Equidistant conic projection

The equidistant conic projection was described by the Greek philosopher Claudius Ptolemy about A.D. 150. It is neither conformal or equal-area, but serves as a compromise between them. The scale is true along all meridians and the standard parallels.

dlon0/lat0/lat1/lat2/scale or Dlon0/lat0/lat1/lat2/width

• d or D: Sets the projection type.

• lon0/lat0: Sets the projection center.

• lat1/lat2: Sets the two standard parallels.

• scale or width: Sets the map size.
