 A Rust, Python and JavaScript (WASM) library for calculating geoid heights for Japan using [GSI's geoid model](https://fgd.gsi.go.jp/download/geoid.php). This library contains geoid data based on `gsigeo2011_ver2_2.asc`, created with permission: 「測量法に基づく国土地理院長承認（使用）R 5JHs 560」.
 
-Rust および Python で日本のジオイド高を計算するためライブラリです。国土地理院のジオイドモデル「[日本のジオイド2011](https://fgd.gsi.go.jp/download/geoid.php)」を用いて、国土地理院による C++ のサンプルコードに準拠した補間計算を行います。本ライブラリは、日本のジオイド2011 v.2.2 (`gsigeo2011_ver2_2.asc`) を元にしたジオイドデータを含んでいます（測量法に基づく国土地理院長承認（使用）R 5JHs 560）。
