I just looked at the mapping here and observe that one path is not joined to the highway network at either end. The other looks like it should be joined to the service road.

Hello several highways that you've tagged as sidewalk to one side or the other actually have sidewalks on both sides for some sections, in one case there is a section with no sidewalk at all, left or right.

No problem. Welcome to OpenStreetMap.
I've looked at your mapping, made a couple of minor adjustments which I commented on for you to see.

Although the underscore is not incorrect it shows as not right in some tagging checkers. The colon does not present an anomaly and putting the numbers from (no number) 0 upwards keeps features numerically in line.
I think that makes sense!

Adjusted tag amenity numbering.

Hi, changed the dyke name to South Oby Dyke.

Hi, could you please verify that the four park areas are recreation areas that are open to the public?
If they are then it would be good to map the access to them.
If they are not then leisure=park is not a correct description to use. Perhaps landuse=grass/meadow or
natural=grassland would be better.

Hello and welcome to OpenStreetMap.
Just wanted to let you know that it's not necessary to always tag a two-way road as 'oneway=no'. A two way road without a 'oneway key/tag' is, (in the absence of a 'oneway=yes' tag) automatically taken as being 'oneway=no'
So although not being incorrect ''oneway=no' is not actually needed to show there is not a oneway section of highway.

Hi, I just changed the tag from park to recreation ground to better reflect the areas use.

Just wanted to add support to the decision to revert this changeset. It's very easy to make mistakes when you first jump into OSM mapping, I'm sure freefromsociety can make positive contributions. Just takes little research as to best practices first.

Hello There and Welcome to OpenStreetMap.
I've looked at what you've added to the database and see quite a few problems. The Howardian Hills: Area of Outstanding Natural Beauty is not just the area you mapped (please see the map here :- http://www.howardianhills.org.uk/about-us/).
There is no large residential area over the track leading to Wiganthorpe Hall.
The residential area at the hall could be better defined as could the wooded areas.
Are you sure there is pedestrian access down the drive to the hall?
If I can help in any way please just ask, in the meantime I await your response.

Hi, you need to tag the buildings (building=house) otherwise they won't show on the map. I've done the ones at Marzion.

No reply so removed some untagged ways.

Hello and Welcome to OpenSreetMap.
You might not be aware that OSM is a live worldwide database. Thus everything we add must be correct and precise. I have reverted your changeset/additions because they added ways are duplicates and somewhat fictitious. I hope you can understand the desire to keep OSM as the best, most accurate and up to date map in the world.
Regards

No response from the mapper so the changeset has been reverted.

Yes Welcome to OpenStreetMap, I have reverted your changeset because the duplicated ways would only serve to disrupt existing data. If you need any help adding something please just ask or read up how to do it properly. There's a help section here :- osm.org/help
Regards

Hi, I removed a path and an untagged way which looked totally out of place, I suppose you're still learning. Please remember this is a live worldwide database. Please don't upload stuff till you're sure it's correct. Regards & Thanks

Hi, I have reverted this changeset because it inadvertently dragged parish boundary, paths, roads ect out of original alignment.

Hello, I've tidied up the paths you marked and placed descriptive tags on them. They will now appear on the map.
I drew the paths from the Bing image, hope they are OK. How do the paths connect to the recreation ground and/or paths to the south please? Also do you know details of the nature trail area, boundary's etc and any other public access around there?
Regards.

Hi, I've drawn the recreation ground which is all foot access.
