NEED TO KNOW NOW!!!

Truly a difficult homework assignment Sabrina. I didn't know there were four major flat-map projections.

Three of them look down right strange.

There are general or thematic,
Planimetric, topographical or charts.
Examples of maps - world, political, physical, vegetation, religious, economic, road, weather, relief, star, orthophoto, aeronautical, nautical and satellite maps and atlases and/or GPS cooridinates.

You left out Mercator . . .

I believe the only geometric possibilities are projections (1) on a plane or (2) on a cylinder.

Projection on a tangent plane is called a gnomic projections. The most common are tangent at a pole.

Projection on a cylinder tangent at the equator is caled a Mercator projection - the one Setanta noted.

One occasionally encounters projections on the equatorial plane, but I don't know what they are called.
