While employed by our favorite uncle, MGRS and Depth gauge. You’re also taught lat & long and depth. You become fluent in both. Then you have the fun and enjoyment of learning knots, nautical miles, miles, kilometers. Just when that shit didn’t scramble your egg enough, you had feet and fathoms (1 fathom = 6 feet). Civilian side of the house, it’s Lat & Lon- depth is in feet. (Salvage diving) Pay attention to the legend on the map, it will tell you what system of measurement you’re using. x————-x = 1km - you’re using the metric system X—————x = 1mi - you’re using the system that puts people on the moon X—————x = 1Nm - damn Navy. There’s also toppo maps of the sea floor that are *** relatively accurate *** from hydrographic surveys. I use *** relatively accurate *** because due to tides and storms, the sea floor shifts. Using a 10 year old map, that sand bar in the middle of the channel WAS 3 feet below the surface, and 15 yards long. Today, it may be an island, or it may be gone. ______________________________________________________________________ "When its time to shoot, shoot.

When using a decimal GPS coordinate the question is how many decimal places do you use, or how accurate do you want to be? Some people go to 8 places… On the other hand there is a free and very simple app to use called “ What Three Words” that has decided the complete planet into 10’ by 10’ squares. It is very intuitive to use and can be exported to Google Maps to navigate to virtually any point on earth. The NPS is using it particularly in SAR. ------------------ Eddie Our Founding Fathers were men who understood that the right thing is not necessarily the written thing. -kkina | |||

My 5th grade teacher gave us a way to remember longitude and latitude lines. She said, “When you launch something, it goes up, so just think “launchitude.” That has always worked for me. Retired Texas Lawman | |||
