I have a South America import and an osm2po topology table. My database is updated daily using osmosis but how to keep the topology table updated without make all import over again?


even small changes force a complete rebuild of the osm2po topology. The reason are the OSM-IDs which change with each new delta.

  • Of course, only when sth. changes. But then everything can happen. Imagine someone adds a new node C between A and B. Then deletes B and moves C to Bs position. And there are more examples. – Carsten Apr 23 '17 at 18:43
  • Makes sense. This is bad! Rebuild all topology at every planet update is impossible. What can I do? – Magno C Apr 24 '17 at 11:34
