[talk-ph] RFC - Proposed mapping guidelines for roads (classifications, names)

[Jherome Miguel]

For names, I agree there is a problem. Posted road name can be inconsistent
across different jurisdictions or even within the same jurisdiction. That’s
the reason we need to review how we map street names (we rely too much on
road signs). There’s a lot of instances the road signs omit suffixes
(especially “Street/St”) while the addresses use the full name. We seem to
forget a road’s name= is also used for addr:street=.

The main point behind the proposed guidelines is to better align PH
practice with global tagging practices. We have a road classification
system that  is too watered down and is somewhat only appropriate to urban
areas. Our practice on naming roads had rather preferred short names to
reduce clutter and deter mappers who abbreviate them, but that somewhat
raises issues about mapping for the renderer (whether to keep, abbreviate
or remove street name affixes is up to them), plus, we’ve got into the
problem of relying too much on street signs, forgetting some roads have no
names posted on any official road sign and the name verifiable from asking
locals or finding posted addresses, and addresses posted on business signs
(or even their ads, business cards and things) should be used as sources as
well.
