Someone on wikimedia commons has requested a redraw of a map. It is now a png-file and it must become a svg-file.
This is what I have done: I have downloaded the file and then imported it in Inkscape. I embedded it and then used Trace Bitmap. That worked but it also erased all the color from the picture. This is the result:
Simply use the paint bucket ! That will be even more precise than tracing the picture with its colors. You may also import the original bitmap and copy each color with the Color picker before filling the corresponding surfaces with the paint bucket.
