I toyed with that idea when I first started tracing them, but theres two things to consider. Main lines are generally tagged as power=line whereas suburban lines are tagged as power=minor_line. Main lines generally use towers and cross large areas of land, where minor lines often cross through areas already full of street data. Ive been tagging all nodes as power=tower where its evident from nearmap that there is a large metal tower, however rendered tiles only show the power=tower nodes, not the power=pylon nodes. I figured I was best off doing the line tracing then if renderers support it at a later date, its not too difficult to change the node to power=pylon. When I create the ways, I go from pylon to pylon, with no in-between nodes, so can depend on every node that isnt labelled as power=tower being a pylon. I havent seen many power lines drawn for Australia, but since they are relatively easy to trace on nearmap and can be useful when shown on maps at high zoom levels, I figured Id trace them in. Ive also traced a large number of powerlines from the Shepparton Nearmap, using the same method described above.
