- There are three elements to GPS:
- Ground Stations
- GPS knows your position and tracks time; as a result, it can calculate distance, speed, direction, and even elevation. You can also use the unit to navigate from one location to another.
- Geocaching is when someone hides a treasure (logbook, trinkets) and then provides the coordinates so that GPS owners can find them. Geocaching.com is a site that connects hiders with seekers (my words). Type in a zip code and get a list of all the items that are hidden within that area. You can also type in an address and get a list. Click on a result and get the latitude and longitude so that you can import them into your computer. Directions are given as to how to find the cache. Clues are provided.
- A cache can be more than just a treasure. He gave an example of a group of students who went to a nature preserve and recorded the coordinates of several different types of trees. Then others could download the coordinates of those trees and when they found them on their GPS units, would be able to identify the type of tree. Other types of caches: traditional, multi-cache, reverse cache, earthcaching.
- Several people also mentioned that one of the benefits of geocaching is that it gets you out into the area around your house. We often are oblivious to some of the details of our surroundings, but with geocaching you can discover things that you didn’t know were around you.

GPS and Geocaching
Yesterday I attended the eTech Ohio State Technology Conference. It was jam packed, the busiest I've ever seen it, and many of the sessions were standing-room only. As a result, I didn't get into a couple of sessions that I really wanted to check out. However, one session made the whole day worth it for me. I don't know much about GPS and Geocaching, but Jeff Good's presentation on the topic got me excited to learn more. Here are some of the important points from his presentation.
