I'm currently creating a worldmap. For technical reasons, I want to do it on a computer, as a vectorial image (I can't use pixel images because I need small details).
For more accuracy, I want to have a mastermap with equirectangular projection, and then convert some small areas of it to stereographic projection to be able to work on them with minimal distortion. When I'm finished with an area, I'll convert it back to equirectangular projection, to "stick" it on the mastermap.
However, I haven't found any way to convert vectorial maps (they are svg files) from equirectangular projection to stereographic projection, and vice-versa. I found some projection converters for pixel images, but they don't work with vectorial images.
So, does anyone know any software or any way to convert vectorial maps to different projections? Thanks.
Post-scriptum: I mainly use Inkscape.
