Tree measurement

[Timberframed]

This may not be interesting to most but sittin' here with a cold one thought I would post anyway. Some of the big grand trees that live near were I do could be subject to a title of champion either by region, state, county, ect. according to the North American Tree Society. Measuring height and crown spread, before they come down, I use this. A Wild Heerbrugg T1A double repeating theodolite. Made in 1959 in Switzerland it's extremely accurate. 30 X telescope. I also use it to lay out building foundations. Requires no batteries and neither does a slide rule.

I used a setup very similar to that working for the Oklahoma Geological Survey in 2010. You can see some of the places I used one of these devices (in stunning detail) here: Photosysnth - Photosynth

Now that is a gadget that I could easily fall in love with!

If they're champions why they coming down? And how do you measure them?

 

[Timberframed]

Due to mostly their age. Better to bring them down before they fall on their own. It's the way it is. Nothing lasts forever... Optical micrometers and trigonometry. Nothing more nothing less.

It's only a hazard tree if it threatens a human use area or human used utility. Roads, trails, powerlines, buidlings, houses, etc.

So, what do they threaten?

They threaten just what you mentioned. From Fairmount park to Abington Friends to several Arboretums in the area. They get big as they age and become dangerous as you have people walking around undreneath. Who here doesn't know this?
Steven, How about John McPhee's "Annals Of The Former World"?

So they threaten all the things I mentioned? That's either a sweeping generalization or a target rich area. Sure is crowded back East.

And how are we supposed to know what they threaten? After all, your thread is about A Wild Heerbrugg T1A double repeating theodolite that was made in 1959 in Switzerland and it's extremely accurate. And that's all your picture shows.

Makes no sense to measure a tree before it gets cut down, especially using the hobbyist method of "Champion Trees". Now standing timber, on the other hand...

Plenty of us know that big trees die. However you came in here blathering about some Swiss made equipment with a vague quip about "champion trees coming down." Be a little more specific next time. Who here doesn't know that?

Blathering

Didn't mean to blather. Oh well ya can't share without gettin' hit on the head...Whatever...

Better than what usually goes on in this forum which is nothing. I was interested....

You guys almost made me laugh my drink out through my nose. You two aren't brothers by any chance are you?

Yeah, don't know why poor old Timberframed got jumped on. Perhaps someone was having a bad day? I have now oficially fallen in lust with the Theodolite gadget!

It's all good. My fault for blathering. I got into measuring trees after I noticed a juvenile Tulip Poplar on my property grew 6' taller in one Summer from 13' to 19'. That tree is now shading the front of the house at 42 1/2'. Can't do a tape drop.

Wow. I guess it would be pretty neat to watch them grow that tall. I've never really lived anywhere long enough to watch any grow that much. You can blather away.

C'mon
rent a helicopter and measure it!
