I'm happy to help. I'll message you on osm slack.

Hello ConradWard,

Thanks for your contributions to openstreetmap.

I noticed this changeset as some of the relations showed up on osmi as possible errors.
https://tools.geofabrik.de/osmi/?view=areas&lon=-70.74545&lat=43.96406&zoom=15&baselayer=Geofabrik%20Standard&overlays=duplicate_node%2Csingle_node_in_way%2Cduplicate_segment%2Cway_in_multiple_rings%2Cintersection%2Cintersecting_segments%2Cring_not_closed%2Ctouching_rings%2Crole_should_be_inner%2Crole_should_be_outer%2Cinner_with_same_tags%2Cways%2Cduplicate_node%2Csingle_node_in_way%2Cduplicate_segment%2Cway_in_multiple_rings%2Cintersection%2Cintersecting_segments%2Cring_not_closed%2Ctouching_rings%2Crole_should_be_inner%2Crole_should_be_outer%2Cinner_with_same_tags%2Cways

At a glance, there are a few things you may want to look at.
1) the relation/16218293 is a multipolygon with no other tags (e.g. landuse, forest, etc). That is unusual since it is a now an object that doesn't designate anything. The same could be said for some of the other multipolygons in this region including 16219408. I think they are not really achieving what you had in mind.
2) perly pond way/150511049 (as well as several other ways in this area) is a member of 10 relations, including 3 natural woods and 1 managed forest. I suspect that's a few more than necessary.

Hello,

What is this S.P.A.R.T.N Administrative Boundary? It doesn't seem real. Send me a reference and I'll be happy to put it back.

hi t2editme,

For the 3 ways that are part of the Jay Dam Multi-polgygons I think that you meant to make the roles outer rather than inner.

-scarapella

hi t2editme,

I think in this edit you have the inner and outer polygons roles reversed. You can use some of the validation tools such as OSMI to check your polygons

Hi t2editme,

On this change set, I think you want both buildings to be outer rather than inner.

Hello t2editme,

Can you help me understand why you changed way/1159951756 from natural=wood to place=island? I don't see a reason to remove the landuse tag, and the place=island is redundant with the existing way for Greenlaw island 107263908.

Hello t2editme,

Thanks for your contribution to openstreetmap.

I think if you look atRelation: 15601638 you might find the two inner ways should both be outer ways. Alternatively they could both be simply standalone polygons with amenity=parking rather than part of a multipolygon.

Hello t2editme,

Thanks for your contribution to openstreetmap.

I think if you look at Relation: Searsport District High School (15461215) you might find your inner and outer ways in this relation are reversed.

Hello t2editme,

Thanks for your contribution to openstreetmap.

I think if you look at Relation: Curtis Hall (14889374) you might find your inner and outer ways in this relation are reversed.

Indeed, looking at it now the Gulf of Maine Relation is… substantial.

Happy mapping,

Hi t2editme,

Thank you for your contribution to openstreetmap.

Looking at this change, it seems like it left Bar Harbor (relation/13332224) as an un-closed multi-polygon.
https://tools.geofabrik.de/osmi/?view=areas&lon=-67.02397&lat=44.95383&zoom=14&baselayer=Geofabrik%20Standard&opacity=0.85

Would you mind checking?

Thanks,

Hello Mainelymapping,

Thank you for your contributions to openstreetmap.

Looking briefly at this change set, it seems you've changed the Gulf of Maine (relation/13663366) from a Bay to an Islet. I admit i didn't look too deeply, but intuition tells me that the Gulf of Maine is more a Bay than an Islet.

Cheers,
scarapella

Hello t2editme,

Thank you for your contributions to openstreetmap.

In this changeset, it seems you changed a number of boundaries. This seems to have created several unclosed multi-polygons and added boundary lines that do not align with the official maine township map.

For example, we can see that the town of argyle now is an unclosed multipolygon
https://osmose.openstreetmap.fr/en/map/#zoom=13&lat=45.0679&lon=-68.6258&item=xxxx&level=1%2C2%2C3&issue_uuid=dc03e875-3ed6-3143-0ce1-ab7be859ba4c

and the introduced way/1168144686 does not align the maine township boundaries.

Hello Bkissin,

No worries. An BTW if it's easier for you to just repair, no problem at all. I just proposed a revert as it's what I would have done, but then you do lose the work you put into defining the wooded area.

The (only) way I know how to revert (which is inevitably because i've screwed up something :D ) is to use the revert ui
http://revert.osmz.ru/

Cheers,
Sean

you can also see how your edit removed some of the wetlands previously drawn such as

https://pewu.github.io/osm-history/#/way/1111192735

so overall this changeset degrades the information that was previously on OSM. I would recommend reverting this changeset.

Hi Bkissin,

Thank you for our contribution to open streetmap. I noticed this changeset for 2 reasons. First it seems like you use multiple values for landuse. I don't know that this is a common convention as the renderers don't know how to show this area. It also flags an osmose QA rule.
https://osmose.openstreetmap.fr/en/map/#zoom=14&lat=45.15299&lon=-68.27428&item=xxxx&level=1%2C2%2C3&issue_uuid=24d6f789-d869-dacb-d6cd-19d1adcf0ade

Secondly, it seems like there are some duplicate segments flagged on osmi
https://tools.geofabrik.de/osmi/?view=areas&lon=-68.27309&lat=45.15263&zoom=15&baselayer=Geofabrik%20Standard&overlays=duplicate_node%2Csingle_node_in_way%2Cduplicate_segment%2Cway_in_multiple_rings%2Cintersection%2Cintersecting_segments%2Cring_not_closed%2Ctouching_rings%2Crole_should_be_inner%2Crole_should_be_outer%2Cinner_with_same_tags%2Cways%2Cduplicate_node%2Csingle_node_in_way%2Cduplicate_segment%2Cway_in_multiple_rings%2Cintersection%2Cintersecting_segments%2Cring_not_closed%2Ctouching_rings%2Crole_should_be_inner%2Crole_should_be_outer%2Cinner_with_same_tags%2Cways

Yeah, it's really not super obvious sometimes when you're in the middle of making the edits if the multipolygon is well formed. I usually take a look at osmi a day or two after i've done a bunch of area edits to find what i've broken :-)

Bonjour La Voire de la Raison. Merci pour votre contribution à OpenStreetMap. Désolé pour le comment en Anglais. Je n’ai pas le vocabulaire nécessaire en Français.

I was noticing the way/1073918521 (highway=track) and similar nearby ways. I was wondering if they were not highway=track but instead some sort of avalanche or snow control structure like a ditch or a dike.

Hi bhietsch,

Thank you for all your contributions to OpenStreetMap.

It looks like with this edit you included the Massabesic Experimental Forests as part of the White Mountains National forest (e.g. way/733107487). I was curious as I didn't think these parcels are part of the White Mountains National Forest and I couldn't find an obvious link. So I was just curious how you made the link.

Cheers,
scarapella
