In essence the particular problem posed was to determine how much roadside space was available for tree planting within the London Borough of Barnet. JR will outline the rationale and challenges behind planting in urban areas. Several factors are considered here, one being determination of the width of the roadside space.  DP will outline the steps used in applying the built-in algorithms in QGIS to classify the roadside space into different widths without using any complex maths or programming!  It will demonstrate how the graphical modeller was used to automate the repetitive tasks and how the problem was broken down in to smaller chunks to deal with quite a large dataset.
