I need to find the width of many small hill like features. I have the base point on one side, but need to find the matching elevation point on the other side of the line and measure the distance between the two.
The data is a series of cross section Shapefile lines draped over las . Points are also Shapefiles
Is there a way to search the line to find the same elevation along the line as the base point?
Thanks
Deleted my original answer because I wasn't reading correctly (need more coffee).
Create a box with its lower left corner at your base point, make sure the top right point is far enough away to encompass the entire profile. Then use that to clip the profile line. The point where it dips below your original elevation will be clipped automatically.
The downside is that a situation where the base surface on the other side is slightly higher will not be found.
