This wiki page is even better as it offers more detail:
natural=coastline

Hiya 2Woy,

Welcome to OSM!

The water area beyond this line to the West is treated as part of Broken Bay which is a natural=water + water=harbour relation.

Link: relation/1256210

The coastline tag is a bit of a special case as it not only defines the start of the ocean, but it also defines landmasses within the ocean itself (such as mainland Australia). Breaking the coastline by removing sections can cause problems.

I could see how you could mount an argument to include some or all of Broken Bay inside the coastline (possibly after community discussion) but removing a section without any discussion and other fixes is not the correct way to go about this.

More on the coastline tag, here: osm.wiki/Coastline

Doh! Thank you for fixing this.

I just noticed this while darting about the map and was wondering who did all this beautifully detailed mapping out here. Of course it was you. Nice work!

Hi Matt,

Welcome to OSM And thanks for your recent additions.

When it comes to the name tag, you should normally reserve it for the actual names of things, so a private pool doesn't need to be called "name=pool" if it's already tagged correctly, and each property doesn't need the name "Property 1" "Property 2" and so forth.

Hi Prefix,
You removed this parking lot: way/403557987/history In this changeset, however you left all of the parking aisels (and added additional tags to them) is the parking lot actually gone or was this an error?

Hi Davis,

Welcome to OSM.

This changeset created a few errors and duplications.

At a glance, the following features were already on the map before you added second versions of them:
-Baker Hall
-CU Student Recreation Center
-CU Folsom Field Stadium

OSM works on the idea of one feature, one osm element, you can read more here:
osm.wiki/One_feature,_one_OSM_element

Please reach out if you need some help setting things right.

Hi Megan,

Please check the errors that iD presents you with before uploading. OSM is a live map so any edits you make are accessible to everyone.

This changeset has 14 errors for crossing highways.

Some of the paths you added intersected other existing paths, buildings and roads, and don't seem to relate to what is on the ground

Hi Quach,

Welcome to OSM!

Your "fishing path" currently runs through the water - is this correct?

Please also note that the name tag should only be used for real names of things, not descriptions. It's 100% ok to leave the name tag blank.

Hi Vincenzosaurini,

In this changeset you seem to have accidentally dragged some footpaths the whole way across campus. I've fixed them now.

The iD editor would have highlighted those errors for you before you published them, so it might be a good idea to check errors before uploading changes in the future.

This is a public map that is used for many real word purposes. Please do not add fictional elements to it, they will be removed.

Hi Sinviana!

Welcome to OSM and thanks so much for your recent contributions!

I just thought I'd check this park: way/867170745

Are you sure you got it in the right place? I can't see any evidence of a park here and it looks like it partially intersects someone's front yard.

This is how we define a park on OSM:
leisure=park

Hello!

I see that you are mapping the Seto Inland Sea as a relation.

As it is currently mapped as a series of "outers" forming an incomplete ring relation. This triggers a number of errors on error checkers such as OSM inspector, and can also cause many renderers to attempt and close the ring and consequently include land in the bay: https://imgur.com/Fh5A9dl

My suggestion would be to not tag this feature until it is complete, or to upload it only once it is complete.

Don't you just hate when that happens!?

If you're at all familiar with the location: I did the best I could, but the tagging here could probably use a little refinement and I'm not sure if the address is 100% accurate with everything in the complex being a single house number.

Hi Joshuathor,

Welcome to OSM and thanks for your recent additions to the map.

Please keep in mind that this is not a residential directory. It's best to avoid listing who lives in certain houses and also to limit the mapping of private residential property to very basic details such as permanent buildings, driveways, and larger pools.

Thanks again for your contributions! Happy mapping.

Hi CC T

Welcome to OSM!

This changeset seems a little strange - I'm not sure I understand what you're trying to add here.

You mapped townhouses as a stately castle, and you created a park (where there doesn't actually seem to be a park) with a name that is just coordinates.

Hi Sourajit,
It seems like you accidentally placed this park in the middle of the ocean: node/8057572861

May be a continuation of fictional mapping by the user austin51 who was banned after making similar edits in this general location.

Hi AwsCc10

Welcome to OSM.

The edits you are making don't appear to relate to anything, are you able to explain them?

Thanks!

Hiya dustybus157!
Can you please help the other editors in your area out by leaving valid changeset comments please? Emojis are fun, but they give us no idea about what you're actually adding!

Also, don't forget that you can square up buildings by pressing "Q" or right clicking them and choosing "square"
