I need an OFFLINE Mapping Tool, meaning WITH NO INTERNET CONNECTION for me to draw a line in order to calculate distance, true heading and magnetic headings and thats it. So for example, I would pick a location in that tool and finding out the coordinates pin mark that anywhere on the globe and then draw a line and find out the heading to any point from that point.

Currently I use Google Earth for this using the RULER feature and then that would draw a line from any point on the globe and that would tell me the distance and the headings.

But I need a tool or a program were I can do the same except WITHOUT internet connection.

There is a way to use Google Earth offline, but its not promising. I read the guide for it too.

Please help. Thx.

What accuracy do you need? If plus or minus 0.5% is good enough you can assume the earth is a sphere and the formulas are fairly simple. If plus/minus 20-30 meters is good enough for distance then Lambert's formula isn't too complicated. And you can probably use the formula for normal-section azimuth-- probably won't differ from geodetic azimuth by more than 0.01 degree, unless your routes are getting close to 20000 km long.

Try using a chart and a plotter. Works every time, even offline. The only caution is to not leave the plotter on top of the instrument panel on a sunny day.

And a pencil, very important for drawing that line from A to B.

And if you are in a pinch, need to draw a line on the map and have no pen etc, take point A in your mouth, point B in a hand, then use your free hand to fold the map over .

Not the neatest way, but if it's all you have, you do it.

I have a question about something that people get confused about in the maritime world.
They use the word heading when they should be using course. Heading is the way a ship is pointing. Course is the way it's going. Is it the same in the flight universe?

Heading is where the compass is pointing, Track is the line on the ground made good.
Drift is the difference between heading and track.
