Estimating distances

Recommended Posts

Hi, all -

I'm conducting a seminar called "primitive navigation" and could use a bit of help. There are various "rules of thumb" that help estimate distance based on what you can see. Here are some of them:

50 meters Mouth and eyes of a person can clearly be distinguished

100 meters Eye appear as dots

200 meters General details of clothing can be distinguished

300 meters Faces can be seen

500 meters Colors of clothing can be distinguished

800 (0.5 miles) meters A person looks like a post

1 mile (1.6 km) Trunks of large trees can be seen

2.5 miles Chimneys and windows can be distinguished

6 miles- Large houses and towers can be recognized

9 miles A church steeple can be seen

If any of you have photos online or you could mail them to me that illustrate these, I'd appreciate it. Even if you have some off-shore photos of land from a distance that you could point me to, I could pick and choose some.

Thanks!!
