I would like to obtain a table containing all the coordinates of the triangles in the following image.

enter image description here

I know it is possible to georeference my map using the georeferencing plugin and then I can access the coordinates of any point using the Copy_Coords plugin. But this takes much time and I would like to know if you know a way to do it faster ?

    If possibly I would try to get the data from the source owner.... – Jakob Oct 18 '15 at 20:36
  • I back @Jakob suggestion. I can see overlapping markers in dense areas so these aren't going to be easy to convert... find out who owns the data and ask for a clip - it's the only way to be sure you have complete and accurate data. – Michael Stimson Oct 19 '15 at 1:27

You can use unsupervised classification methods; But it is too much hassle to recommend it

  • Can you expand on why it's too much hassle... you and I both know that it's not sutable but for future readers contemplating it it would be good to give an outline of the methodology showing why it's shouldn't be considered; also, in a slightly different case it might be workable and totally worth the effort. – Michael Stimson Oct 19 '15 at 1:25
