The UTM Grid 

Thank you.

I'm so pleased you like it. All the best.

Thank you for your interest. All the best.

r g You're most welcome. Glad you find it helpful.

Great. Thanks for your comment.

Go download my free ebook, "Land Navigation." www.land-navigation.com/free-ebook.html In it, you will find, among other things, a written explanation of UTM. Also, I have a four-hour video-based course entitled "Land Navigation--How to Find Your Way and Not Get Lost." www.land-navigation.com/land-navigation-course.html It costs a few bucks, so that's up to you. What it does do is take the book, and "bring it to life" you might say, via video. In any case, thank you for your kind words. Cheers.

+Jeffrey Osgood Thank you, Jeffrey. I'm pleased you found it helpful.

Thank you sir.

Thanks. I'm glad you find it useful.

+Vijay SP Glad you found it helpful. Best wishes.

I'm pleased it was helpful. I have a free downloadable ebook on my Land Nav website, which explains all the grids--lat/lon, UTM, and MGRS. I think you'll like having it. It's free. No strings. Cheers. www.land-navigation.com/free-ebook.html

Thanks for that compliment. That was the kind of video I was trying to make.

+2LearnMore I'm glad it helped. Best regards.

You'll love UTM for land nav, once you get used to it. So much easier to use over land.

I'm pleased you found it helpful.

Koseiku Hope it helps.

You bet. All the best.

Daniel Mokhtar Sure thing. Cheers.

You bet. Cheers.

Northings increase as you go north. In the southern hemisphere, northings get larger as you approach the equator. Once you pass the equator, the measurements "reset" to zero, and northings continue to increase as you go north. Northings always increase as you go north, no matter which hemisphere you're in. That's the way the system was set up.

The purpose of UTM's quadrants (those 6 degree by 8 degree rectangles dividing each zone) is to indicate north/south position on the globe. Starting from 80 degrees south latitude, they start with the letter C, and come north to 84 degrees north latitude, ending with the letter X (X quadrant is 12 degrees high), omitting I and O because the are too close to 1 and 0. N is the first quadrant north of the equator. Naturally then, N and any quadrant subsequent to it is in the northern hemisphere. Any quadrant preceding N is in the southern hemisphere. So, look to the quadrant designation to tip you off as to hemisphere. That said, some versions of UTM don't use quadrants, but instead use the letter N to refer to the northern hemisphere, and the letter S to refer to the southern hemisphere. This is confusing because when you see a full coordinate with an N or S, you don't know whether either letter refers to the hemisphere or to a quadrant. I think the N/S way of stating coordinates is going out of style in favor of using quadrant designations. Hope this helps.

Thank you, man.

+John Stanton You bet. Glad I could help.

+hemanth aradhyula I'm pleased you found it helpful.

haha so good i watched it twice

+Justito Tanedo You're welcome.

Luis Sibira You're welcome.

Thanks.

Thanks for pointing that out. Drives me nuts when people leave such to things unexplained

***** You bet.

+Wanjiku Wanjiru Glad it helped.

Not sure if you've already downloaded the video but you can use a program called RU-vid Downloader to download videos from RU-vid. It works great.

Brett Sutherland You bet. Glad you liked it.

Cheers.

You bet.

Ahmad Bawab No. These are definitely latitude lines. Latitude lines run east and west around the globe, and are parallel to one another. Longitude lines run north and south, and converge at the poles. I hope this helps.

Dennis Rogles Good question. Let's look at the northern hemisphere, for example. There are 10 quadrants from the equator to the 84-degree latitude line. The northing at the equator is 0 meters north. The largest valid northing in the northern hemisphere is 9,334,080 meters north. Now, here's where the whole thing gets tricky, to me at least. Each of those zones is not really a rectangle, but is bordered by longitude lines. In fact, each zone is 6 degrees of longitude wide. This means the zones get smaller as you go toward each pole. So, my representation of them being 6 equal squares wide from top to bottom is not exactly accurate, and neither was my understanding of zones at the time, which I thought were rectangular. Live and learn. Neither is my representation of them being exactly 10 squares tall. This is an approximation. Now, the big picture -- Each quadrangle (except X, which is taller) is roughly 1,000,000 meters tall, "roughly" being the key word. So 1,000,000 meters x 10 quadrangles = roughly 10,000,000 meters, which is of course very close to 9,334,080 meters. I hope this helps. This to me is the trickiest part of the whole UTM grid system. But good news for most land navigators is we normally concern ourselves with such a small area of operations, that we don't even have to understand the UTM design at this level. Still, it's good to know. Thanks for your interest. I hope my video has been of some help to you. Cheers.
