Orthographic
Name | Orthographic |
Model | Azimuthal |
Type | n/a |
Meridians | Polar: Straight lines radiating from point of tangency Oblique: Ellipses concave toward the center of the projection Equatorial: Ellipses concave toward the straight central meridian |
Parallels | Polar: Concentric circles Oblique: Ellipses concave toward the poles Equatorial: straight and parallel |
Spacing Meridian | Polar: Equal and increases Oblique: Decreases from the center of the projection Equatorial: Decreases from the center of the projection |
Spacing Parallels | Polar: Decreases from point of tangency Oblique: Decreases from the center of the projection Equatorial: Decreases from the center of the projection |
Linear Scale | Polar: True on parallels All: On all circles centered on pole Scale decreases along lines radiating from center of projection |
Specialties | Earth appears as it would from outer space Truly graphical representation of the earth Distortion becomes a visual aid Most familiar of the Azimuthal projections |
Uses | Earth from outer space |
