Projection type

The Maps control supports the following projection types:

  • Mercator
  • Equirectangular
  • Miller
  • Eckert3
  • Eckert5
  • Eckert6
  • Winkel3
  • AitOff

By default, the Maps are rendered by the Mercator projection type in which the Maps are rendered based on the coordinates. So, the Maps is not stretched. To change the type of projection in the Maps, the projectionType property is used.
