I have a vector layer with points denoting receptors. I have a second vector layer (polygon) delineating a site boundary. Utilizing QGIS v2.14, I am looking for a method to get the orientation of the points to the polygon. I.e. in degrees what is the orientation of each point to the site boundary polygon.

  • If you want the orientation in degrees, wouldn't it make more sense to add that as an attribute to the point layer? – csk Mar 28 '17 at 14:19
  • What GIS software are you using? What have you tried? – PolyGeo Mar 28 '17 at 20:13
  • Hi, I'm utlising QGIS 2.14. The query relates to having multiple points, but looking to get QGIS to supply an orientation to a polyline. Thereby improving accuracy of results. If this can be added to the points table through the field calculator, all the better. – K Goodwin Mar 29 '17 at 14:25

    @KGoodwin It's not clear if the orientation is towards a polygon (as in the original question) or a polyline (as in your last comment). Then, it would be enough evaluating the orientation towards the centroid of the polygon/polyline? – mgri Mar 29 '17 at 14:37
  • Sorry, the orientation is towards a polygon vector layer. Your solution sounds good, but unfortunately I don't know how to go about doing it. – K Goodwin Mar 29 '17 at 16:10
