What that pattern immediately makes me think of is that people were working
within a grid cell, and just mapped the part of the highway within their
cell, and that the intervening cells have not yet been mapped. If the
spacing isn't the same as the TM grid, perhaps some folks are using a
different grid, perhaps something self-imposed. For instance, they might
map the area that shows in one screen at whatever zoom level they're using,
save their work, go off to dinner...
Is the faint mark on the imagery a mapped way of some sort, or is it the
actual highway image?
