Fixed a few so far: road alignments need a lot of tidying in this area. Will do rest in a sensible editor

Quick use of the measurement panel in iD suggests 10 metres is a more reasonable value, although the tree crowns are not uniformly round. It's worth binning values (e.g. using R) with this sort of data to find obvious outliers (Stereo first noticed peculiar values with Belfast tree open data. We know that usually there's an error rate with cadastral tree data, with perhaps 5% of records with one or more fields with incorrect data: species errors are common; trees which have gone very common;height, girth and spread values I've not checked in as much detail for reasons of practicality).

Hi,

No these look OK. Each group of modules is arranged as 4 rows of 10, so module count of 40 is correct. The idea of mapping each group separately is that it makes it much easier if one wants to convert them to areas.

At present a useful way of checking module counts is to draw lines along each axis and use the measurement tool to see how long they are. Most modules installed these days are 1.6 by 1 m, so look for multiples of these (in this case, each group is roughly 16 by 4 m). Older ones were 1.6 by 0.8 or 0.9 m, but new larger ones will screw up these rules of thumb. I use measurement when the actual count is difficult to obtain from aerial imagery (here the 10 columns are visible, but the 4 rows aren't).

When I did this mapping solar panels were not that easy to spot in London. I had a target of achieving 50% of the numbers present in the FIT data. Since then I've raised my game and managed over 95% for Wales. It does depend a lot on imagery quality, and it looks as though good quality imagery may become scarce in. OSM editors.

Any particular reason why you changed the Zion Methodist Church, Lees from a way to a node?

You have used the wrong wikidatabitems on the station nodes (town not station).

Hi Dave, Not sure why I missed the addr:city. Not sure about addr:suburb as "Clifton" is no longer part of the postal address & addr:suburb seems to be doing several things : marking actual suburb as part of the address, adding village name when posy town is not local, e.g. I think both North and South Clifton would be addr:suburb=N|S Clifton, addr:city=Newark.

I wasn't kern on thus tagging when it was introduced, and seeing a fair few addr:suburb=Clifton has made me more uneasy.

Jerry

PS. I'll try & find a road name for this one too.

Hi Bernard,

I'd appreciate it if you can avoid editing in this area until Wednesday. The roads around here are a mess and I'm trying to correct them as I can. However, I only have Vespucci with me, and a limited Internet connection so corrections can cause awkward conflicts which I find difficult to resolve on a phone.

I'm just off to investigate the mysterious library.

Thanks, Jerry

Hi, i removed this after copying any tags which differed the way I created a whole 14 minutes before you. BTW I think resolution of SwissSurface is superior in this case. I also changed fortification_type to castrum. Jerry aka SK53

Hi Dud, I don't think landuse=retail is appropriate for the Pottery. The house and business are owned by people I've known all my life, and it's always been a private house and garden, historically with much of the ground floor dedicated to craft workshops and only one room for sales. I think the shop is only opened occassionally these days (the owners are 7-8 years older than me) : at least it wasnt last time I visited 5 years ago.

I think my original tagging of shop=craft looks wrong now (described as craft supplies) : not sure of most appropriate tag, but given customer base is largely tourists, perhaps shop=gift, although the shop_1=art is not wrong either.

Wish I could get to Wales these days!

Yeah, I'd agree it's a marginal call, but it appears to be in the address for the Station Master's House which is unlikely for a locality.

I moved the node closer to where OSGB have it (I.e. near the pub & station). I'd have thought 100 years or so there would have been a population in tens (pub, farm with workers, railway, quarry, lime kilns etc.).

This is a well-known place-name relative to others such as Batty Moss or Gauber Limekiln Pasture. The other place I associate it with is the T-junction

Why do you think way/1255759628 is allotments? It would be a very strange location & looks nothing like allotments on aerial imagery.

This, and numerous other polygons mapped hereabouts is a barrier=hedge not landuse=forest. If you don't know what a wooded area is please use natural=wood: apart from Newborough Warren most woodland on Anglesey is deciduous broadleaved semi-natural woodland, not forests.

Thanks,

Thanks for adding the prayer rooms.

Do you know if they are used separately by men & women? I know I've heard male voices from the room on the S on Fridays. Also I think there are other rooms as part of the multifaith centre which also need to be mapped.

I suspect some of the tags on public footpaths should be permissive and not yes (it is a right which can be withdrawn by the NT not one granted by law). I'm a bit out-of-the loop with what the current standards are for NT.

Years ago when Curly Carver was warden there were some issues about which paths horses could use (Broad Ride in the Thicket was one). I think I did map the broader rides on the part of the common near the cricket ground as bridleways.

Either way being explicit about whether riders are permitted or not is definitely a good thing in an area with so many active riders.

I think the summit is better tagged as man_made=survey_point + historic=memorial + memorial=plaque. The actual war memorial is the area donated to the National Trust, which might be quite hard to identify if not in the NT open data. Compare with the WWI memorials to men of Cumberland (Scafell Pike tops) and the members of the Fell & Rock (memorial plaque outlining area on summit of Great Gable). The latter is very we.l documented by the FRCC themselves. Werneth Low Country Park in Hyde is, I believe, similar, but in that case there is a large obelisk acting as a monument on its own.

Yes, No entry except buses sign. Have updated.

That was probably some variant tagging on use at the time. I suspect it means motor_vehicle=no as well. I will need to check ifbI have a photo

Please do not unsubscribe from this conversation.

If you fail to discuss this all these edits may be reverted. Consider that OSM is nearly 20 years old, and infrastructure like the Channel Tunnel will have received attention over many years to make sure it is compatible with various routing services. It is therefore unlikely that existing tagging was very far wrong.

I'm concerned that your changes will break numerous downstream applications which rely on OSM data for routing. This is why such changes need to be discussed.

Yes, well caught : site_tree_no, sitename & tree_type should not be there. The ncc_tree_code is not necessarily a "ref" in OSM terms (it is not the same as the markers on the trees) and is there to allow checks for new trees etc.
