| Oct 7, 2014 at 15:03 | comment | added | Thanasis | @underdark The 6 areas do not have the same cover (how do you call the result of the multiplication of width x length? - I am not a native English speaker). I want to create a surface size that would be the same for all of them, by using a polygon with the same surface cover but different shape (rectangle or square). That is why I called it 'average'. (not based on the exact features of the map in each area). Your suggestion for custom grid is ok, but the mkgrid and other stuff that I tried are causing an error. That is why I would like full instructions / paths to reproduce it in QGIS. | |
| Oct 7, 2014 at 12:01 | comment | added | underdark | I'm still uncertain what rules should be applied to "find an average square or rectangle area surface"? For the fishnet solutions, wouldn't it be enough to generate a grid and move it to your desired location manually? Or does it need to be some kind of automatic process? | |

| Oct 6, 2014 at 16:55 | comment | added | Thanasis | I would like to have the same area surface for all of my study areas (some are streets and some square-like). So depending on how my areas look like, I need them to have let's say 6000sqm, either in square or rectangle shape. And then create the buffer zones based on them. I do not know if it is easier to make the main polygon for each area based on a single point or create a polygon and adjust it to my area. Thank you. | |
