Combine a number of geo graphics primitives in one map:

GeoGraphics supports 2D and 3D graphics primitives:

Large-scale maps use the equirectangular projection by default:

Intermediate-scale maps use the Lambert azimuthal projection centered at the geo range of the map:

Small scales are represented by default using the Mercator projection, to preserve angles:

Choose a projection with default parameters from GeoProjectionData[]:

Specify the parameters of a cylindrical projection using the default center meridian at Greenwich:

Choose any other meridian as the origin for projected longitudes:

Center the map at that longitude:

For cylindrical projections, easting represents longitude and is returned in degrees. Use radians instead:

Use a scale in kilometers for equatorial distance. The same radius geo disks show distance distortion:

Specify the parameters of an azimuthal projection, mainly the tangency point of the projection plane:

Some azimuthal projections cannot cover the whole world in a single map; the Lambert azimuthal projection can:

Specify the parameters of a conic projection by choosing a centering point:

Choose the standard parallels, which are true to scale, and draw them:

Geo primitives are defined in terms of {lat,lon} positions on the Earth and they are projected:

Standard primitives are defined in terms of map coordinates and they are not projected:

Standard primitives may be placed using GeoPosition[{lat,lon}], which is automatically projected:

A GeoPath (geodesic or loxodrome) is generically curved in the map:

The standard Line primitive is always a straight line in the map:

Coordinates coincide (though reversed) only for the equirectangular projection; use GeoPosition otherwise:

A filled GeoPath has generically curved sides in the map:

The standard Polygon primitive always has straight sides:

Compare both together:

Coordinate ranges for the map are determined by the total bounding box of all coordinates:

Coordinate specifications outside primitives contribute to the bounding box, but are not plotted:

Therefore this produces a map around a given geographical entity, with default geo range padding:

Coordinates in Graphics primitives that are not wrapped in GeoPosition are considered to be already in final projection. They also count toward the total coordinates range:

Use the default background for map region and background:
