- find polygon corner coordinates 1 answer
I'm attempting to measure the distance of a series of points from a smaller number of polygons. As a first step, I've changed the polygons into points along their border, via the
Vector> Geometry Tools> Extract Nodes
command. This gives me the following result, after I've manually deleted irrelevant borders.
It's now my intention to export these points' coordinates into R to do some rudimentary neighbor and distance calculations. But when I open the attribute table, all the points representing the borders of the separate regions share a single geographic coordinate (which appears to approximate the polygon's centroid, but that's a guess). It's like the following:
Is there a different way to convert a polygon's borders to points, and recover the points' coordinates themselves?
