I've removed the 80 fictional parks.

Regarding the paths, your new pedestrian way Way: 795845600 runs by and joins to an existing footway Way: 294405002, are there two paths? Or maybe three, if your New River Path (Way: 795840159) is supposed to be a path. Are there really three verifiable ways here that can be seen or ascertained on the ground?

Could you please have a look at resolving these problems.

Regards Bernard.

Hi, Welcome to OpenStreetMap.
A few anomalies I can see.

First your waterway Way: 795767125 looks like it duplicates the existing waterway Way: New River (22588507), and is there really a dam (Node: 7443875485) before the tunnel (Way: New River (109624838))? You've also drawn a waterway bank (Way: 795758140) but tagged it incorrectly natural=water
water=river. You've also connected the bank to the your new and the existing canal centreline.

Hi, Welcome to OpenStreetMap.
There's guidance for mapping a park here :-leisure=park
Generally the overall outline is drawn and tagged as leisure=park. Individual areas within the park can be drawn tagged surface=grass, or whatever.

Hi Welcome to OpenStreetMap.
Minor adjustments to paths and tagging, Added ref number, removed name.

Hi,
Welcome to OpenStreetMap.
There's a best practice for tagging schools set out here :-amenity=school I've re-tagged the school building to suit.
I also squared up the buildings.
Very good first session of mapping.
Regards Bernard,

Hi, the school name is on the overall premises outline, I've tagged the three buildings as building=school.
Regards Bernard.

Placed tags from POI onto building.

Esri imagery shows this as a pair of houses, thus I've removed the number and tagged as building=residential.
Regards Bernard.

Remove one building that's not there, square up building and add tags from nearby POI

Hi Welcome to OpenStreetMap.

I changed the tag from landuse=farmyard to landuse=farmland. Moved to farm POI to the buildings.

Hi Marcus,
First my apology.
I only use JOSM where you first pick barrier=fence then have the option to describe the fence type and height. So I had not come across a tag barrier=wire_fence before. I just tried barrier=wire_fence in JOSM and it is accepted.
It's a bit confusing also because two OSM Wiki pages barrier=fence and barrier=* advise to use 'barrier=fence and fence_type=wire'. Indeed one page advises to "verify if it could be tagged with another tag".

Sorry to have troubled you, Regards Bernard.

Hello Marco,

Hi Welcome to OpenStreetMap.
I've reverted your change as deleting an object removes it's history from the database.
If an object needs amending/moving please make adjustments to the original/existing object. Thus the existing history along with the history of your change is maintained.
Also your position joined the phone to the highway.
I've moved the phone to your new location beside Waddington Road.
Regards Bernard.

Hi Welcome to OpenStreetMap.
Squaring the buildings up makes the mapping look a lot more neater.
Regards Bernard.

Hi,
Tags for the fence Way: 794155176 should be barrier=fence and fence_type=wire not just barrier=wire_fence as that is not recognised or rendered.
I've amended that fence line, are there more?
Regards Bernard.

Hi, You've duplicated some sections of highway by placing Way: Rainford Linear Park (793197836) on to of existing highways.
Could you have a look and remedy this please?
Regards Bernard.

Hi, Welcome to OpenStreetMap.
There is access to Jackets Lane by cycle and motor vehicle, and the way has been mapped as an unclassified road. You can see on imagery that there is vehicle access to the digger hire premises.

Unless you can verify your changes, no bicycle or motor vehicle use and speed limit 5mph, then you ought not amend the way thus. It is quite right for you to give an opinion in the description tag to make folk aware of problems. Or even to map any verifiable obstructions. You could tag the part of the lane that is both unclassified highway and Public Right of way footpath.

Regards Bernard.

Hi, Welcome to OpenStreetMap.
I can see (from imagery) the position of a gate on the access road just north of a pond near to Oakridge Lane, I've mapped this adding access=agricultural to both gate and track.

I can't see where a gate is on Blackbirds Lane (I take it you mean the south end). Anyway OS Map and Hertfordshire Definitive map show the south section of Blackbirds Lane, (that you tagged as private) as being a way having public access. The existing OSM tagging states it as an unclassified road. Your putting access=private on the way implies there is no access to the public, which is incorrect. Yes the road may well be in private ownership as is almost all land (even highways) in the UK. But if you tag it as private you ought also tag the allowed access.
Further your private tag will hinder anyone in the future claiming any right over the way.
I've removed the private tag.

Regards Bernard.

Hi, Welcome to OpenStreetMap.

I added foot=designated, tweaked the path line a bit and joined it to the road at north end. It would be good to have the Council prow_ref number.

Regards Bernard.
