Summary
| Description |
English: The Craig Retroazimuthal (aka "Mecca") projection. Centred on Makkah, you can measure the great-circle azimuth to Makkah from any other point on the map by measuring the angle from the vertical. Like all retroazimuthal projections, distortion is high near the edges, and there are unusual "wrap around" effects, seen here as an overlap in the reticle at the bottom of the map.
The template is a Visible Earth image collected by the Earth Observatory experiment of the U.S. Government's NASA space agency. The reticle is 15 degrees in latitude and longitude. |
