How does N20 (degrees) 52'38" W translate?

A friend gave me a survey land. In the upper left corner of the property, its says:
R=624.92
L=17.65'

What is R?

The distances are easy to discern but under each distance measurement, there is a coordinate with degrees and feet and inches with two directions.

Wow, I haven't read an explanation or tried to explain this in a while, but I'll have a go.

The N20(deg)52'38"W is an angle - it is actually an angle west of north by 20 degrees 52 minutes and 28 seconds. Believe it or not, I remember this bit from my Voyage of the Mimi lessons in 6th grade - related to steering a boat. I see you understand the distance that goes with this. So, when you are drawing this in AutoCAD, you would begin the line, then type "@87.04'&lt;N20d52'38"W". This works even if you're in decimal degrees.

The 'R' is for Radius - so that would be an arc'd line. I've usually seen this with an angle property so you can input the radius, length (L), and angle of chord connecting the ends, but I think you can still draw it with the information you have.

Slhill,
So let's take the line on the left that says 87.04 with N20degrees52'38"W

That translated to point that is 87.04 feet away at a angle that is definite by N20blahblah OR -70degrees on a x-y grid, yes?

I'm still not sure where the R, radius has to do with what point or line exactly.

I really appreciate your help! I guess I should read the Voyage of the Mimi at some point in my life!!

It's more like about +160 on the x-y grid because it is directional from the starting point, but if your at the end, it would look like -70ish.

In this case, I think the radius is so large as to make the line look straight, but I agree - that particular bit of information is lacking clarity.

The Voyage of the Mimi I remember was actually a PBS TV series, but we used it as part of a classroom social studies unit complete with ocean maps and following the boat as they tracked humpback whales.

Are you trying to enter these coordinates into say, Autocad? There's a certain (and very accurate) way to enter coordinates into autocad. I do it often when I draw plats(I label them project information site plans) as part of my residential sets. Just wondering.
