For example, I can run the Wizard query in Overpass Turbo: "highway=motorway AND oneway=yes in Chugoku" which gives me all the dual-carriage ways in the Chugoku region of Japan. Is there a way that I can calculate the total length of all these paths? I tried exporting to a KML and running some script but then I realized that the KML file was a folder that contained thousands of individual paths. I imagine there has to be a better way of doing this. |
Export to a format QGIS can handle. Then use a function of that program to calculate. Here's a tutorial |
