General:

• Debian
• CLI tool "OSM-PostgreSQL-Experiments" (ope): https://github.com/osmcode/osm-postgresql-experiments , z.B. src/ope -H 000.osc.gz obj=o%o.I.v.d.c.t.i.T.x.y.N.M.
• CLI tool ourtool zum Ausschneiden mittels Python (License GPL3 - like )

Notes:

• Boundary CH: https://planet.osm.ch/switzerland-exact.poly
• osm-history-renderer (unmaintained): https://github.com/MaZderMind/osm-history-renderer

Tool Chain:

• Initialize: src/ope -H liechtenstein.osh ...
• Find initial minutely seq. no. nnn. manually with timestamp (or automagically using pyosmium)
• Repeat
  • Download minutely change file using wget (or pyosmium getchange ...)
  • Create nnn.pgsql using src/ope -H nnn.osc.gz node=n%I.v.d.c.t.i.T.x.y way=w%I.v.d.c.t.i.T.N. rels=r%I.v.d.c.t.i.T.M.
  • psql < node.pgsql ; psql < ways.pgsql ; psql < relspgsql
  • ourtool.py mydb -- remove outside boundary 1. node by location, 2. way by missing node_id, 3. rels by missing nwr members.
• tbc.
