LaoPo Posted January 12, 2013 Share Posted January 12, 2013 (edited) The easiest way to measure the height of the tree or anything else for that matter is simple, you need a stick, hold your arm straight out in front of you with the fings extended now measure the distance from your eye to the end of your fingers that is the length of your stick, now hold the stick apprx in the middle at arms length and walk backwards until the top and bottom of the tree are level with the top and bottom of your stick so measure the distance back to the base of the tree, the measurement is very accurate. There is another method using a shorter stick but you need a helper but still very simple. Or, make a home made clinometer, sort of like a protractor with a movable pointer. Measure the angle to the top of the tree. Measure the distance across the river to the tree on google earth. Then use a bit of trigonometry to work out the height. Better rent-a-monkey. 1. Make sure you know how heavy the monkey is 2. send him to the top of the tree 3. tell him to jump down 4. make sure you have your stopwatch ready; a speedometer is also OK 5. divide the milli-seconds versus the Kg weight of the monkey when he lands, and: Sim-Sala-Bim: now you know the exact height of the tree !

chokrai Posted January 12, 2013 Share Posted January 12, 2013 It would look higher if you cut the grass really short around the trunk. Link to comment Share on other sites More sharing options...
Paagai Posted January 12, 2013 Share Posted January 12, 2013 Must be a slow Saturday, can't believe I've just read this thread The OP should start a website : ratemytree.com People can post pictures of their trees and viewers rate them. Well, it seems popular on a site with a similar name specializing in measurements of length and girth and there's no need to use trigonometry........sorry, let's not go there Link to comment Share on other sites More sharing options...

tombkk Posted January 12, 2013 Share Posted January 12, 2013 You can also have someone put a mirror at the top of the tree. Then, you shoot a shot flash of light up from the ground to the mirror, which will refelct it back to the ground where you will have an optical sensor. You measure the time the light takes for the round trip, and since the speed of light is known, you have the distance, i.e. height of the tree. (Don't forget to divide by two.) Since (in principle) is how they measure the distance to the moon, so it is a proven method. Link to comment Share on other sites More sharing options...

harrry Posted January 12, 2013 Share Posted January 12, 2013 Homepro has laser height measurin things. Yep you climb the tree with one...drop it and see how long it takes to reach the ground. If you fall out of the tree at the same time you should hit the ground together. Link to comment Share on other sites More sharing options...

Well, maybe you could keep the monkey on a leash, since otherwise you not gonna see the animal ever again anyway, and when he's at the top just measure the leash. 1 Link to comment Share on other sites More sharing options...

xen Posted January 12, 2013 Share Posted January 12, 2013 Most arbourists will use the method with an clinometer to measure the angle then using sine/cos tangents to calculate the height . There are now clinometers that do the calculation for you. It is also possible to calculate the height by measuring the shadow and then using solar charts for the location to find the height . I can't remember anything more about that because it was too long ago i learnt the method , Nowdays when i need to get an appropiate height i just count the metres up the tree and that gets a ball park figure that is usually pretty close. Metres are much easier to count and then do a conversion if it is needed in feet but that is rare. Link to comment Share on other sites More sharing options...
NeverSure Posted January 12, 2013 Share Posted January 12, 2013 (edited) Measuring the height of a tree is just too easy. I am getting some chuckles here. I had to measure the height of more than 100 trees one day for logging/value purposes. Get a stick of known length. I like a yard stick (meter stick???) but anything will do. In mid morning or afternoon, put the stick vertically on the ground and measure the length of its shadow. Now you have a ratio of stick height to shadow length. Now measure the length of the tree's shadow and apply the ratio and presto - you know how tall the tree is.

harrry Posted January 12, 2013 Share Posted January 12, 2013 If you climb the tree and put a bunch of bananas on top the monkey will swim the river and climb the tree itself then you just have to make faces at it and measure the time for the banana skins he throws at you to hit the ground. 1 Link to comment Share on other sites More sharing options...
Tywais Posted January 12, 2013 Share Posted January 12, 2013 There is another method using a shorter stick but you need a helper but still very simple. If you have an Android phone with camera there is an app that can be used to measure heights and distance. Smart Measure Apple probably has a similar app. Link to comment Share on other sites More sharing options...

kaptainrob Posted January 13, 2013 Author Share Posted January 13, 2013 Seems this thread has grown legs and run a long long way plenty of laughs to be had as well. But ... who owns the tree and the magnificent property it stands on? Google shows 3 or 4 ingress roads in a questionable state of repair, no apparent grand entrance gate and no signs. Google street view of possible entry, click here. Might have to go for a drive .... Link to comment Share on other sites More sharing options...
Thai Dreamer Posted January 13, 2013 Share Posted January 13, 2013 It is a lovely home as well, not just the tree. I have often wondered how much that would go for at a public auction. It sure would beat my shack !!!! Link to comment Share on other sites More sharing options...
eyecatcher Posted January 13, 2013 Share Posted January 13, 2013 I may be completely wrong but there is a big house on the same side/vicinity owned by the Crown Prince of Thailand....but that one may be a little further away from the new sluice construction. you would know the one if you saw it.

You are correct. HRH house is at least ~750m south of the subject house/tree. There's a large, gated, park-like area just south of the flood-gate construction site and a rutted dirt road passes it, heading south. Beyond that, the Google Map (GM) location (posted above), appears to be a service entrance to that property. Actual road entry being from the south, along the river ... GM doesn't show it, and ends at a big gate with dogs lying on the road. Pics later. Link to comment Share on other sites More sharing options...
