@TeddyTedTed's answer is nice, however, I am looking for something more efficient.
I am working on a public transport network in one shapefile (polyline type) in QGIS 2.18.
Certain bus routes share the same paths, means that one line-part can repeat more than once. It always has the same identical geometry.
For instance, if I select a feature with
'Identify Features' I will have three outcomes in the Identify results table, see an image below.
I want to select all the features that share the same geometry and further process it with no deletion. I intend to sign an attribute that says if the layer overlaps.
Can you suggest the most beneficial way? Maybe a Virtual Layer?
So far I have in mind:
Vector > Research Tools > Select by location. However, I am not that certain regarding the
geometric predicate. Because the
'overlaps'do not give me any sufficient outcome.
Vector > Geometry Tools > geometry checker, do not know what to choose in conditions and properties.
Plugins > Geometry Validator > Validate geometries, does not provide any errors notifications.
