Hi BinkalB, your changeset comment says "added building", but edited a place node as a clock. Review what you edit before you hit save.

Hi monsoonheat, welcome to OSM. Roads shouldn't cross buildings, so avoid that when mapping. JOSM will always show that as a warning, so fix them before you upload.

Hi BinkalB, building=1 is not a valid tag. Use building=yes

Hi Mensah Silas, welcome to OSM. Please take a critical look before you upload/save what you map. I doubt you'd find a building in the middle of the road.

Hi Nsumba Joshua,
Welcome to OSM. The name=* tag is for the name of the object mapped, but not the name of the mapper. Take note and avoid doing that in future edits.

Hi halfdbeecreativestudio, welcome to OSM. Addresses are separate objects. Please add a new node for new objects.
I've fixed this, but take note for future edits.

Does this school no longer exist?

My comment on your earlier changeset also applies here. Changes reverted via changeset/183192620

Hi Saykay 04, buildings are mapped as polygons with the tag building=*. Adding historic=building nodes on already mapped buildings is not right. These changes have been reverted via changeset/183192409.

Hi Tema check check, welcome to OSM. If you only wanted to change a name, you didn't have to edit the geometries. Your changes have to be reverted due to errors created via changeset/183192058.

If you want to add your business to the map follow the introductory tutorials on learnosm.org. If it's already on the map, you can share a link to it and I will help fix it accordingly.

Hello Helena Eshun, you have created all these nodes at the same position. Most of which already exist. Please pay attention to existing data when mapping.

Did you intend to add Agogowa as a name? natural=Agogowa is not a valid tag.

Hi kwarko27, in OSM name=* is the name only. Location is not part of the name.
osm.wiki/Names#Name_is_the_name_only

Thus, the name will be restored to the previous version.

Address nodes are supposed to be standalone. Create a new node for new objects. I've corrected this one but take note for future edits.

The shop might have moved, but I believe the building is still there. You should have kept the building polygon and removed the shop tags instead.

You can keep the metadata in your privately stored version. It's not needed or useful in OSM. Each object in OSM has its own metadata, which is not added to the tags.

creation_date, Creator, Editor, and surveyor_name all need to go.

ambulance, electricity_available, level_of_care, and staffing are not standard keys. Check amenity=hospital, amenity=clinic, healthcare=* for tags that may be appropriate.

I think emergency=no is better suited for ambulance=no. Creator can be replaced with source=*.

Please check the links for better tag combinations.

Hello Seemaslimits,
Welcome to OSM and thanks for your contribution. Kindly note that OSM uses standardised tags to map features, e.g. healthcare=* for health facilities, which you have rightly used. However, metadata like creation_date, edit_date, etc., that you have included in the tags are not necessary. After a survey, you need to clean the data and upload only what is necessary for OSM.

Hi Beatrice Agboglah, welcome to OSM. In this changeset and the previous one, you have deleted building polygons and replaced them with subpar unorthogonal polygons.
You are currently not improving what exists, so I will advise you, as a beginner, to focus on mapping buildings that haven't already been traced.

Hello Abdul Rahman78, welcome to OSM.

You need to understand the changes you're making before saving them.

Do not delete mapped buildings with all attributes, replacing them with low-quality ones.
Tracing over existing buildings is also unacceptable.

Understand the highway=* tags before using them: the roads within KNUST are not highway=primary.

Try to fix the warnings that are highlighted when saving your changes.

There are many issues with your changeset, so I have to revert it. As a beginner, focus on adding data at places where there is none. Modifying existing data that you may not fully understand may cause more harm than good.
