bqplot.scales.Stereographic

class bqplot.scales.Stereographic(**kwargs)

A perspective projection that uses a bijective and smooth map at every point except the projection point.

The projection is not an equal-area projection but it is conformal.

scale_factor

Specifies the scale value for the projection

Type:float (default: 250)

rotate

Degree of rotation in each axis.

Type:tuple (default: (96, 0))

center

Specifies the longitude and latitude where the map is centered.

Type:tuple (default: (0, 60))

precision

Specifies the threshold for the projections adaptive resampling to the specified value in pixels.

Type:float (default: 0.1)

clip_angle

Specifies the clipping circle radius to the specified angle in degrees.

Type:float (default: 90.)
