Hello! You use the key ref:usfws in combination with the source (Fish and Wildlife Service). I assume the correct spelling of the key could be ref:US:fws.

Please have a look at ref=*. The keys in the group ref are supplemented by a country (or possibly organisation) abbreviation for better validation and to avoid different meanings. This is followed by a detailing according to the person responsible for the data, in your case as suggested ref:US:eff. The prefix unsigned only indicates that the value cannot be found on the mast (if a mapper wants to check it). In this combination they are of course new, but the structure allows an interpretation of the meaning even without detailed knowledge.

Okay, it seems unclear whether the TowerX value is also present on the mast or just an internal numbering in the data set. Personally, I would mark values from the mast as ref:US:eff and use the unsigned_ref:US:eff key in the second case. I personally see the source:ref key as problematic because the attribution key was used instead of source. But you are welcome to discuss this on your standard channels, but please don't invent any new formation logics (such as source:eff_ref).

The additional note for the values of the ‘surveillance:type’ key is also appropriate. The standard values are written in lower case. And AI is not a visible sensor but describes the data processing of the recorded data. I would generally delete this value, as it cannot be validated.

Hello! Please have a look on node/12776598795. What is the mean of the tag source:eff_ref = Tower527? Did you mean the key ref:eff (or better ref:US:eff)?

Hello! What is the mean of the tag sharko = yes?

Hello! Better import notation with note="Import see osm.wiki/Import/Hendricks_County,_Indiana" instead of the tags
import = yes
import:page = wiki: Import/Hendricks County, Indiana

Welcome to OSM! Please use the tag "building" = "yes" (not "building=yes" = "yes". And there is no necessary to add a name (tag "name"="Building")

I didn‘t change your version! Is it usual for you to accuse the reporter of vandalism when your mistakes are pointed out?

see changeset/165209623

The correction made by mueschel without asking is correct, I would add a noexit=yes according to the meaning of the sign.

Welcome to OSM! Please discuss with @Comino the deletion of currency:XBT=yes (see changeset/165135347) instead of using short cuts (cy:XBT instead curreny:XBT)

Also note that you have to make an entry for the company (node) and not for the site (area e.g. actually building according to aerial photograph).

Hello! Why did you change description=<value> and description:he=<value> to Alt_description:he=<value>? The prefix alt_ means alternative to an existing (!) key. Apart from the fact that the leading letter (reading from left to right) is written in lower case, the key is missing. So why did you make this modification?

Hello! Please have a look on node/12770962550. What is the mean of the tag 7x = 1/2016?

Welcome to OSM! Please notice the equal sign is the separator between the key and the value. It can't be part of the key. Please correct this!
