A world map is shown by default in the equirectangular projection:

Use the Albers projection with default parameters:

Use the Albers projection with custom parameters and draw the standard parallels:

Maps of Canada in different projections, all with a 10-degree graticule:

The near side of the Moon:

Perform projections with default or automatic parameters:

Find out which parameters were used for the projection:

Specify your own projection parameters:

Project geo primitives with different projections:

In the equirectangular projection, the disk center is in the middle of the end points of the geodesic path:

In the Lambert azimuthal projection, the geodesic looks almost straight and the geo disk circular:

When no explicit projection is requested, one is automatically chosen:

When one or more non-geo graphic primitives appear and no projection is explicitly requested, the equirectangular projection is always used:

Use GeoDisk, Line[{GeoPosition[…], …}], etc. to place correctly projected primitives on the map:

Alternatively, specify a projection explicitly to combine primitives with regular graphics on the same coordinate scale as projected geo graphics:

Study geo projection distortion of the graticules, the grid of lines of constant latitude and longitude:

Use the gnomonic projection to map the surface of the Earth onto the faces of a polyhedron:

Project onto a dodecahedron:

Project onto an icosahedron:
