I need to create a buffer around a point, witch has to be 1.3x bigger than the length of a given line.
I want to automate this process with graphical modeler or pyqgis. So the program should automatically read the line's length and create a buffer around this specific point.
This one process is going to repeat hundreds of times. I will try to explain here all the steps that must be followed when the software runs the process only once:
1) The user must manually create a line and a point ( different shapefines and different tables). The line has the attribute length on its table.
2) The program should read the length of the line (created on step one) and create a buffer (with the radius 1.3x bigger then the line lenght) around the point (also created on step one).
So, these 2 steps consist one process. For each process, the user will create a new point and a new line. The line is only there to work like a rule. And the point is there to give the position for the buffer.
