I have a line which represents a cross section. I have the coordinates of on its starting point. I need the coordinates of the end point of that cross section line. The distance between these two points is known. Is there some way to calculate it, or do I need some more information?
I want to calculate the unknown coordinates of end point $B (x_2,y_2)$ on a line with given distance from a known coordinates of starting point $A(x_1,x_2)$.
I have a cross section line AB with length of $2800$m. The start point $A(x_1,y_1,z_1)$ is known. $z_1$ is the bed elevation on point $A$. I need to calculate the coordinates at end point $B(x_2,y_2)$. Now there are two situations.
- Case 1: I have $z_2$ at point $B$ with me also.
- Case 2: I don't have $z_2$ on point $B$ with me.
