GeoJSON をベクトルタイル化

今回はnameプロパティだけ抽出
zoomレベルは-z22 -Z10
レイヤーネームは"tokyo-to_evacuation"

作成したGeoJSONファイルがある階層でコマンド実行

tippecanoe --no-tile-compression -z22 -Z10 -e tokyo-to_evacuation -y name -l okyo-to_evacuation -ai tokyo-to_evacuation.geojson

無事成功。完成物はここに格納

注意点

コピペみすして、レイヤーネームが"okyo-to_evacuation"になっていた。
あとで修正します。
