I have a line and a point layer. The points are on a line(spline) I want to know the coordinates of 50 meters ahead based on a specific point. And I want to know the coordinates of 50 meters in the rear. I want to enter two coordinates into a table of points.(I have hundreds of them!) I have to solve it with QGIS or arcmap Python, but I have not found a way
- I created a buffer based on a point and then clipped it.
- I got both ends of the clipline, but it is not the exact length.
