Mapped grid infrastructure from OpenStreetMap, whose coverage is excellent in some regions and sparse in others. Nothing shown here means nothing is mappednearby — not that the site is unconnected. Lines are matched on a segment’s midpoint, so a corridor passing directly overhead can be missed; this under-reports rather than invents.
