Am I wrong in assuming that address ranges in StreetInfo and
similar tables are supposed to increase in the direction that the
street segment was digitized, or is there no rhyme or reason to
how this is done? In other words, does the line direction of a
street segment mean anything at all, or is it a data bug when I
find these sorts of streets?
I've got a section of a GDT table in Hartford, CT with the
streets digitized any old direction regardless of the address
range directions. I've also found this situation in old
StreetInfo and BLR files.
This is a real bugger if you have to do a street-side routing
problem, as it doubles the complexity of any software you'd write
to use these files, so I was wondering if it matters if I just
force all the street segments to go in the direction of the
address ranges (keeping the actual addresses on the correct
physical sides of the streets, of course).
