Glad to help

South Pembs is especially complicated as the original names would be English or derived from Norse or Flemish. I don't like the idea of making up Welsh names for places that have never had them.

It also seems redundant when cy:name and en:name are the same as name.

Can you tell us what the original research was? I've never heard it called West Williamson.

What is this supposed to be?

I hope Tan cottage has ample fire extinguishers.

In addition the OSM maps are rarely accurate. In my experience they can be off by tens of metres. Mapping by walking and recording with a GPS is the only accurate way to map paths.

I'm not sure that deleting the track is correct solution to a routing problem. It would be better to mark the track private or somesuch.

You appear to have some of the speeds in Km/h. We use MPH in the UK so although the speeds are technically correct perhaps using MPH is better for the UK.

Your garage seems to be in the middle of the road. This is very unlikely to be it's true location. Can you amend this edit to show the real location?

No, you can just change the tag.

Hi and welcome to OSM. leasure=park is the wrong tag for this feature. Benches have their own tag.

I agree. I apologise.

I agree. I was probably a little too harsh in my comment.

Since Zopes is a Pokemon go player I think any added parks should be regarded as suspect.

Welcome to OSM. Your test seems to be a success. :) However unless "45 Matthew Lane" is the actual name of the building then it should be tagged with it's address not it name.
Keep going until all the houses are mapped :)

But why did you remove landuse = recreation_ground ?

You seem to have flooded this estate again, have these houses really been demolished and replaced with a lake? If there's no lake here please don't map it as such.

Map each pond separately.

This is a map not a business directory. Is this an actual business premises that people can turn up to? Will there be free coffee?

Is this a public footpath?
