地図のスタイリングをブラウザ上で行う**「Mapbox Studio」**にComponentという、これまで以上に簡単に地図のスタイリングができる機能が実装されました。
12月14日時点では、β版としての提供であるが、早速使ってみましたので、簡単に紹介します。
#Step 1
##Mapboxのアカウントをとります
まだ、Mapboxのアカウントを取っていない人は、まずアカウントを取得してください。無償です。
##Studioのページを開きます
ログインして、こちらのページに行きます。
New styleをクリックすると、テンプレートを選ぶ画面がでます。
ここでは、Basicを選択して、Customize Basicをクリックします。
これで、Step 1は終わりです。
#Step 2
##ComponentsとLayersという2種類のビュー
ComponentsはLayersをラベル系、道路系などの類持続性毎にグループ分けしたものです。
Componentsの中身を見るには、Layersタブをクリックします。
####Componentsビュー
ラベル系、道路系などのかたまり毎のスタイリングを設定できます。
####Layersビュー
個々のレイヤーに対して、スタイルの設定ができます。
今までは、Layersを一つ一つスタイリングする必要があり、手間がかかりました。Componentsを使うと、グループ単位でスタイリングでき、短時間でスタイリングを行えます。また、jsonコードを意識すること無くできるため、コーディングの経験の無い人も心配ありません。
#Step 3
##さっそくやってみよう
####まずはベースの色を変えます
初期設定では、ベースの色が茶色になっています。一般的に、ベースの色を明るめにしてしまうと、主題となる情報を視覚的に際立たせることが難しくなります。そこで、ここでは落ち着いた色に変えてみます。
####グレーに変えてみる
ベースの色をグレーに変えます。Componentの特長として、ベースの色に連動して建物の色も変化します。
道路の色は白にします。
####POIラベルの日本語表示など
言語を日本語にします。
POIのカテゴリー毎に、表示の密度を調整します。
スライドバーを動かすことで、ラベルの密度を設定する値が変化します。
####歩行者道路の表示
初期設定では、公園内などの歩行者道路が標示されません。そこで、表示をするように設定します。
Before
After（皇居外苑が改善されています）
他にも、水の色や緑地公園の色、学校の色、病院の色などを調整します。
だんだん、日本の地図っぽくなって来ました。このままでも良いのですが、もう少し手を入れてみます。
####首都高の色を変える
道路がすべて白になっていますが、首都高の色だけを目立たせたいと思います。
道路はComponentsでは一つのグループとなっていて、高速道路の色だけを別にする場合は、Componentsの機能では不可能です。
そこで、Layersタブをクリックして、首都高が入っているLayer(rad-motorway-trunk)を調整します。「Set manual override」をクリックし色を調整します。
間違って、変な色になってしまった場合も、revertを押すことでもとの色に戻すことができます。
####マップをPublishする
今まで設定したスタイリングは、自動的に保存されますが、他の環境からは見ることができません。
そろそろここで、マップをPublishしてみます。
ブラウザ画面右上の「Publish」を押すと、確認画面がでます。左がBefore、右がAfterです。
Publishしたマップは、Webブラウザの他、iOSアプリとして提供されているMapboxのStudioPreviewでiPhoneで見ることもできます。
####建物を3D表示にする
建物高さのデータが属性データとして入っていれば、その建物を3D表示にできます。これは、Componentsの機能として、トグルスイッチを切り替えるだけで実現します。
Before
After
ぐっと東京の街中っぽくなってきました。
3D表示はインパクトがありますが、主題に対して目立ちすぎる時があります。用途に応じて使い分けましょう。
####iOSのStudioPreviewでの表示
####実は海外でも同じスタイルが適用されています
今回作成したスタイルは、世界中に適用されています。
これはシンガポールの例です。
自分が見慣れた表現で、世界中を見ることができます。
#今回作成したスタイル
今回作成したスタイルは、こちらのURLとなります。
皆様のMapboxアカウントで利用することができるはずです。
ただし、改変は私しかできない仕組みのようです。
#ソースコード
最後に、今回のスタイリングのソースコードになります。
もし、改変したいのであれば、このソースコードを編集して下さい。
また、githubのリポジトリはこちらになります。

5657行にもなる、長いjsonファイルです。エディタで個々に設定していたら気が狂いそうですね。。
Mapbox StudioのようなGUIツールがあることで、私たちはとても助かっています。
