on a block of downtown san francisco, there are two block-long lines labelled ‘address interpolation’. there aren’t many nodes along this block, but the ones that exist mostly have explicit addresses assigned.
these were created 14 years ago (potlatch 0.10f). what do they do, are they valuable to renderers or to the map itself?
Yes but when the end points have no house numbers tagged, the sole thing left is the information that one side of the street has even numbers and the other has odd numbers which is completely useless information.
