What would you like to see? I wish I had more time to focus on this but I don’t. I also train new people so videos are simple. Ironically setting up over a known point is the #1 thing I see.
4:02 Don't you have to enter the instrument height and reflector height? Where do those points shown on the tablet beforehand come from? I.e. point 1 (station), point 5 (backsight), and the others? Thanks
First, you have to name a point, input any coordinates, such as Eastern 500, Northern 700, could be any numbers. next you point the instrument at any direction, if you set the direction to 0 degree horizontal, it will treat that direction as north. then you shoot any point, every point will be showing on the map as a known point with coordinates. The key is to tell the machine where is the north at first. I am going to make a video to show how to use a total station, and what a total station can do. Actually, it is simple, any total station only measure 3 things, horizontal angle, Vertical angle and slope distances. anything else is based on these 3 numbers to to the calculations.
Understood. But why is he not entering the instrument and target reflector height? Even if not concerned about elevations, seems horizontal calculations would be off if missing vertical heights such instrument and reflector height when triangulating?
@@timd9430 without the instrument and target height, you can still calculate right coordinates, cause you only need horizontal distances and horizontal angles to calculate, the distances were automatically converted to horizontal distances by total station itself or by data collector with the vertical angle. vertical angle is automatically acquired, because there is a plumbing zero point to the center of gravity all the time as long as the machine is leveled. Horizontal distances between target and instrument has nothing to do with their height, only vertical angle matters.
