The whole thing as one line. The separation of the two groupings is due to the fact that they represent property corners along the right-of-way of two different blocks. The goal is to compare the calculated best fit line on one side of the street with points on the opposite side. This is done by using a perpendicular offset routine to those points. We then compare the right-of-way width of the located (what's in the ground) points with the recorded plat (map) right-of-way width.
