Hello:) I need to do map with Braun´s stereohraphic cylindrical projection, but arcgis can make only Gall´s projection. Is there any way how can I change it to Braun´s? Thank you for your ideas.
No, unfortunately, we don't have it. In a sense, it's the generic case of Gall's stereographic, but unlike Gall's which has standard parallels at +/-45, the standard parallel is the equator.
Melita Kennedy mlght know
perhaps it is not implemented an I don't think it a simple matter of changing the scaling without recalculating the coordinates. I am sure you have seen already but for others ... Gall stereographic projection
