Smart constructors

latLong :: Angle -> Angle -> LatLong

LatLong from given latitude and longitude. errors if given latitude is outisde [-90..90]° and/or given longitude is outisde [-180..180]°.

latLongE :: Angle -> Angle -> Either String LatLong

LatLong from given latitude and longitude. A Left indicates that the given latitude is outisde [-90..90]° and/or given longitude is outisde [-180..180]°.

latLongF :: MonadFail m => Angle -> Angle -> m LatLong

LatLong from given latitude and longitude. fails if given latitude is outisde [-90..90]° and/or given longitude is outisde [-180..180]°.

latLongDecimal :: Double -> Double -> LatLong

LatLong from given latitude and longitude in decimal degrees. errors if given latitude is outisde [-90..90]° and/or given longitude is outisde [-180..180]°.

latLongDecimalE :: Double -> Double -> Either String LatLong

LatLong from given latitude and longitude in decimal degrees. A Left indicates that the given latitude is outisde [-90..90]° and/or given longitude is outisde [-180..180]°.

latLongDecimalF :: MonadFail m => Double -> Double -> m LatLong

LatLong from given latitude and longitude in decimal degrees. fails if given latitude is outisde [-90..90]° and/or given longitude is outisde [-180..180]°.

read

readLatLong :: String -> LatLong

Obtains a LatLong from the given string formatted as either:

• DD(MM)(SS)[N|S]DDD(MM)(SS)[E|W] - e.g. 553621N0130002E or 0116S03649E or 47N122W
• Angle[N|S] Angle[E|W] - e.g. 55°36'21''N 13°0'02''E or 11°16'S 36°49'E or 47°N 122°W

This simply calls read s :: GeoPos so error should be handled at the call site.

readLatLongE :: String -> Either String LatLong

Same as readLatLong but returns a Either.

readLatLongF :: MonadFail m => String -> m LatLong

Same as readLatLong but returns a MonadFail.

Misc.

toDecimalDegrees' :: LatLong -> (Double, Double)

Converts the given LatLong to tuple of latitude and longitude in decimal degrees.
