[Inkscape-user] NEWBIE: drawing maps ?

Please,

I am considering the use of Inkscape to draw simple maps. The main problem I see so far is the indication of roads. To do this I need to draw sets of two parallel curves a small distance apart. For rivers I need the same feature, but I need to colour the region between the lines.

I also need to create my own objects that I can place anywhere on the map: bridges, canal locks, compass points etc. But I get the impression this is quite easy.

How can I go about this ?

Thanks
