Hi Kaore,
are you sure there is a golf course at this place. I've been there multiple times and I haven't seen it.

When editing building footprints, please move the individual nodes of the existing object. Do not delete and re-draw the object. By deleting, all history and important tags are lost.
I had to revert your changeset.

Sorry had to revert your edit. The grass field exists on top of the undeground 41 Sachem building.

Hi RD1.
In your edit, you disconnected Argyle Street from Winchester Avenue and bunch of other service roads on the parking lot.
Was there a construction work? Because on the imagery everything looks connected.

I would be difficult to fix the data so I reverted your changesets 34742741 and 34736781.

And regarding your motivation, just remember that we don't map for the renderer, we map reality.

Hi RD1 and thanks for contributing to OSM.
I would like to ask you about purpose of your edits.

-You changed Morgan Lane type from "tertiary" to "residential". Any reason for that?
-You deleted a bridge on Morgan Lane over I95. The bridge is there and still functional.
-You deleted area that marked Yale West Campus. Reason?
-You deleted Heffeman Drive and replaced it with a unnamed service road. Are you sure this road does not have a name?
-You disconnected Entrances to West Campus from former Heffeman drive.
-You changed the type and removed the name of eastern part of West Campus Drive. Reason?
-You changed a piece of entrance road to tertiary way/360973798

According to this, Schwartzman Center opens in 2020.
Reverting.

Smilow field center is the building next to the are you tagged.
Fixed.

Hi,
sport center not correctly tagged as amenity=university.

Hi,
are you sure that this is now called Schwarzman Center?
All I can find is University Commons.

Hi Sei Han,
Temple Medical Center Building is already traced in OSM. It is the larger building you drawn your new building into.
Please always double check that the object is not already in OSM before you upload.

Again, You drew building on top of another building.
I fixed it for you.

Hi,
I don't see how this geometry has been corrected. You just drew new buildings on top of already existing building.
btw: what is special about the newly drawn parts that they have to be separate buildings?

Hi,
you just drew a building over a part of existing building. + Your newly drawn building is less precise. Can you please fix that?

Hi,
you just drew a building over a part of existing building. Can you delete the overlapping part?

Hi,
and thanks for contributing.
1) Are you sure that address of this location is 41 Sachem Street?
2) amenity=university is used to tag whole area of universities. Yale already has it's area tagged. I would suggest deleting or retaging.

Oh great catch. Sorry, I didn't realize they moved it.

Hi,
I don't think that Exit 1 is positioned where you placed it. It should split from I91-S even before Chapel street. Also the the ramp does not merge with I-95 off-ramp from left but form right as it was in the previous version.

Super, diki.
Ak nabuduce zistis, ze je nejaka znacka dokoncena, tak jej mozes zmenit tag na complete=yes. Lepsie sa tak potom hlada, co este treba zmapovat.

Tato znacka vyzera byt dokoncena.
complete=yes?
