Map won't show building numbers (tileMill + OSM)

Question

i\'m using tileMill for creating offline map for my iPhone app, long story short - i\'ve downloaded OSM data for Ukraine region from here. I\'ve checked that online map(from

Answer 1

for me it worked with planet_osm_point instead of planet_osm_polygon

( SELECT way, "addr:housenumber" FROM planet_osm_polygon WHERE "addr:housenumber" IS NOT NULL ) AS data

Answer 2

Layer

Source: PostGIS

Table or subquery

( SELECT way, "addr:housenumber" 
  FROM planet_osm_polygon
  WHERE  "addr:housenumber"  IS NOT NULL
) AS data

Styling

label.mss

#housenumbers[zoom >= 17] {
  ::label {
    text-name: '[addr:housenumber]';
    text-face-name:@sans;
    text-size: 9;   
    text-placement:interior;
    text-min-distance: 1;
    text-wrap-width: 0;
    text-fill: #444;
  }    
}

"::label" is needed for prevent red points on the map.

p.s. for russians, I wrote about it in my blog.

You need to understand, that OSM.org uses a pure rendering engine called Mapnik. Tilemill is a wrapper around Mapnik by simplifying stylesheets.

As @scai say, you need to create a stylesheet that renders a label for housenumbers. I'm not familar with tilemill to tell you what need to be done, but usually this consist of

• Adding a label symbolizer that looksup the addr:housenumber=* tag and prints the value in a appropriate font and size
• (creating fake nodes that deal with the placement of that labels within building outlines etc.)
