Make sure the Load in QGIS when done option is checked. CLick OK. Back in the Georeferencer window, go to File ‣ Start georeferencing. This will start the process of warping the image using the GCPs and creating the target raster. Once the process finishes, you will see the georeferenced layer loaded in QGIS. The georeferencing is now complete.

What is linear referencing? Linear referencing is the method of storing geographic locations by using relative positions along a measured linear feature. Distance measures are used to locate events along the line: Locating a point event and a line event by measures along a line Measurements along features are used to locate point events and line events using a number of conventions.

Linear referencing is also used to associate multiple sets of attributes to portions of linear features without requiring that underlying lines be segmented (split) each time that attribute values change. For example, most road centerline feature classes are segmented where three or more road segments intersect and where the road names change. Registo de alterações do QGIS 2.18¶.

I had my eye on a solution involving linear referencing from the start and tried a couple of approaches before settling on the one I describe in detail below. I did find solutions using v.segment from GRASS and the QGIS LRS plugin but I felt these were too complex for a non-GIS specialist and they also involve several steps.

While it isn't as "slick" as the Esri world, the PostGIS world is far more featureful and flexible in my experience. Things like address geocoding and fuzzy matching exist and are perfectly usable in QGIS, topology networks and the like can be implemented, linear referencing has been a PostGIS function for years - versioning is probably the one big miss but you can roll your own.
