Question

我试图使用OSM's Atlas project以便能够以图形的形式在地球的街道和地图上“行走”，但是我在使用它时遇到了麻烦。该文档似乎有点稀缺。

似乎我需要.atlas文件，但是我不确定如何获取/生成它们。

我尝试从OpenStreetMap export函数下载文件。它似乎给我.osm文件。然后，我尝试使用osmconvert map.osm -o=map.osm.pbf将它们转换为.osm.pbf文件。然后，我尝试使用Atlas的CLI命令将.osm.pbf文件转换为.atlas文件：atlas pbf2atlas --countryName BGR map.osm.pbf。

这似乎不起作用，因为随后我尝试加载.atlas文件，但它引发了异常。

import org.openstreetmap.atlas.geography.atlas.Atlas;
import org.openstreetmap.atlas.geography.atlas.AtlasResourceLoader;
import org.openstreetmap.atlas.streaming.resource.File;

public class Main {
    public static void main(String[] args) {
        File atlasFile = new File("BGR_map.osm.atlas");
        Atlas atlas = new AtlasResourceLoader().load(atlasFile);
        atlas.nodes().forEach(System.out::println);
    }
}

我在Atlas存储库中找到了一些其他已经生成的.atlas文件进行测试，并且它们正常加载了此代码，因此看来我无法正确生成.atlas文件。我怎么做？我想打开OSM地图并将其区域作为.atlas文件获取，以便我可以通过代码对其进行浏览。

获取.atlas文件以与OSM Atlas一起使用
