I want to project data of China. I'm not concerned with trying to preserve areal or directional relationships but preserving distances would be nice.

Does such a coordinate system exist?


I would recommend an Azimuthal Equidistant projection for what you are looking for. This type of projection:

"preserves true scale from a single specified point on the projection to all other points on the map."

The example below I set the central meridian to be near Beijeng, China for perspective.

enter image description here

Here are additional resources:

Choosing a projection

Azimuthal equidistant projection, centered on Beijing, China, 39⁰55ʹN, 116⁰23ʹE.

  • Thanks! Can you detail on what "equidistant" means in the context of projections? What has the same/equal distance to what? – Julian Jun 29 '17 at 6:31
  • I would recommend post a new question so that the GIS community may benefit in viewing the post and all have a chance to provide a response. I'll keep a look out for it, or if you may respond here that it is up I can try to provide the best response I can. Hope that helps. – whyzar Jun 29 '17 at 18:13
