+1 However, I would disagree that the top down approach results in a tidier and consistent model, the opposite usually occurs, and even messier than OSM, because resource limitations result in everything being thrown into the pot with little attempt at harmonization via an analysis then synthesis process ( repeating as required ). http://factmyth.com/analysis-and-synthesis-explained/ The talk tab on a Wikipedia page is far more informative than the actual page itself, and show how much process actually went into it: https://en.wikipedia.org/wiki/Talk:Ditch >... embodied the cultural assumptions of the people who created it +1 See https://en.wikipedia.org/wiki/Blind_men_and_an_elephant
