- More descriptive, and used by Esri
- Spheroid projections: WGS84, WGS72
The two definitions for a spheroid -
correct answer ✅1. An ellipsoid that approximates the shape of a
sphere (Used by this course)
2. An ellipsoid created by rotating an ellipse about either its major
axis (prolate ellipsoid) or its minor axis (oblate ellipsoid)
