# Degrees And Minutes Need Some Help

## Recommended Posts

I am working on a multi cache where I will add or subtract numbers from coordinates to find the next set of coordinates. What is the common name for the 3 decimal places in the minutes. Fore example if I want to add 100 to those three and originally it is 50.200 and I want someone to get 50.300 how should I state this. Any ideas would be appreciated.

I think saying add x to the 'decimal portion of the minutes' should suffice for what you wish to accomplish.

There are several ways you can set this up, but I think most folks would understand if you state: Add .100 N to coordinates, or add .100 to north longitude.

There are amny ways to incorprate math into solving the final coords for a cache. Here is an example of one way: Willamette Falls Cache

UTM's are a real easy way to add or subtract numbers to get new coordinates. And I've done one with another coordinate system that works well also.

You might even want to use existing numbers from signs or monuments that will not move like # 25

Having had diffculty myself with this issue when the explanation wasn't specific enough, lead to the creation of a tool to help. If you'd have said, "add 59 to the latitude," how would that be interpreted? That's quite a jump actually. I found myself trying different options .59, .059, etc. and comparing the distances. Depending on the number, you can arrive at a number of apparently valid adjustments. So I went on to create this multi-tool that additionally does a lot more including playing these different options automatically and taking the small circle at the given latitude into consideration,

Above all, like the advice given indicated, English is a rich language, you don't HAVE to be vague, be precise.

Of course, feedback and ideas are welcome.

Here is a site that will help with some Survey Coordinate Basics.

Good Luck.
