Often, the only clue the line is there is the pylons. Any time the line changes direction there MUST be a pylon. It's possible to miss a pylon or two along the way of a power line if the line itself is visoble. The pylons are separated by large distances. Tree rows are different. One-dimensional woods. It might be possible to map individual trees, but it would be tedious. Trying to map individual trees algorithmically by giving a typical spacing would give misleading results and put more load on the renderer. Tree rows are a shorthand for tediously mapping a lot of individual trees. I see individual trees and tree rows as alternative ways of dealing with things and plotting individual trees on a tree row seems bizarre (a row of individual trees is obviously a tree row, there's no need to map both at the same time). -- Paul
