Gall Isographic vs. Equirectangular (35.6°)
Gall Isographic | Equirectangular (35.6°) | |
---|---|---|
Creator | James Gall (1855) | Marinus of Tyre (about AD 100) |
Group | Cylindric | Cylindric |
Property | Equidistant | Equidistant |

Remarks | Gall Isographic is the equirectangular projection with standard parallels at 45° North/South. | Here: Standard parallels at 35.6° (= 35° 36′) North/South. Values around these standard parallels nicely fill the space of a ISO-219 series A (A3, A4 etc.) paper sheet while at the same time leaving enough space for a legend above or below the map. |
