<br>
this is just a small heads-up. The Geofabrik downloads (regional<br>
.osm.pbf extracts for various continents, countries etc) will switch to<br>
a different software stack later this month. We currently use<br>
osm-history-splitter which is based on an older version of Osmium, and<br>
will in the future use a new feature offered by the osmium command line<br>
tool and the newest Osmium version instead.<br>
<br>
This will enable us to change the handling of relations in the extracts.<br>
<br>
Currently, relations are included in the extracts if one of their<br>
members lies (partially) inside the area; but members of the relation<br>
that lie fully outside the area are not considered.<br>
<br>
This has adverse effects when large multipolygons cross the border, for<br>
example Lake Constance not be fully contained in any of the Germany,<br>
Austria, or Switzerland extracts.<br>
<br>
In the future we will be able to include all members of multipolygon<br>
relations that have at least one member (partially) inside the area.<br>
This will only be done for multipolygons and not for other relations<br>
(like boundaries or routes). Therefore, water bodies, forests etc. that<br>
cross the boundary should in the future be fully contained in the extracts.<br>
<br>
This comes at a price of a slightly larger extract but the difference is<br>
negligible. On the day we make the switch, all regional .osc files will<br>
have a slight size bump becasue all the missing bits and pieces required<br>
to complete the multipolygons will be contained in them.<br>
<br>
Bye<br>
