From :cite:`IOGP2018`:
The capital cites of each department in Colombia use an urban projection for large
scale topographic mapping of the urban areas. It is based on a plane through
the origin at an average height for the area, eliminating the need for corrections
to engineering survey observations.
proj-string: ``+proj=col_urban``
