Stereographic
Name | Stereographic |
Model | Azimuthal |
Type | n/a |
Meridians | Polar: Straight lines radiating from point of tangency Oblique: Arcs of circles concave toward straight central meridian Equatorial: Arcs of circles concave toward straight central meridian |
Parallels | Polar: Concentric circles Oblique: Non-conic arcs of circles concave towards one of the poles Equatorial: Non-conic arcs of circles concave towards the poles |
Spacing Meridian | Increases away from the center |
Spacing Parallels | Increases away from the center |
Linear Scale | Increases toward the edges |
Specialties | Directions from the center are true Generally only one hemisphere is displayed |
Uses | Spherical geometry physics Most widely used of the Azimuthal projections Polar maps |
