Implementations

impl GeoLocation

pub fn to_wgs84(&self, transformer: &JgdTransformer) -> Option<(f64, f64)>

WGS84座標系に変換した座標を取得

国土地理院のTKY2JGD/PatchJGDパラメータを使用して Tokyo Datum/JGD2000 → JGD2011 → WGS84 の変換を行う。

Arguments

• transformer - JgdTransformer インスタンス

Returns

Some((経度, 緯度)) - WGS84座標系での10進数座標 None - 座標が取得できない場合

Example

let transformer = JgdTransformer::new("TKY2JGD.par", "patch_files")?;
let (lng, lat) = location.to_wgs84(&transformer)?;

pub fn to_decimal(&self) -> Option<(f64, f64)>

10進数座標を取得 (変換なし)

Returns

Some((経度, 緯度)) - 10進数座標 None - 座標が取得できない場合

pub fn datum(&self) -> GeodeticDatum

測地系を取得

Trait Implementations

impl Clone for GeoLocation

fn clone(&self) -> GeoLocation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GeoLocation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for GeoLocation

fn eq(&self, other: &GeoLocation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
