I live in Kananga, DR Congo. I have made a fairly detailed and accurate map of the city in SVG. Is there a way that I can convert the SVG file into GPX traces that I could then use to greatly expand the existing map on OSM. Software I currently use is QGIS, Merkaartor, Inkscape and am downloading JOSM as I write. Thanks
Hmm, let’s listen to the wiki:
http://wiki.openstreetmap.org/wiki/SVG tells you only how to get an SVG file from OSM data, but not vice versa.
http://wiki.openstreetmap.org/wiki/Converting_map_data_between_formats says that it is not possible to convert SVG into OSM directly.
Maybe the best approach is to find a way to convert your SVG data in http://wiki.openstreetmap.org/wiki/Shapefiles and then into OSM data …
An option would be to export the SVG to PNG (through Inkscape) and open it as a background in JOSM using the PicLayer plugin. You can then draw OSM objects on top of that.
