I'm not sure exactly where in the map rendering process the detail being discussed here lies, but it would be my preference to resolve nodes down to 1m. There are plenty of instances where complex junctions have many roads, footpaths, gates, bollards, cattle grids and stiles all within a 10m radius, on both sides of a country road, expanding the resolution to 25m would make a mess of carefully plotted features and make it even more difficult to render at the highest zoom. If the rendering produces a cluttered map, then that's a rendering issue, but for routing, complex junctions need fine resolution. WessexMario
