Geocaching Coordinate Distance Calculator

So I’ve come across more than one puzzle cache that goes something like this: you are given a coordinate. The description then tells you to go X feet from the coordinate heading y degrees. How do you calculate the new coordinates?

No Latitude

Well, you perform some trigonometry to identify the longitudinal and latitudinal distances then perform some algebra to convert those distances into coordinates. Something new that I learned is that the distance between each longitudinal degree is different than the distance between each latitudinal degree. Hence you have to use different divisors for each to determine the coordinates.

The calculator still needs to handle situations where the distance hops over a longitudinal or latitudinal degree, but for most puzzles of this type the calculator will work fine. The calculator even handles jumps over degrees, so adding thousands of feet shouldn’t trip it from providing the correct coordinates.

Here’s what to enter:

  • Distance (Feet) = the distance from the center point in feet. If you’re interested in metric entry and results, post a comment.
  • Heading (Compass Degrees) = the heading in compass degrees. 0 degrees is due North, 90 degrees is due East, 180 degrees is due South, and 270 degrees is due West.
  • Latitude of Origin “N” = coordinates in the format “N XX° YYY.ZZZZ'” where XX is the degrees and YYY.ZZZZ is the decimal minutes. This is the common form that provides for coordinates.
  • Longitude of Origin “W” = the same as the Latitude, only for Longitude. Because it’s frozen as “W”, this calculator will only work for the western hemisphere. Let me know if you’re in the Eastern (or Southern) hemisphere and would like me to update the calculator to accommodate you.

The Calculations are for nerds. The Results are for you. The coordinate results should display a link to Google maps when you’ve entered in all the criteria.

Update: 2017-06-15, I corrected the algorithm. Instead of using the angular distance, it uses a formula based on Haversine distance equation.

Have fun and post a comment to let me know if it’s useful.

New Textures – Two Introductory Sets

When I was young I just wanted to make stuff for the pleasure of it. When I got older I was told that wasn’t a way to make a living.

I disagree. God made things for a living so I guess those people’s attempts to civilize me into a common worker bee never quite stuck because of my higher childlike “ideals”.

My parents were pretty good with supporting me through it. Mom is an excellent painter and Dad is a great musician. They weren’t like the other grown ups who usually attended school board council meetings. That is, they weren’t looking for a way to build a society – just looking for a way to raise great kids.

If more people took up their personal responsibility to raise their kids instead of handing their kids off to the village (idiots) to raise them, I think they would discover that children are important… they’re a joy… they bring back those squishy playdough, colored in fingerpaint, bruised knees from playing in the rocks moments. That imagination is never really lost – not completely, anyway – it’s just suppressed. And like a good expectorant, when you have kids that creativity just spits right back up!

The iPhone Crowd

For the technophiles who understand the grunting undertones of the UK’s hit television series “The IT Crowd” and who also happen to understand the grunting undertones of the Tim Allenisms when it comes to modern technology (and who happen to be fortunate enough to own an iPhone) we have a special treat for you today!

The IT Crowd Ringtone.
It’s the free remix track offered by Painting By Numbers trimmed down to fit and converted to be read as an iPhone ringtone. Certainly it would have been nice to keep the full 47 second hum-dinger, but Apple forces some limits on this no matter what the file size.

Originally, I wanted to make a ringtone that would loop nicely – and did, but it didn’t start off where I wanted it to. Besides, who lets their phone ring for more than 30 seconds?

So I opted to just trim out the middle – you get the start and the finish. It’s like a bologna sandwich without the bologna!
