Three Basic Categories of map projections are:

• Planar Projection• Cylindrical Projection• Conic Projection

Planar surface Earth intersectsthe plane on a smallcircle. All points on circle have no scale distortion.

Conic surface Earth intersects thecone at two circles.all points along bothcircles have no scaledistortion.

Winkel Tripel Projection • Presented by Oswald

Winkel in 1921

• Most general reference maps are the Winkel Tripel Projection.

• The map provides goood balance between the size and shape of land areas. Even the polar areas are depicted with little distortion of size and shape.
