- The changeset source tag, shouldn't that be something like - City of<br>
Chicago, data set "blablabla". The github link will probably be dead<br>
in 5 years. You could use a website= tag on the change set for the<br>
github repo link.<br></blockquote><div><br></div><div style>source=* has always meant (to me at least) the actual URL or place you obtained the data from -- similar to a citation in Wikipedia. I can add a description mentioning the city of chicago datasets though.</div>
<div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">- The wiki says that you are planning on manually checking for<br>
overlaps with the existing buildings. If you have already done half of<br>
the city, then you are still going to need to check over 500,000<br>
buildings by hand. It seems like a lot! I am much to lazy for that. My<br>
code for MA is below, it does a check for existing building and looks<br>
for schools and airports that are not tagged correctly.<br>
