Mapping question

[andrej.ros...@unister.de]

Hi,

a newbie question, probably, still it bothers me for a while. May be someone can give me an easy answer.
I am trying to import islands, if possible including the wikipedia tag, as example data set I downloaded Spain (http://download.geofabrik.de/europe/spain-latest.osm.bz2). For the import I use the following mapping (stripped of comments):

from imposm.mapping import (
    Options,
    Points, LineStrings, Polygons,
    String, Bool, Integer, OneOfInt,
    set_default_name_type, LocalizedName,
    WayZOrder, ZOrder, Direction,
    GeneralizedTable, UnionView,
    PseudoArea, meter_to_mapunit, sqr_meter_to_mapunit,
)

db_conf = Options(
    # db='osm',
    host='localhost',
    port=whatever,
    user='osm',
    password='osm',
    sslmode='allow',
    prefix='test_',
    proj='epsg:900913',
)

island = Polygons (
    name='island',
    fields = (
        ('admin_level', Integer()),
    ('wikipedia', String()),
    ('name', Name()),
    ('boundary', String())
    ),
    mapping = {
    'place' : (
        'island',
        'islet',
    ),
})

What I am wondering: the data contains a relation for Mallorca (id 374056, with tag place = island), but the polygon is not imported. Am I doing something wrong or is there a simple explanation for this?

Thanks!
Andrej

Andrej,

Check that all the ways referenced by the relation are also present in the extract. If not, the geometry is most certainly invalid and is not imported by imposm (you should get a warning message on your imposm output when that happens).
