Basically we need this to define some sort of "protected area" (for
example, 30 cm in both sides from the cable) along some
telecommunication network cables (mainly optical) and therefore I don't
think only the representation would be sufficient. Probably some plugin
that would create polygon with a centralized line that we are "snapping
to" and with defined area (width) would be even better than just two
lines, because this way we could define some color of fill of that
closed "part" around cable in our projects for example. Hopefully I
explained it enough clearly, if you need more information, please let me
know :-)
Hello!
That sounds like you need a buffer :-)
In QGIS, you find this functionality under Vector (fTools plugin) ->
Geoprocessing (or similar, I have just the german version at hand at the
moment...)
