Hello everybody!
From time to time I use mkgmap for producing Garmin maps for myself. Recently I
needed to have a possibility for an entity to get the name of the place where
the entity resides, just like it's the case with boundaries and admin levels.
The purpose for me was to have easier address search and displaying in Russia
where we have one particular region type with admin_level=6, that is named
"городской округ" (city district). It's often the case that it contains only
one city but the cities themselves are not being mapped as admin_level=x. So in
my style, to fill mkgmap:city in these cases, I only can use the value of
mkgmap:admin_leve6. But that official name can be quite long and unhandy, and
the "normal" name of the city cannot be figured out automatically.
For example:
городской округ Жуковский => Жуковский
Челябинский городской округ => Челябинск
Зиминское городское муниципальное образование => Зима
Somehow I overlooked WanMil's message from 2013
(http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2013q2/018003.html) and so I did
the change myself in a local branch. Now I can write in my address style
include something like this:
# Russia
mkgmap:country=RUS & mkgmap:city!=* & mkgmap:admin_level8=* { set
mkgmap:city='${mkgmap:admin_level8}' }
mkgmap:country=RUS & mkgmap:city!=* & (mkgmap:place=city | mkgmap:place=town) {
set mkgmap:city='${mkgmap:place_name}' }
mkgmap:country=RUS & mkgmap:city!=* & mkgmap:admin_level6=* { set
mkgmap:city='${mkgmap:admin_level6}' }
and get the proper city name in my map. Of course, to get this working, I had
to create my own set of precompiled bounds with additional rule
"type=multipolygon and place= and name=" for osmfilter and a run of
BoundaryPreprocessor to set the variables mkgmap:place (attribute 'place' from
the multipolygon) and mkgmap:place_name (attribute 'name' from the
multipolygon).
I don't know if it's a highly desirable feature, but probably someone else will
find it useful and it could be added to a new release of mkgmap.
Cheers!
Max
