- wradlib.georef.projection.get_earth_radius(latitude, sr=None)[source]#
Get the radius of the Earth (in km) for a given Spheroid model (sr) at a given position.
\[R^2 = \frac{a^4 \cos(f)^2 + b^4 \sin(f)^2} {a^2 \cos(f)^2 + b^2 \sin(f)^2}\]- Parameters:
sr (
osgeo.osr.SpatialReference) – spatial referencelatitude (
float) – geodetic latitude in degrees
- Returns:
radius (
float) – earth radius in meter
