Something about how you're editing is occasionally creating duplicate objects. This edit duplicated the bicycle parking and other objects around Conflux Brewing, and a previous one doubled up some of the roads and amenities of a campground.

I've cleaned them up, but it's something to watch out for in the future.

I'm not sure what you were trying to do here, but you've tagged some sections of rail with the tags "Lincoln=County" and "Port=Authority".

There's an existing marker for a "Walla Walla Baking Company" at this location. Are the two the same business?

Best practice is to spell out road names in full. It's easy for a computer to abbreviate a name if it needs to save space, but it's considerably harder to automatically expand abbreviations. "N" for "North" isn't too bad, but does "St" mean "Street", "State", or "Saint"?

Vandalism is something that everyone should understand. It is wrong to delete a school from the map in order to promote your business.

This is officially a *right of way*, which is not the same thing as a street. It's got a line of boulders across it near the Rosamond, and the stretch past the boulders is heavily decayed, with grass growing in the cracks, and decades of dirt and pine needles covering sections of it.

Unbuilt or abandoned right-of-ways are common in the city's larger parks: Manito, Palisades, High Bridge, and Finch Arboretum all have them. Riverfront Park has the opposite situation: Washington, Stevens, and Post are all built on park property, not public right-of-ways.

It's pretty clear that this *was* the south end of Woodland before I-90 was built, but it was abandoned as part of the freeway construction, probably in the early 1960s. If it's still on the city's map, it's because nobody's bothered to fill out the paperwork for removing it.

You appear to have forgotten to tag most of your buildings, leaving them as bare areas. I've fixed it, but it's something to keep in mind for the future.

If you're going to be adding buildings in the Spokane County area, try using Esri World Imagery as your background imagery. It's much sharper than Bing -- almost sharp enough to map the shingles on a roof.

Are you sure this is grassland? It looks pretty forest-like to me.

I don't know about that one, but the Rusty Moose is a pretty clear "amenity=restaurant, cuisine=american".

I think you're misinterpreting the "ways with long segments" issue: the problem isn't the length of the way, but the lack of nodes. When someone queries OSM for the geometry in an area, the OSM server finds all the nodes in the area, then looks for ways and relations associated with them. If a way passes through an area but doesn't have any nodes, it won't show up.

The correct fix isn't to split the way, but to add more nodes. Somewhere between two and ten nodes per mile for a straight line is reasonable: more in dense areas like a city where someone's likely to download just a small part, less in sparse rural areas.

It looks like you forgot to include the "building=" tags on this batch.

I'm trying to figure out the reasoning for some of the "fixes" you made here. For example, you sliced up the Sanpoil River into about a dozen pieces without apparent reason; you did a similar split to part of the Ferry County/Okanogan County boundary. In other places, you've made apparently-trivial changes to way geometry, and I can't figure out *what* you changed about a power line near the Spokane airport.

Actually, our most important job is to make an accurate map. Sure, deleting keyword-stuffing is satisfying, but translating it into OSM tags makes a better map.

Unless something's changed since the last time I drove it, Wellesley curves around to become Valley Springs, with Havana and an unsigned road branching off to the left. It's not a squared-off intersection like you've drawn it.

Could you do your stuff in smaller pieces? Scattering it out like this makes it show up in the history view for everyone in the United States and most of Canada.

A more descriptive comment than "Stuff" would be nice, too. Something along the lines of "Traced building outlines" or "Added parking lots", perhaps.

"Road closed" isn't a reason to delete a road, it's a reason to mark it as "No access". "Road gone" is a reason to delete, but all the aerial imagery I've looked at still shows this.

Thanks for the source. Looks like they might actually be going with that route -- the estimated costs are about right for a large bridge and some significant cuts.

Are you sure this is a service road? In the available imagery, it looks like a fairly standard two-lane road to me.

Are you sure some of these are tracks? Smyth Road in particular looked like an ordinary rural gravel road when I drove past it two years ago.
