Hi Rob,
Using Google map data even derived data infringes Googles copyright. So it's best not to even mention Google when mapping to OSM.
I can see the western half is asphalt, I've tagged that half bicycle=yes, foot=yes, highway=service, surface=asphalt which I think is correct. The eastern half looks like a farm track, I've tagged it foot=yes, highway=track, tracktype=grade4
Track-types are described here :-tracktype=*

I hope this helps, please feel free to amend the tags to your knowledge bearing in mind that tags should reflect ground truth and be verifiable.

Regards Bernard.

Hi Welcome to OpenStreetMap.

Please don't make changes to the OSM database to suit your own purposes. Features added to or amended on OSM must be verifiable.

At least part of the way you tagged as grass is asphalt,and at least part is a route with public access, bicycle.

Regards Bernard.

Hi Owen,

I've removed the name, I had thought you meant it as a name.

Regards Bernard.

Hi, I removed the seemingly inadvertent tag ford=yes from your new track.
Regards Bernard.

Looking further another section of track Way: 792725403 is also drawn in part on top of existing highways and seemingly across fields.

Hi, I was wondering why Way: 803319027 is drawn across fields , woods and a stream where the imagery shows no sign of the track? It's also in part drawn directly on top of a footpath, Way: 27643475. Has the track been newly created, is it a new cycleway?

Curious Bernard.

Hi, I've amended the tags on the garden to OSM practice.

Regards Bernard.

Hi, You somehow created or left some untagged unneeded lines and polygons,
Way: 803511982, Way: 803511973, Way: 803511961, Way: 803511962 in this area. I've deleted them as that seemed easier than explaining to you exactly where they were. Please have regard to errors and/or warnings when uploading.

Regards Bernard.

Hi, Welcome to OpenStreetMap.
It's likely the road is not a public highway but it was not described as such. It certainly is shown on imagery. Does it exist as a service road through a gate to a storage area? Or maybe the area has been developed and the road removed? If it exists in some form it is a valid feature for OSM. Could you please comment?

Regards Bernard

A building polygon should outline the building not the residential area that is landuse. I've reduced the building to the building outline.
Regards Bernard.

Hi, your cycleways are duplicating existing highways thus with one highway on top of another routeing is difficult if not impossible.

I have removed the cycleway lines and the fictional bridge. Please take a while to learn how to properly add features to OSM, there is usually a way do almost everything.

Regards Bernard.

Hi, you placed part of Way: 803060759 on top of part of Way: 732249377. I've removed the duplicate highway section and tagged the service road to accommodate the RoW.

Regards Bernard.

Hi, I removed a couple of duplicated highways here. Way: 803365344 and Way: 803365343
Regards Bernard

Hi, Please be careful to join your paths to the highways they meet, I've just made three joins. I also remove a couple of untagged single nodes.

Regards Bernard.

Hi, Sorry I'm late getting back to this.
I've now remove the duplicate sections of path, tagged the relevant highways as designation=public_footpath
foot=designated
highway=service
bicycle=no
horse=no

I had to tweak the lines a bit but I think it's OK, please have a look, let me know if it needs changing.

Regards Bernard.

Hi, Thanks for correcting Way: 296927558

Hi, Welcome to OpenStretMap.

I've made a few amendments.
Removed duplicate section of college road and path.
Move residential and park areas off of highway line.
Remove added nodes from Fleet.
Move areas off of highway center lines.
Remove unnecessary multipolygon (chapel), redo chapel.
Amend outline of Denyer House.

Regards Bernard.

Hi, Welcome to OpenStreetMap.

Yes you inserted the bridge OK, the problem was with the path. I've joined the path Parson's Drove to the road Parsons Green. All is OK now.

Regards Bernard.

Hi, Welcome to OpenStreetMap.

Re requested review.
Your fictional area of sand covering many other features in that area has been remove.
Regards Bernard.

Hi, Regarding the BT Openreach building.

It is OSM good practice not to delete and redraw features that need amending because all the history of the previous mappers and their amendments are lost. Better to amend/edit the existing feature, the history of your changes will then be added to that feature in the database.

I have made a few amendments to show how features are better represented. I squared up the building, then removed the incorrect section of the footprint outline where you attempted to section off the internal area. Then added the internal area, a courtyard squaring it with the building outer line. Then created a multipolygon relation of the two areas to show the building with a cut-out interior section.
Please see this page for how to create buildings with internal cut-out areas (multipolygon relations) :-https://learnosm.org/en/josm/josm-relations/

Regards Bernard.
