These tags are artifacts of a long ago import. Many Massachusetts mappers, but not all, agree they should be deleted. I try to delete them from highway ways and nodes I edit. I'll consider deleting them from landuse or leisure ways as well. What we need is a mass removal. Thanks for the comment. Alan

Not an import. Reworking bad data from 2009. Old polygons were from digitized maps and poorly aligned. More recent data is now available which is replacing old one polygon at a time after review. I'm lobbying our local community to remove all these massgis: tags that came with the import.

Not an import. In Massachusetts we have about 20 dumb keys that were introduced during the original import in 2009. see osm.wiki/MassGIS

deleted tags, added new

Thanks, tags have been deleted.

Nice catch. Yes, that was my mistake. I remember now that I was trying to use the iphone app go map!! .

Thanks for catching that error and notifying me. I found that I had another similar error which I have corrected.

Thanks for breaking up these ways. It made it a lot easier for me to add road names from new TIGER data.

I can understand how the comments are confusing. In Massachusetts did have an import of land boundaries many years ago. Problem is that they were all skewed. We use newer imagery to re-align them.

Sorry, this wasn't an import. I made a number of local changes then did a couple map roulette fixes and they probably got caught up in the same changeset. That accounts for the wide distribution.

What is the source "HS"?, there is now good bing imagery available.

Nice change. I added amenity=police to the building. Thanks for mapping.

Nice fix. The old TIGER census data showed Cypress Road extending southward. That's probably the source of the road you deleted. Thanks for mapping.

This building has no width. Seems to be a shop but I cannot define it with the imagery.
Nice mapping in this area.

These buildings don't seem to have any relationship to the bing satellite images.

On purpose. The GIS manager in our town has given me a shp file for new buildings. That field the date he updated the building. I'm using his date to keep track of the geometry as I replace them one at a time. In Massachusetts all our buildings were imported years ago and many have been torn down and rebuilt.

two parking lots were drawn by a single way. This caused a self intersecting way error Invalid polygon
Self-intersection[-71.1326805523277 42.5562496687046]
I split them.

The cemetery overlaps a large housing area and a lot of open land. It should be re entered if it really exists with a more detailed boundary.

Hi, Welcome to Openstreetmap. There is a better tag for a swimming pool. I've changed your "lake" to leisure=swimming_pool. There is a good list at osm.wiki/Map_Features

I'm not sure changing from building=yes to building=house will make much difference. I see your using potlatch now. JOSM is the one I use.
