PLATEAUのデータ全部処理する その１

# はじめに

もろもろ想定してたよりやることが増えたので、予定を変更してPLATEAUの話を書きます。
GoogleのColaboratoryを使って、PLATEAUのデータを全部処理して、独自のグリッドで区切った3Dタイルデータを作成します。
今日の分はダウンロードしてZipファイルからCityGMLの建物のファイルだけを展開する処理を説明します。

# Colaboratoryについて

https://colab.research.google.com/?hl=ja

これです。詳細と使い方はググってください。
以下、Colaboratoryの使い方や注意事項を分かっている前提で進めます。
折角処理したデータが1日経ったら消えた、どうしてくれるんだ、とか言われても困りますので、自己責任でお願いします。

# PLATEAUデータのダウンロード

はい、力技です。以下をセルに貼り付けて実行すると現行PLATEAUのデータがダウンロードできると思います。
東京が重複があったり、足りないもの多いものがあるかもしれません。必要があれば、[G空間情報センター](https://front.geospatial.jp)で確認してください。

ただ、残念なお知らせですが、これを実行するとColaboratoryで割り当てられたディスク容量を軽くオーバーしてしまいます。
