I agree. I will make a third osm file that just has overlapping buildings, it is very easy. Then, put them away for after the dust settles on the missing buildings.<br><div><br></div><div><div class="gmail_quote">On Thu, Dec 13, 2012 at 8:45 PM, Greg Troxel <span dir="ltr"><<a href="mailto:gdt@ir.bbn.com" target="_blank">gdt@ir.bbn.com</a>></span> wrote:<br>

</div></div>That makes sense. I am afraid that I think this process should be<br>
manual.<br>
<br>
>From the scripts, it would be nice to produce a partition of the massgis<br>
data as:<br>
<br>
buildings_not_in_osm<br>
buildings_overlapping_buildings_in_osm<br>
<br>
the second can be used for 'replace geometry' or the conflation plugin,<br>
with manual imagery checking (or at the discretion of the one who added<br>
them).<br>
<br>
Later, as things change, one could rerun the massgis data (or an update)<br>
and produce<br>
<br>
buildings_matching_osm (to be ignored)<br>
buildings_not_in_osm<br>
buildings_overlapping_buildings_in_osm<br>
<br>
and the 3rd set is again where we haven't updated or think our data is<br>
better. I would say this whole process can wait until the dust settles<br>
on the import of non-overlapping data.<br>
