it is always been easy but due to bad faculty i was not able to understand the basics and levelling become nightmare for me finally now i can say loudly give me autolevel i want to do levelling ....TODD HORTON SIR U ROCKS .....RESPECT FOR YOUR WORK FROM INDIA...
I just have to tell you, these videos have really been so helpful to me! I'm in school on my way to becoming a surveyor and every time I get my math wrong or get frustrated, I turn on one of these videos to relax my mind. It's become a nice review and a soothing ritual. Thanks for taking the time to make these!
I have enjoyed your videos they were fun to watch and you touched on rocking the rod a very important part of eliminating some error.... I studied under one of the best surveyors in the country not in the classroom but in the field.. we once ran a bench Loop 3 miles long with permanent turn points.. I read one way he read the other...250' to 300' turns...closed at .02.... He remarked as unheard of... we rocked each turn.. and he chose to hold the first run outright... I'm hoping you'll do another video showing stadia.. meaning retrieving Distance by using the method of elevation... And also running a three wire or even two wire bench Loop.. and meaning out the values... Which I have used multiple times... Thank you Todd for the videos I have enjoyed them I already know how to perform these techniques .. and as I said before when I started I wish I had RU-vid..lol..
Thank you so much for the clear and concise tutorials. As someone new to the whole aspect of precision leveling as it relates to the building industry, I wanted to thank you for your time in producing such a great video series. I wish more instructional videos were as professionally done. Hat off to you sir!
Thank you, excellent tutorial. These devices are becoming cheap and readily available to the DIY crowd due to electronic/laser devices, so a good solid fundamental tutorial in the basic usage is valuable.
I am just waiting for the video about using all three stadia to compensate for the "lean" of the "Philly Rods". Plus once we are done with leveling radial survey will be mind bending.
1/100 of a foot. But long distances. I was once amazed when one of our products had to be leveled to a tiny fraction of an inch and it was done with a leveling telescope. The target was roughly 10 ft in diameter and the. telescope was some 15 to 20 ft from the closest edge. There were 4 pedestals for the scale rod, 3 of which were visible to the telescope. And yes, despite my reservations, the process produced resolutions to 0.001 inch. I don’t remember what the leveling specification was, but probably something like 0.005 or 0.010 inches. The adjustment was done with 3 of 4 jack screws. This procedure was a demonstration of the capability at our plant. The customer eventually performed the same at their plant and supposedly locked all the jack screws .
