# Colombia Urban¶

New in version 7.2.

 Classification Miscellaneous Available forms Forward and inverse ellipsoidal projection Alias col_urban Domain 2D Input type Geodetic coordinates Output type Projected coordinates

From [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.
