Hey listers.
We have built centerlines for several of our communities that are
extremely accurate (we split the lines strategically so that addresses
geocode very close to their actual location). One of the things that
we have had to do to get these centerlines to work correctly is put the
same address on both the TO of one arc as the FROM of the next arc:
1--------------9()9-------------19
This goes against what we have found to be the general convention:
1--------------9()11------------19
We have dicovered that some applications cannot use our centerlines.
We will be fixing our centerlines but I would like to pose the question
to the list of the correct way to model a centerline. Our centerline
ensures that the point for the address of "9" is located at a different
real location than the address of "11". I realize that this is
technically considered overlap. Anyone have some input on this?
