Can I suggest for the Twin Cities metro area someone doing something similar with the Metro Regional Centerlines Collaborative Local Centerlines (MRCC)? I know that Dakota County hasn’t submitted centerlines to Tiger in a couple of years, but will be for the next update. Not sure about the other counties though. There very well may be areas that the MRCC will be a better source than the Tiger data.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><a href="https://gisdata.mn.gov/dataset/us-mn-state-metrogis-trans-mrcc-centerlines">https://gisdata.mn.gov/dataset/us-mn-state-metrogis-trans-mrcc-centerlines</a></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Joe</p><p class=MsoNormal><o:p> </o:p></p><div style='mso-element:para-border-div;border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal style='border:none;padding:0in'><b>From: </b><a href="mailto:ian.dees@gmail.com">Ian Dees</a><br><b>Sent: </b>Wednesday, October 11, 2017 10:25 AM<br><b>To: </b><a href="mailto:baditaflorin@gmail.com">Badita Florin</a><br><b>Cc: </b><a href="mailto:talk-us@openstreetmap.org">talk-us@openstreetmap.org Openstreetmap</a><br><b>Subject: </b>Re: [Talk-us] Comparing Tiger 2017 dataset with OSM in a automatedway.</p></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>It would be interesting to see what differences CYGNUS would turn up.

Then I downloaded an osm-qa-tiles (<a href="https://osmlab.github.io/osm-qa-tiles/">https://osmlab.github.io/osm-qa-tiles/</a>) file for the United States and ran osmlint's tigerDelta (<a href="https://github.com/osmlab/osmlint/tree/master/validators/tigerDelta">https://github.com/osmlab/osmlint/tree/master/validators/tigerDelta</a>) to find the segments that had different geometry. The output was then ran through Tippecanoe to generate a vector tileset and posted to Mapbox as the low zoom red features.</p></div></div><div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>On Wed, Oct 11, 2017 at 4:03 AM, Badita Florin <<a href="mailto:baditaflorin@gmail.com" target="_blank">baditaflorin@gmail.com</a>> wrote:</p><blockquote style='border:none;border-left:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;margin-left:4.8pt;margin-right:0in'><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=RO>Hi, i wanted to ask if there will be interest around comparing TIGER 2017 with what we have in OSM, using CYGNUS, in a automated way. <a href="http://www.openstreetmap.org/user/mvexel/diary/36746" target="_blank">http://www.openstreetmap.org/user/mvexel/diary/36746</a></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=RO> </span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=RO>On top of cygnus, i have developed shgp2cygnus, were you can place any shapefile, any size, you provide a translation file, and, in the end, you get a list with all the ways that are in the TIGER dataset, but not in OSM.</span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=RO>This would be something useful for the community ? </span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=RO> </span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=RO>I don`t know if somebody is already doing something similar, or what is the status ?
