Stretch, Haymarket relation broken. Looks like it's at the north 9th street top.

J, thx for staying on top of the notes, adding the building, and for cleaning up the alignment!

I think the railway=tram was accidently changed to a manmade=pipeline. As for the crossing, I think should either be surface asphalt, or cut it into three sections, two asphalt and one concrete . Also, the intersection of the crossing with the tram should be a node, railway=tram_level_crossing

Sansom and 4th crossing has a surface of concrete? but 4th has a surface of asphalt.

alternative see osm.wiki/Key:disused:*

The outline for the college seems to need updating. Looks like it includes a garage/mechanic next door. Also, some buildings may be vacant. thx.

Hi smikhnouski. Kensington Circle seems to be named Cout on philly public data, so I changed it. Can you verify with your Lyft sources? Thanks. here's the philly link: https://atlas.phila.gov/2142%20KENSINGTON%20CT/condos

Hi Mark, new? You seem to be doing great! Keep up the surveying and mapping. If you want, there's a slack, discord, and https://community.openstreetmap.org/

Check out https://nominatim.org/

No worries about the caps, just want to make sure conventions are understood. Another convention is to expand abbreviations, for example, West Maryland Avenue (not W or Ave). I think it's up to the osm client to present and differentiate addresses. You would just need to add more details, like city (or county, state, etc)

Again, city not needed. And all caps is reserved for SHOUTING :-)
Keep mapping! Ask questions if you need assistance.

Hi, MS, welcome to OSM. the addr key is used for building address info. Streets don't need this, and it should be removed. Check out the wiki at: osm.wiki/Key:addr:*

BMacNeal,
This change broke the white clay creek preserve relation. Fixed in changeset below, please verify.
osm.org/changeset/161212595

Stretch, noticed Endowment Place relation broken, fixed it in osm.org/changeset/161173551

thanks for the corrections! especially 1515 wynsam.

ok. thanks for investigating.

Aleh, can you look at the streetside imagery for this street? It seems to show "Place" and not "Street". Also, all the houses from city data are Place, so now they are out-of-synch with your change. Here is a link to the imagery:

Grawat, should 1328735779 also be name=North 16th Street?

HI HIJ!, welcome to OSM. thanks for adding all the buildings and pools. Quick tip, most buildings have square corners, if you press the 'Q' key when the building is selected, it will square the corners and look nicer. Keep mapping!

Tomato_paste, Welcome to OSM! Thanks for the fixups, and the other items you've been adding. Good job, keep going. If you have any q's, just ask. -wg
