Import of the full dataset:

Import the full set of graphics primitives and represent them using GeoGraphics:

This is equivalent to using an explicit "Graphics" element:

Import a list of different geo primitives, in this case points, lines, multilines and polygons:

Import the list of layers:

Import the geometric type of each layer:

Import a map of the Royal Palace of Madrid, displaying its projected coordinate axes:

The "SpatialRange" element reports the projected ranges in the form {{x_min,y_min},{x_max,y_max}}:

Name of the cartographic coordinate system used by this GML file:

Name of the datum used by this GML file:

Length of the semimajor axis of the datum's reference ellipsoid:

Length of the semiminor axis of the datum's reference ellipsoid:

Inverse flattening of the datum's reference ellipsoid:

Units of the cartographic coordinates:

Name and parameters of the cartographic projection:

This projection coincides with the ellipsoidal "UTMZone30" projection:

Centering of the cartographic projection:

Standard parallels of the cartographic projection, with None denoting no standard parallels:

Central scale factor of the cartographic projection:

Grid origin of the cartographic projection in the same units of the reference model, in this case, meters:

Name of the cartographic projection:

Reference model of the cartographic projection:
