Is it possible to provide the sample data to understand the input data you have ? Mon,12 Oct 2015 04:53:48 GMT pratap Comment by dr_ysg https://knowledge.亚搏在线safe.com/comments/15454/view.html Probably QGIS will work,but we want 3-4cm accurracy of the road boundaries.The task I was given was to take an OSM map with low accurracy and improve it.It has ways for road boundaries and extra tags on the ways for center lines,and lane lines and boundaries.But my guess was doing this from scratch with the GPS data was better.Don't you agree?And yes,perhaps hand drawing with QGIS is the way to go,but can FME assist at all?

For such a small area,wouldn't it be quicker just to do it manually in e.g.ArcMap or QGIS?
