to set up a grid so I could map the equator and tropics bands.

[johnvanvliet]

for equator and tropics bands i would use MMPS or Qgis
the equatorial is easy

the two " tropics " are based on the planetary tilt

so depending on your map projection this would be very easy or a bit complex
