google-maps - 谷歌地图导航符号

Question

我正在寻找一份详尽的谷歌地图导航标记列表。

为避免混淆，我不是在寻找这个。

我正在寻找导航标记的完整列表，例如左转、右转、回旋处、左叉、右叉、微左、微右等。

我知道文本表示会有一些变量，比如 Roundabout 3rd exit。这可以是第一个出口或第二个出口等。但我希望从中提取 Roundabout 并将该指令的可变部分放在一边。为此，我需要一个完整的标记列表。

我搜索了很多，但我只能找到像酒吧、高尔夫球场等感兴趣的地方的标记。

提前致谢 ：）

编辑：进一步阐明我的要求：Google Maps API包含“html_instructions”标签。我想将图像分配给尽可能多的不同指令。为此，我需要确定一份详尽的驾驶说明清单。

Answer 1

如果我正确理解了您的问题，则可以在此 url的下图中找到完整列表（以视觉形式） 。我找不到翻译列表，但这无论如何都会是语言无关的。

Answer 2

正如@edb 在他的回答中所建议的那样，文本取决于语言和地区。因为，我不需要在我的项目中处理本地化，所以我编制了一份英文说明列表。可以从@edb 的答案中使用相应的方向符号。

方向命令

• 采取<nth> <left | 对>
• 转<向左| 对> [<在……> | <到……>]
• 退出到<...>
• 从 [...] 出口驶向 <...>
• 在环岛，<继续直行| 走第 <n> 个出口>
• 左转合并到 <...>
• 采取坡道<在<左| 右> 上... | 到……>
• 合并到 <...>
• 保持 <左 | 右>在岔路口[继续朝……]
• 轻微 <左 | 右> [上...]
• 夏普 <左 | 右>在<...>;
• 在 <...> 处掉头；

一些没有关联符号的指令。

• 继续……</li>
• 头<朝着……，向北，向南，……>
• 路过<...>

希望这会有所帮助:)

我没有找到任何官方的东西，所以我做了一个快速的 C# 程序来提取关键短语。

输出在这里：

我的代码是：

static void Main(string[] args)

    ConcurrentDictionary<string,int> phrases = new ConcurrentDictionary<string,int>();

    List<string> citiesOfUS = new List<string>()

    };

    Parallel.ForEach(citiesOfUS, (string origin) =>
    {
        foreach (string destination in citiesOfUS)
        {
            string json = new WebClient().DownloadString("http://maps.googleapis.com/maps/api/directions/xml?origin=" + origin + "&destination=" + destination + "&sensor=false");

            bool shouldExitLoop = false;

            while (!shouldExitLoop)
            {
                int pos1 = json.IndexOf("<html_instructions>");
                if (pos1 == -1) { shouldExitLoop = true; break; }

                int pos2 = json.IndexOf("</html_instructions>");
                if (pos2 == -1) { shouldExitLoop = true; break; }

                string subString = json.Substring(pos1 + 19, pos2 - pos1 - 19);

                json = json.Substring(pos2 + 20);

                int posB1 = subString.IndexOf("&lt;b");

                while (posB1 != -1)
                {
                    int posB2 = subString.IndexOf("&lt;/b");

                    string part1 = subString.Substring(0, posB1);
                    string part2 = subString.Substring(posB2 + 6);

                    subString = part1 + " SYM " + part2;

                    posB1 = subString.IndexOf("&lt;b");
                }

                int posSpace = subString.IndexOf("&gt;");

                while (posSpace != -1)
                {
                    string part1 = subString.Substring(0, posSpace);
                    string part2 = subString.Substring(posSpace + 4);

                    subString = part1 + part2;

                    posSpace = subString.IndexOf("&gt;");
                }

                int posDiv1 = subString.IndexOf("&lt;div");

                while (posDiv1 != -1)
                {
                    int posDiv2 = subString.IndexOf("&lt;/div");

                    string part1 = subString.Substring(0, posDiv1);
                    string part2 = subString.Substring(posDiv2 + 8);

    });


    string[] lines = phrases.Keys.ToArray();

    Array.Sort(lines);

    System.IO.File.WriteAllLines(@"C:\Users\Xantix\Desktop\WriteLines.txt", lines);            

    return;
}

基本上，这些是您尝试从美国的每个首都到其他每个首都时得到的英语短语。

任何出现在粗体标签之间的东西都被替换为“SYM”这个词，比如左、右、街道名称等。

注意：我删除了出现在 html_instructions 内的 div 之间的内容，因此缺少诸如“部分收费公路”和“正在建设中直到 SomeDate”之类的内容。

随意修改我的代码以将其他城市添加到列表中或添加街道地址等。
