I would like to then use the hedgerows by bringing it into QGIS as a layer. I need to know what software to use and the method to make such a layer?
I would like to use a google earth image in Grass and do a supervised classification on it for the Wigan, Bolton, Manchester and Salford area (England) They join up as a square and it is in this area I need to identify where hedgerows are located if possible. I have access to QGIS, Grass and Arc. ( I could also use free to download software).
Does anyone know of a way to achieve this?
