I have dataset of railways from OpenStreetMap. It is really detailed. But i want to make generalization for map scale 1:500 000: remove small details of the railways and short branches. I`ve used Collapse Dual Lines To Centerline, Collapse Road Detail, Merge Divided Roads, Thin Road Network tools For generalization of roads.

What is the best way for generalization of railway lines?


i removed the railways that were marked in OSM as abandoned, or tram, or sidding, or crossover lines etc. But there are too many lines without additional tags to filter.

example, Odessa railways before and after my manipulations.

    A simple Google search throws up these. – Hornbydd Sep 8 at 22:31
  • Which technique that you tried gave you your best result? What was that technique in detail? If its results did not meet your requirements then in what way did it fail? – PolyGeo Sep 8 at 22:46
  • @Hornbydd, thank you! most search results look like theory (research papers, generalization presentations, etc.), without detailing how to achieve the results they are talking about. As an example, here's the Merge Divided tool and its results. I'm a beginner at Arcgis and I want to have more practitioner tips. – Jonny Sep 11 at 12:56

    Try Integrate, but backup your data first – BERA Sep 11 at 15:32

    For a similar problem in QGIS, see gis.stackexchange.com/questions/319412/… Creating a dissolved buffer around railway tracks could be a start to resolve the problem, in ArcGIS as well as QGIS. – babel Sep 12 at 12:09
