Is it really called "Yurt?"? Or are you suggesting there may or may not be a yurt here? way/1109780398

Hm, trademark infringment?

New aerial, huh?

This is a service road for the canal. Definitely not for a house.

The links only mean that there is a wiki entry for the tag. Remember that OSM is any tags you like, so you can invent a new one if no tag exists for something you want to describe. However, using recognized tags ensures easier comprehension of the data.

Some common tags may not have entries, which should be kept in mind.

What is the meaning of residential=residential?

Check the suffix on way/932706476

Again, please expand road suffixes.

Bad data values as well (start date 1970/01/01 = beginning of Unix epoch)

Bing is outdated. That section of the road was torn up for a subdivision under construction here. Please revert this changeset.

The vast majority of these buildings were destroyed in the Camp Fire. Think before you map, please!

I guess they are changing the collector names after all. Addresses have been changed.

I think the utm_source is from Google My Business. The website is a page offered by Google Maps, so it makes sense that a link copied without paying close attention would have that tracking parameter.

Detached. Forgot to edit the boilerplate. None of these are mobile homes.

Square doesn't turn shapes into squares, it just turns near-right-angle corners into right angles. Round objects (like kidney-shaped pools) will get messed up, but rectangular pools (even with unusual corners) will be made more accurate for it. Just check the shape after performing the operation to make sure it is still accurate.

Not all presets need to have all fields filled. As there is no "no horses" sign on way/1113526273, there should be no horse=* tag at all.

When drawing features with right-angle corners, like buildings and most swimming pools (e.g., way/1113751994) make sure to press Q to square them.

Welcome to OSM!

A few things from this changeset:

Don't use names as descriptions, like on way/929534812 and way/1113411405. Not all features need to be tagged with a name.

Some of the features were duplicated, such as the Wendy's and ICCU mapped as nodes under construction. Make sure a feature isn't already represented in some way before adding it.

A lot of presets add tags indicating that an area is a building. For way/1080134565, this is incorrect. The entire lot on which the restaurant is located has been marked as a building. For features like that, the building itself should be tagged with the restaurant information.

Hope this helps! I've made a few of the more advanced corrections myself.

Generally, addr:unit should just be the number itself and not the unit type (Suite).

way/772834576 is semidetached, not detached
