Hello There,
You've mapped the park over two buildings. Have the buildings been demolished? If so the buildings should be removed or tagged as demolished.
Regards

Hello and Welcome to OpenStreetMap.
I have removed your POI as it is already mapped. I have added your tourism=attraction tag to the existing POI as it was missing and may have led to your addition.

Hello and Welcome to OpenStreetMap.
I wonder if the guest house is really called "HOME" and if it is actually situated on the corner of a street. Could you please better place the POI and possibly correct the name?

This feature House of Abderahman is in the garden behind Foulden Road. There is not to my knowledge a hotel on Foulden Road. I suspect this is probably where you or your friend resides. You could map the house where you live, that would be OK. But this fiction should be removed.

This feature House of Yousef is not placed on Jade Close. There is not to my knowledge a hotel on either Jade Close nor Marble Drive. I suspect this is probably where you reside. You could map the house where you live, that would be OK. But this fiction should be removed.

Hello There,
I reverted the name change from your destination/origin information because Lea Valley Lines is the name not Enfield - Liverpool Street Line.
The destination and origin information is already contained in the route relation.

Hello There, i think something went wrong with Jennings Pool by the looks of it. Can I help? Can it be removed?
regards Bernard

Inadvertent un-tagged mapping removed. Added back wood area to your park, the area can have two or more descriptive tags.

Hello, you haven't actually deleted the building or park, you've just removed some tags to them.

Hello There,
As the areas are mapped the name Perivale Wood Local Nature Reserve appears three times on three areas. Do you think that, as the two meadows are mapped as within the Perivale Wood Local Nature Reserve, they might just have their individual meadow names. Thus avoiding repetition.

Hello and thanks for joining the two paths. I had alerted the new mapper to the problem with a comment on his changeset (changeset/46028966#map=19/52.63163/1.31219). He responded but due to your quick correction was not able to see un-joined ways.
If you notice a newbie has been alerted to their problem could you give them a chance to see and correct things please.
When I make these sort of comments I bookmark the comment and look again after several days. If there's no response then I
make the corrections.

Thanks and Regards Bernard

Hello Andy, The problem was fixed yesterday by mapper dmgroom_ct so you were unable to see the un-joined ways.

No problem now and thanks for your additions. If I can help in any way please just ask.
Regards Bernard

Hello and Welcome to OpenStreetMap.
The two footways are not joined to each other. Could you verify or not that there is a continuous way through on the footpath from Gas Hill to St Leonard's Road? If so then the two paths should be joined.

Hello Dyserth, the above link show the geometry layer of problems in OSM mapping including area intersecting points. There are several views that can be selected giving many layers of differing problems.
Yes self intersections are where an area outline doubles back on itself.
I have corrected a large number of these so you shouldn't find any at the moment.
If I can help with anything please just ask.
Regards Bernard

Would you then correct the speed limits on the estate please?
It would be wrong for OSM, (the best map in the world), to knowingly contain wrong data.

Hello There and Welcome to OpenStreetMap.
I really don't know how you came to map your POI so far away from Raleigh. You actually changed the address of a building mapped in Dagenham, London, UK.
I have reverted the change so no harm is done here. If I can help in any way please just ask. Good luck on your next try

Pointless POI from maps me removed

Hello Dreamer. This POI "Buckingham Palace" is actually along way from the Palace.
The Palace is already tagged as tourism so no extra tag is needed there, would you please then remove inadvertent POI?

Your POI "Greenwich" is not needed either as the place is already mapped, the place itself is not really deemed an attraction though there are many nearby attractions. Could this also be removed?
