Method Details

__init__ (self, datum=None, raiser=False, **name)
(Constructor)

 

New Be*LBG transformer instance, optionally with a different conic's datum.

Arguments:
  • datum - Conic's datum to use (pygeodesy.Datums, ellipsoidal only).
  • raiser - If True raise a BeLBGError for lat- or longitudes outside region4 or below bounds4 (bool).
  • name - Optional name name=NN (str).
Overrides: object.__init__

bounds4 (self, asLb=False)

 

Get the South, West, North and East bounds of this Lambert conic projection.

Arguments:
  • asLb - Use asLb=True for the bounds in local Lambert easting and northing, otherwise in geodetic lat- and longitudes (bool).
Returns:
A Bounds4Tuple(latS, lonW, latN, lonE) with (WGS84) geodetic lat- and longitudes in degrees or an Lb4Tuple(minE, minN, maxE, maxN) in meter.
Overrides: _BeLBGbase.bounds4

Note: The bounds4 cover Belgium, Belgium's EEZ, the Netherlands, the Netherlands' EEZ and Luxemburg.

forward (self, lat, lon, height=0, **raiser_name)

 

Convert geodetic (lat, lon) and (ellipsoidal) height to easting, northing and (orthometric) height H.

Arguments:
  • lat - Latitude (degrees, geodetic).
  • lon - Longitude (degrees, geodetic).
  • height - The (ellipsoidal) height (meter, conventionally) or None to ignore hBGh interpolation.
Returns:
A BeLBG7Tuple(easting, northing, H, lat, lon, height, beLBG) with easting, northing and (orthometric) height H in meter or NAN and beLBG is this Be*LBG instance.
Raises:
  • BeLBGError - If the point is outside the BG region and property raiser is True or keyword argument raiser=True.
Overrides: _BeLBGbase.forward
Notes:
  • H, easting and northing will all be NAN if lat or lon is below this converter's bounds4.
  • Orthometric height (H = h - N) euals ellipsoidal height h less (hybrid quasi-) geoid height N.

hBGh (self, lat, lon)

 

Interpolate the hybrid quasi-geoid hBG height for a geodetic point.

Arguments:
  • lat - Latitude (degrees, geodetic).
  • lon - Longitude (degrees, geodetic).
Returns:
Hybrid quasi-geoid hBG height N (meter) or NAN if lat or lon is outside region4.
Overrides: _BeLBGbase.hBGh

hBGh3 (self, easting, northing)

 

Interpolate the hybrid quasi-geoid hBG height for a local point.

Arguments:
  • easting - Easting (meter, local).
  • northing - Northing (meter, local).
Returns:
LatLonN3Tuple(lat, lon, N) with the (hybrid quasi-) geoid hBG height N in meter or NAN if lat or lon is outside region4.
Overrides: _BeLBGbase.hBGh3

isinside (self, lat, lon, eps=0)

 

Is geodetic (lat, lon) inside the hBG region?

Arguments:
  • lat - Latitude (degrees, geodetic).
  • lon - Longitude (degrees, geodetic).
  • eps - Over-/undersize the hBG region (degrees).
Returns:
None if lat or lon is NAN, False if outside the hBG region, True otherwise.
Overrides: _BeLBGbase.isinside

See Also: Methods Bounds4Tuple.isinside and Lb4Tuple.isinside.

region4 (self, asLb=False)

 

Get the South, West, North and East bounds of the hBG region.

Arguments:
  • asLb - Use asLb=True for the bounds in local Lambert easting and northing, otherwise in geodetic lat- and longitudes (bool).
Returns:
A Bounds4Tuple(latS, lonW, latN, lonE) with (WGS84) geodetic lat- and longitudes in degrees or an Lb4Tuple(minE, minN, maxE, maxN) in meter.
Overrides: _BeLBGbase.region4

Note: The hBG region covers all of Belgium, Luxemburg and the southern half of the Netherlands.

reverse (self, easting, northing, H=0, **raiser_name)

 

Convert local easting, northing and (orthometric) height H to geodetic lat-, longitude and (ellipsoidal) height.

Arguments:
  • easting - Easting (meter, local).
  • northing - Northing (meter, local).
  • H - The (orthometric) height (meter, conventionally) or None to ignore hBGh interpolation.
Returns:
A BeLBG7Tuple(easting, northing, H, lat, lon, height, beLBG) with geodetic lat and lon and (ellipsoidal) height in meter or NAN and beLBG is this Be*LBG instance.
Raises:
  • BeLBGError - If the point is outside the hBG region and property raiser is True or keyword argument raiser=True.
Overrides: _BeLBGbase.reverse
Notes:
  • All lon, lat and height will be NAN if easting or northing is below this converter's bounds4(asLb).
  • Ellipsoidal height (h = H + N) equals orthometric height H plus (hybrid quasi-) geoid height N.
