ポリラインを取得したい複雑なルート URL と埋め込み URL があります。それらをポリラインなどに変換できたら、最終的な形式である GeoJSON に変換できます。

私は API を調べましたが、PB を受け入れたりデコードしたりするものは見つかりませんでした (これは何ですか? プロトコル バッファではありません)。これまでのところ、これは私が持っている限りです：

//php
$pb_array = explode('!', $pb);
foreach($pb_array as $key => $value){
    echo "$key - $value<br/>";
}

私が見つけることができる最も近いヒントは、このスレッドからのものです。私は探し続けますが、私は立ち往生しています。

これらの URL のいずれかを入力し、GeoJSON を返す API ベースのソリューションを作成しようとしています。

さて、これが私のずさんなしかし実用的な解決策です。私のニーズにはGeoJSONが必要でしたが、緯度/経度配列を取得したら、他の人はGoogleマップサービスを使用して目的の出力を取得できます.
