Just make up a value for height.

If it's really hard to do this, who's going to prove you wrong?
Will they spend the $ to redo it?
Plus, when/if they figure it out you just say that the tree grew since you measured it.
Probably best to lowball your value else the growth excuse may not work.

NEXT...

PS In case it needs to be explained, I kidding.

yep, do it all the time here the great pacific northwest doing timber cruising, works for all species of trees. If it works for the timber companies to get their inventory, must be doing something right.

First you round up a really long rope and a bowling ball bag with ball still in bag. Then you hire a helicopter for about an hour or so.

There is no correlation between having done something many times,
having done it for a long time and it being the correct
or accurate way of of doing said thing.
Ask my cousin who's on his fourth marriage.

To say you can measure the height of the tree, apparently from any angle or distance, no matter the foliage density, no matter the terrain, without positive confirmation of tree top...

Mathmatical impossibility.
Now you've entered the realm of the ludicrous.

Possible reasons:
_You still don't really understand the original post.
_You are being facetious.
_Just looking for attention. i.e. a Gadfly

Your suggestion to the poster that he simply use an inclinometer and rag tape, like the timber cruisers in the Great NorhWest is,
I think, borderline offensive to him.
To imply that he's so stupid as to not to have thought of that Beginning Surveying 1A method implies that you have some other motivation.
Especially after he CLEARLY STATED that the standard trig solution wasn't viable in is situaton.
This reinforces my conclusion that you did not, or can not, understand the original post.

A guy asks why his car won't start.
Someone asks if he put the key in the ignition.
That's not being helpful.

Timber Cruising is simply a very CRUDE form of a Topographic Survey.
Having been in Surveying for 34 years I have done many topos.
Almost all included trees. Thousands of them.
So I guess this makes me a Timber Cruiser too?

Professional Field Surveyors develop a fair level of expertise at estimating lengths and distances.
No competent professional would waste his time hand measuring each tree diameter or height
UNLESS there was a very unusual circumstance.
Then different levels of effort would be required.
Is your remarkable ability to measure any tree, anywhere maybe based on using some of these estimating techniques?
Even if you are grossly incorrect, the laws of compensating errors would kick in...thankfully.
Of course, who's going to know if you are off?

Well, we're not talking about those methods here.

For some reason, the client needs tree height or top elevation (not the same).
There are legal documents called View Easements that protect a property owner's view from obstuctions by others.
Maybe that's what's in play here. Great Northwest Timber Cruiser methods won't work.

Possible learning opportunity here for you is, like any word problem, read it through. Maybe twice.
Understand to what's being said not what you want to think it said.
This problem of listening to others and taking instuctions is a serious issue for you to work on. Will cause you much grief.
I think you were too eager to interject your vast experience as a Timber Cruiser
using gunfighter like reflexes with that trusty inclinometer on your belt.

Anyway, I've reached the end of my patience.
Spending more time would be just an exercise in futility.
Go back to your seat please.

When I started surveying, there was a party chief that would measure the height of most everything the same way.

He would pull out fishing pole with an old baitcaster reel and cast a weight over the object and measure the fishing line.

He thought the greatest thing was when the Zebco 33 came out and he didn't have to use the baitcaster reel any more.

We did that a few times to pull on-line branches out of the way.
Also used a lead weight + fishing line launched with a Whamo Slingshot.
Just "happened" to have it handy.
