How to construct a table to lay out the "horizontal curve" on the ground?
The steps that follow the design of the horizontal alignment is to set up it on the ground. For this purpose a table that contains angles and distances is established to set up the curve on the ground. I have no idea how this process is performed on the C3D
Are you sure that a table like this is necessary. I have not seen a surveyor using this technique for curve layout in the last thirty years.
Thank you for the answer Steve.
Then how to lay out the horizontal curve on the ground?
Suppose you have a “total station” and you need to lay out horizontal curve then you need a table that contains angles and distances to be able to “fix” the points of the horizontal curve on the ground.
Is there other way in this case?
In modern survey the instrument is typically set up over a control point which can be in any convenient location. If the alignment information is supplied then the equipment has the ability to calculate the angles and distances to any point "on the fly." The only thing that the surveyor needs from me is an alignment and profile in xml format.
