How does a Surveyor Draft a Street Corner?
How does a Surveyor Draft a Street Corner?
(OP)
Hello,
My background is as an engineer and drafter, not a surveyor. Therefore:
When a suveyor is hired to plot the building perimeter and curbline of a building located on the corner of a street intersection, how many points along the curb corner does he document?
For this question I'm envisioning a typical street corner, where the curbline is rounded from street to perpendicular street. I believe this is called the curb radius?
I'm trying to understand how the surveyor drafts the curbline in CAD. I know he doesn't collect an infinite amount of points along the curve of the curb corner. I'm therefore wondering if he merely documents the point of tangency on each street, and then a third point somewhere at the seeming max point of the arc? Then in CAD he could connect those three points with an arc that runs through them all.
Sincerely,
Brian

To add, the intersecting streets are both curved, with one side of the street using an arc and the other street is a spline. I will be giving them a call Monday to clarify.
How come you are asking this question? I generally talk cars with my old boss, but I am sure he would be happy to school me on surveying questions. =)

"Top of curb shots are generally taken at angle points, direction changes and points along a curve. Sometimes they are drawn with a radius and sometimes with a spline. Most of the time with a serpentine planter area they will take several shots and draw a spline; otherwise, we would have to take way too many shots."
