I am wondering if someone can help me find...or provide basic instruction on how to make...something I've seen used recently with various maps. I'm talking about the square grids where the lines stop just shy of actually intersecting at each corner. There is a basically a small amount of space at each corner instead of the lines actually touching, if that makes sense.

You can see an example here (I just did a basic search for an example...the map is someone else's intellectual property): Map Example

I'm looking to either recreate this type of grid in Photoshop or even just find a blank image of this type of grid. I've searched a number of different ways but haven't had much luck.

This is my first question here, so thank you in advance for any assistance or direction!
