1. MAP PROJECTION

2. A way to represent the curved surface of the earth on the flat surface of a map Map projection depends on the scale of the map, purpose Map projection varies with the size and location of different areas on the earth’s surface Transferring globe-on a plane surface –preservation of area, shape, bearing(direction and distance) MAP PROJECTION

4. Equal area or homographical projections Correct shape or orthomorphic projections True bearing or azimuthal projections Groups of projections according to the quality they preserve

5. 1.Perspective 2. Non-perspective Based on the developable surface used 1.Conical 2.Cylindrical 3.Azimuthal or zenithal 4.Conventional Based on the method of constructions

7. Homolographic or equal area Orthomorphic Azimuthal or true bearing projections Based on the position of tangent surfaces 1.Polar 2.Equatorial or normal 3.Oblique Based on the preserved qualities

8. Polar projection

10. Gnomonic Stereographic Orthographic Based on Geometric shape 1. Rectangular 2. Circular 3. Elliptical 4. Butterfly shape Based on the position of view or light

11. Elliptical Rectangular Butterfly shape

12. Zenital projection Conical projection Cylindrical projection Map scales
