<p style="margin-top:0;margin-bottom:0">Hi,</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">Looking towards overhauling the import system I use for my Freemap site (free-map.org.uk) which is itself going to go through an overhaul in the near future by moving to Tangram and hopefully applying hill shading.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">At the moment I download full planet extracts about every 6 months. However, due to the limitations of my server, I filter out (with osmosis) a lot of stuff I don't need so that I am basically left with roads, footpaths,
natural features, water features and selected POIs.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">I'd like to move towards a system which applies diffs from geofabrik instead, and applies them regularly (daily or weekly) with osm2pgsql.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">My question is this; given that not everything in the diff will be in my database (as I filter out what I don't need during the import process), will osm2pgsql apply the diff successfully or will it complain that not
all features in the diff are in my database?</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">Thanks,</p>
