<br>
With other contributors in Connecticut, we would like to import<br>
building footprints. We have evaluated different data sources, and<br>
concluded that no Connecticut-wide sources were usable without a lot of<br>
manual work to fix building geometry.<br>
<br>
We found that the WestCOG has very accurate building footprint data on<br>
its territory (south west Connecticut), available online and with a<br>
compatible license (CC0):<br>
<a href="http://data.westcog.org:8080/GIS_data/Buildings.gdb.zip" rel="noreferrer noreferrer" target="_blank">http://data.westcog.org:8080/GIS_data/Buildings.gdb.zip</a><br>
That's 513,141 buildings, and 296,423 building parts in some of them,<br>
that cover this territory:<br>
<a href="https://westcog.org/wp-content/uploads/2015/08/WestCOG_Locus_Map-e1439920850177-790x1024.jpg" rel="noreferrer noreferrer" target="_blank">https://westcog.org/wp-content/uploads/2015/08/WestCOG_Locus_Map-e1439920850177-790x1024.jpg</a><br>
<br>
Other COGs unfortunately don't share this data online. We hope that a<br>
successful import could be a convincing argument for other COGs to open<br>
their data.<br>
<br>
We have documented our current plan at<br>
<a href="https://wiki.openstreetmap.org/wiki/Connecticut/Western_COG_Building_Import" rel="noreferrer noreferrer" target="_blank">https://wiki.openstreetmap.org/wiki/Connecticut/Western_COG_Building_Import</a><br>
on the wiki.<br>
<br>
We have contacted local mappers of this part of<br>
Connecticut (we are based in and around New Haven, not is south-west<br>
Connecticut), with no negative feedback and 2-3 positive responses. We<br>
have created a process to convert the data from WestCOG to OSM tags and<br>
files that can easily be loaded in JOSM.<br>
<br>
We have never done an import before, so we'd appreciate any advice on<br>
how to properly do the import. From our reading the wiki, we should use<br>
a separate user to import the data. Is that one shared user for the<br>
import, or one user for each person importing data?<br>
<br>
We have identified potential issues with this import: roads and<br>
waterways come from an old import and might very well cross the<br>
buildings we'd like to import. For now, we have a task on the osmus<br>
task manager to try and correct road geometry (currently finished at<br>
50%) that covers Fairfield County (WestCOG is a part of Fairfield<br>
county): <a href="https://tasks.openstreetmap.us/project/193" rel="noreferrer noreferrer" target="_blank">https://tasks.openstreetmap.us/project/193</a>. This is not going<br>
very fast, so we'd like to start the import even though we haven't<br>
finished the tasks. We plan to fix road and water issues as we<br>
encounter them instead, while encouraging people to go and fix them<br>
independently from our import.<br>
<br>
WestCOG currently has almost no building mapped, but obviously we plan<br>
to keep existing buildings and only import buildings that are not yet<br>
mapped.<br>
<br>
What is a good way to split this import? Is there a good size per<br>
changeset that you could recommend?<br>
<br>
Thanks for your help!<br>
<br>
Julien<br>
