I have extracted a small area of Welwyn Garden City using osmosis bounding box. When I analyse the data using my program, (or JOSM) it reports some nodes are missing, about 11,000 out of 250,000. This may/will be over-estimated due to several ways sharing nodes. Are these nodes outside the bounding box? Is this 'ok'. Is it something you have to 'cope with'.

One Answer:
You should likely be setting "completeWays" https://wiki.openstreetmap.org/wiki/Osmosis/Detailed_Usage_0.47#Area_Filtering_Tasks when extracting, and perhaps even the equivalent setting for relations. While editing apps can in general handle referentially incomplete relation data, doing the same with ways, resp. way nodes is not a good idea (maybe JOSM does something reasonable, but I wouldn't count on it).. answered 14 Jun '19, 07:04  SimonPoole ♦ |
