Absolutely! I just did my entire playthrough creating my own map. You'll need excel and a basic understanding of trigonometry.

To plot a location you need 1) distance to LP5 2) depth 3) compass reading

But remember, the ocean is a 3D environment (X, Y, Z coords) but you're drawing a 2D map (X, Y). So you'll need to convert your position to (X, Y) by projecting your location to the ocean surface. Imagine a triangle drawn between a, b, c.

a = depth

b = distance on the ocean surface from LP5 to your location

c = distance to LP5 (hypotenuse)

You need to solve for b using pythagorean theorem

b = sqrt(c^2 - a^2)

Next we use trigonemetry to convert (b) from above into X, Y coordinates for our 2D plot.

x = b*cos(theta)

y = b*sin(theta)

theta is the angle from your compass to LP5. You have to do a little math to convert your compass reading into the correct angle.

Here's a conversion table.

The tick marks are 7.5deg. You can use this to add/subtract from your nearest direction. For example NW plus 2 ticks = 135 + 2*7.5 = 150 deg but then you need to add (or subtract) 180deg to change the angle to  match the perspective of the LP5 looking to your location.

Let me know if you have questions. Here's a blank copy of my Excel spreadsheet.
