Description

I have been attempting to render cities' boundaries (referred as 'administrative boundaries' in osm) in tilemill (using the osm-bright stylesheet) using the default style of osm2pgsql and osm-bright.

osm2pgsql's default stylesheet treats the tag admin-level with the data type 'text' (see https://github.com/openstreetmap/osm2pgsql/blob/master/default.style#L35 )

Currently, osm-bright's base.mss treats the admin-level field as a numerical, 'float' flavor. When a user is importing osm data into osm-bright via osm2pgsql, no administrative boundaries will be displayed.

To fix this, simply change admin[admin_level=2] to admin[admin_level='2'] in base.mss

Pull request was removed because there still may be conflicts with imposm.

Research direction

Start with osm-bright/base.mss and compare the admin_level filter with osm2pgsql's default.style. Check the issue's noted imposm compatibility concern before testing the proposed filter form. Done means administrative boundaries render for osm2pgsql imports without breaking the other import path.
