I am trying to make a map of a property fenceline based on a survey which gives precise bearings and distances between landmarks. Following recommendations in Creating points based on distance and bearing from survey point using QGIS?, I used a CSV file to turn distance & bearing values into x- and y-offset values.
Now I want to know how to translate those offsets into actual coordinates.
My file contains X and Y shift values — that is to say, the values for any given point are not X and Y coordinates, but rather Delta-X and Delta-Y values relative to the point before it.
Given the coordinates of the initial point, one may solve for the coordinates of all other points in the polygon by evaluating their offsets from that initial coordinate point.
How can I write a script that will give me the actual coordinates of the points in my polygon?
