I am sending a discussion we (me and IanHaylock) had before with Mike
Collinson (no talk-ph at that time) on tagging Barangays this in the
context of when we are planning to import the GNS data.
For your comments
Thanks for all the input. Here is a modified version of the script
with PPL mapping to village not town. As is, it also reads the entire
rp.txt file but only outputs DCG=ADM2 POIs. The resulting file, also
attached is exactly the same as the one you sent me but has an
addition 'is_in:state=' tag. I am very keen to get lots of 'is_in'
tags into the OSM database as it will make future searching much
easier. For example, if there is a critical mass of entries for
Aurora Province spread across the province, it will be possible to
work out the approximate bounds of the province and limit searches
there. That removes the need to have exact boundary data.
Do upload it if you think it is ready.
On the issue of PPL = village or barangay or locality, these are my thoughts.
I suggest we definitely do not use 'locality', that is really meant
for place names that do not coincide with any (current) population
Plus: Works worldwide. Minus: Not strictly valid in a Philippine context.
We'd need to get the OSMarender and Mapnik guys to add a render rule
for this. We could also ask for it to be added as a Map Features
value, but that is not strictly necessary. I'd guess the easiest
request would be to say, "please render this exactly the same as
If I was explaining what Barangay means, does this sound right? :-
place=barangay is specifically for Philippine use, though may be
applicable in other parts of the world like South America. At an
administrative level, a Province (= a state) is divided into
muncipalities. Each municipality is controlled by a local council and
has a mayor. A municipality is split into barangays, headed by
Barangay captains. In rural areas, these equate to villages. In urban
areas, these equate to suburbs often highly distinguishable on the
basis of social class. A rural muncipality, e.g. Donsol, may
therefore have a town, Donsol, split into 3 or 4 barangays and then to
It is important to mark them on OSM maps because they are used
extensively in every day navigation, information, politics etc. They
almost invariable equate to an obvious population centre (unlike
European wards). Street signs often show which barangay they are in.
Jeepneys and buses often show a barangays as destinations.
