latlon_to_local — DRIVE `japan` op

• Data kinds: any × any → any

• Call: import fullseye as fs; fs.ledger.latlon_to_local(lat, lon, origin) -> 'Tuple[np.ndarray, np.ndarray]' (to call the implementation directly, import drivejapan; drivejapan.latlon_to_local(lat, lon, origin) -> 'Tuple[np.ndarray, np.ndarray]'; from the registry, opsdrive.get("latlon_to_local"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

緯度経度 [deg] → 原点 origin = (lat0, lon0) まわりの等距円筒近似の平面座標 (x 東, y 北) [m]。

x = R cos(lat0) Δλ、y = R Δφ(R = 6378137 m)。1 km 四方で 1e-5 の歪み(cos の変化)なので町 1 つには十分。配列可。

Raises `ValueError`: 緯度経度が範囲外・非有限。
