膨大な位置情報の距離を計算するような場合に、対象の都道府県と隣接する都道府県に限定して距離計算を行うことで計算量を削減するためのAppleScriptです。
対象は日本国内の都道府県。海外の住所情報でも同様に都道府県にコードを振って隣接情報をデータ化すれば同様の処理は可能です。
| AppleScript名：都道府県リストから隣接都道府県を含む該当のコードを抽出する |

iMac Proを試してみた – AppleScriptの穴 says:
[…] もともと90分かかっていたところを隣接都道府県テーブルの導入により10分へ短縮、そしてデータの形式を見直すことで５分程度に処理短縮していたものですが、実験したバージョンでは […]
