Topographic Map Download

I've recently been looking around for typographic map patterns and decided (without searching around too much) to make my own pattern. It's fairly basic and super repetitive (so it's best for buttons, thumbnails, small things, etc.), so I figured that since it is so simple, maybe some of you might find use for it. Feel free to pass it on, link to it, do whatever! :-) Tag me or rebound if you make something with it! I'd love to just see it.
