地图不会显示建筑物号码（tileMill + OSM）

问题描述

我正在使用tileMill为我的iPhone应用程序创建脱机地图，长篇小说 - 我已从）我找不到包含房屋号码的图层。

设置房屋号码标签的代码：

  #housenumbers { 
 [zoom> = 17] {
 text-name：[addr：housenumber]; 
文本放置：内部; 
 text-min-distance：1; 
 text-wrap-width：0; 
 text-face-name：@ book-fonts; 
文字填写：＃444; 
 text-size：9; 
} 
} 
 
 #housenames {
 [zoom> = 17] {
 text-name：[addr：housename]; 
文本放置：内部; 
 text-wrap-width：20; 
 text-face-name：@ book-fonts; 
 text-size：8; 
文字填写：＃444; 
 [zoom> = 18] {
 text-size：9; 
} 
} 
} 
  

解决方案

您需要了解，OSM.org使用一个名为的纯渲染引擎。 是通过简化样式表来围绕Mapnik的包装。

如@scai所言，您需要创建一个样式表，为样式表提供标签。我不熟悉瓷砖，告诉你需要做什么，但通常这包括

• 添加标签符号addr：housenumber = *标签，并以适当的字体和大小打印值


• （创建处理建筑物轮廓等内标签位置的假节点）

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 link) is showing building numbers as you can see in picture:

but after importing data, that i've download, to tile mill there's no building numbers:

any idea why this is happening? Thanks!

EDIT: I figure out how to set up house numbers label, but when i'm importing data to tilemill (with this tutorial) i can't find layer that contains house numbers.

Code for setting label for house numbers:

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

#housenames {
  [zoom >= 17] {
    text-name: "[addr:housename]";
    text-placement: interior;
    text-wrap-width: 20;
    text-face-name: @book-fonts;
    text-size: 8;
    text-fill: #444;
    [zoom >= 18] {
      text-size: 9;
    }
  }
}

解决方案

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.)
