triangulation on a topo map |
Clearly bamboozled by the notion that anyone would want to "triangulate" something, Ivanov just Googled the phrase, and the very first result was some blog called "CompassDude" explaining how to find your location when you're out hiking. So, that's what Tatyana ran with:
"Imagine that you're lost in the woods with your compass and topographical map. To find your way back to a trail and safety, you must triangulate your position."According to our map lady, from that point forward Tatyana did a semi-good copy-reword-paste job on CompassDude's instructions... until she didn't That's why someone flagged this post for nomination. The reasons for the DotD are multiple, including:
- Tatyana said you're "lost in the woods": unless the trees are pretty short, you can't see any landmarks for orienting yourself.
- She decided you need a protractor. That's not true if you have an orienteering compass. If you don't have an orienteering compass, Tatyana's instructions are of no use.
- Who carries a protractor on a hike, anyway?
- Ivanov says that the bearings to two landmarks are "translated onto your map to determine your location." No, they're plotted on the map. We have no idea where that "translated" comes from.
- Tatyana says to, "Draw a straight line with a pencil and protractor from the landmark on the map using the bearing indicated by your compass..." except that it's easier to just use the base of the compass... if you did it right.
Oh, and for what it's worth? nobody said anything about getting lost in the woods: people use triangulation all the time – and so do cell towers!
