I have a polyline layer and an external csv containing road sign data. The csv has unique ID of the polyline, chainage along each unique segment and an offset. I have access to ArcGIS, MapInfo and QGIS, is there any way I can generate point data from this data?

Using Linear Referencing of ArcGIS for Desktop the steps are:

  1. Create Routes to create routes from your polylines
  2. Make Route Event Layer to place your road signs as point events along the routes
  3. Copy Features to copy point events to a point feature class
