How do you convert UTM????

[+Team Boogidy]

Okay, I'm sure that this has been covered before, but I've looked and I can't figure out how to convert UTM.

 

Please help!

 

Thanks Mama Boogidy

Goto this web page, It may be what you need.

I don't recommend the jeeep.com converter. Iv'e seen too many errors there as have others. Try this site or just use your GPS. Also, depending on what exactly you are doing, you may need to translate datums as well.

All your suggestions were very helpful, I got the info I was looking for. I'm kinda emberassed that I should have figured some of this out on my own

 

Thanks again,

Mama

Yikes! I have used this site to help me find and hide caches. Please provide an example of an incorrect conversion, or at least the threads that discuss particular errors.

 

Thanks,

I just use my GPS!

 

Just make sure you change the format and datum to the correct units, make my UTM waypoint, then change back to normal position and format, and waypoint now shows correct conversion. It worked flawlessly on this cache:

I use USGS topo maps quite a lot for all my outdoor activities including Geocaching, so I use the UTM coordinate system in the NAD27 datum. Here's an example which is the location of my house. WGS84 coord's are N38°52.38588' W076°40.03086' Converted to NAD27 UTM coord's using my gps, the site I refered to, and other software I have tested, should be easting of 355341.11 and northing of 4303804.372 Jeeep.com gives me easting of 355342 and northing of 4303793 A northing error of 11 meters. Iv'e heard of worse errors but I don't recall if it was in these forums or maybe the sci.geo.satellite-nav newsgroup. It's been quite a while since I first noticed the errors and I haven't used the site since. There are different methods for transforming datums but I prefer to use one that agrees with my gps.

I always use my GPS to convert map datum and format. When I use UTM format it is normally with NAD27 datum. I noticed they started including UTM Format for caches, but they are in WGS84 datum.

You're right; UTM in WGS84 is not very useful. Why don't they do it in NAD27? I end up converting it anyway whenever I want to use a topo map.

[+Poindexter]

If you use USAPhotoMaps or GEM these maps are in NAD83 (same as WGS84 as far as your GPS is concerned). If you use ExpertGPS then you can select which datum you want to use. Also, there are some USGS topo's that are in NAD83 and if you use programs such as Oziexplorer or Gartrip you also can select to have coordinates in NAD83.
