Could you please revisit this object and tag a few untagged ways please. Also it comes up with building within a building.

Thanks John

Hello Bert Araali,
I seems that you have added an man_made=flowerbed:

I recently started documenting and using landcover=flowerbed as an alternative to the controversial landuse=flowerbed.

hi, could you please check this way:

22021-12-30 09:25Bert Araali Hi rab, thanks for the tip. Road section is indeed in th meantime finished and open to motorvehicles. I changed the tagging. See changeset https://www.openstreetmap.org/changeset/115554305.

Ciao Bert
In this changeset you introduced the tag `OSM=no` on some buildings: http://overpass-turbo.eu/s/197M
What does this tag mean, since these *are* in OSM? :)
Greetings,
habi

PS: I came here from https://osm.mueschelsoft.de/taginfo/newkeys.htm
22021-07-05 13:35Bert Araali Hi Habi,
I am running some test where I use JOSM as an editor with a seperate layer containing data that shouldn't be uploaded to OSM. The tag OSM=no landed by mistake from this layer on some OSM items. So I deleted it from these items. Sorry for the confusion.

Please don't add points for alignment of aerial images to the OSM database.
There is a dedicated service for that:

22021-06-14 11:48Bert Araali I know, and I am a very intensive user of it. The calibration point keys I am adding at this time are an extension and tested out locally.

No, it doesn't. It's not even clear which version of images from which provider it refers to. Knowing the date and provider doesn't help either, because you could have any...
42021-06-14 15:14Bert Araali They are not offsets, it doesn't refer to any imagery, it is like the calibration points in the Imagery Offset database, coordinates in WGS84 as default in OSM, independent from any imagery or other data but usable to determine offsets accurately. Calibration:lon and calibration:lat refer to th...
52021-06-14 18:37Bert Araali Changed the decimal , to . . Noticed also that mistakenly some buildings were copied with lat and lon on a building, copy error. Deleted those tags. Everything is now according to calibration points also stored in Imagery Offset Database. Will prepare doc later this week.

"Calibration point" - you mean a surveyed geodetic control datum marker ?
22021-05-03 03:37Bert Araali No, I mean a calibrated area stored in the Imagery Offset Database (https://wiki.openstreetmap.org/wiki/Imagery_Offset_Database). The calibration was done with multiple GPS tracks, recorded in the field and Mapillary tracks. I didn't use Strava in this case because we had lots of GPS data. We...

♦335
Geodetic markers would be wonderful to clear imagery confusion. Bing imagery indeed has been a terrible source of offset features. At the moment, both Mapbox and ESRI imageries match GPS traces well, as far as I can tell from the Openstreetmap-recorded GPS traces available as a layer in JOSM.
42021-05-03 12:25Bert Araali Our experience is the contrary, Bing in most cases is more accurate then Maxar or Esri. Especially Maxar is troublesome, with large misalignments and semi-transparant overlaps between tiles, f.i. here, gaps between tiles, and tiles captured at different dates at different zoom levels (f.i. around Mo...
52021-05-03 12:43Bert Araali The tea factory at first glance doesn't seem to be a mistake, on the most recent sattelite imagery it seems demolished, I assume becuase it was build on government land in the wetland. I live only a few kilometers away from it so will go there and check one of the coming days. I got the misal...

Regarding imagery alignment, it seems that, in Kampala (situation of course varies by region - my experience in other countries is different), all current imagery is correctly aligned with GPS traces - see this quick comparison: https://imgur.com/a/xuh7cLw. Mapbox and Maxar are the same capture but ...

Use of Bing explains a lot of the false buildings - https://imgur.com/a/xuh7cLw shows that all others have congruent current imagery but Bing shows buildings long since demolished and doesn't show newly constructed ones. Buildings traced on Bing imagery and since then demolished as attested by ...
82021-05-03 21:50Bert Araali Bing gets updated, but at a much slower pace and recently with images from Digital Globe, some might be identical to the Maxar ones. The comparison on imgur (you made this ?) is just a spot check. Difference between the different imagery sources range up to 20m, I have plenty of examples for that, ...

22019-05-30 12:07Bert Araali Hello Andy, it mainly is. The landuse=residential tag is added consistent with refugee camp tagging used elsewhere in Uganda and International.

Hi!
I've fixed a few more issues at Isingiro Roundabout, see https://www.openstreetmap.org/changeset/63968920
I think you should not use junction=roundabout on a node like here:
https://www.openstreetmap.org/node/5612340183
42018-10-29 08:30Bert Araali Hello Gerd,
Thank you for helping to improve. I'm not really getting your point about the junction=roundabout issue. You say we should not use it on a node ? Or do you mean not use it on the short access roads to the junction ? I know I mostly use two methods because in differences in routin...
52018-10-29 08:42GerdP
♦2,756
My understanding of the wiki
https://wiki.openstreetmap.org/wiki/Tag:junction%3Droundabout
is that the tag junction=roundabout should not be used on nodes at all.
Which routing apps do you mean?
62018-10-29 09:18mueschel
♦6,591
Hi,
you can use the tag "junction=roundabout" on nodes - but only if the "road ring" is not mapped in detail. If the road is mapped, then the junction tag applies to the way, and is not put on the nodes anymore.

Essentially, you're now passing 3 roundabout objects when ...
72018-10-29 09:49GerdP
♦2,756
Ah, yes, it is OK to use junction=roundabout on a node for small roundabouts which are not mini-roundabouts.
82018-10-29 09:52Bert Araali Hi, the routing apps I meant are maps.me (OSRM based) and OsmAnd. I use those to test routes when moving around.
Mueschel's comment explains it clearly but my intention was different. The nodes with the junction=roundabout was tagged to define the location of the traffic signposts. For traff...
92018-10-29 10:05mueschel
♦6,591
Shouldn't the signs be something like
traffic_sign=roundabout ? This tag is not used yet, but follows the generic key for traffic signs. In fact, some are mapped with the local reference number such as
traffic_sign=DE:215
102018-10-29 12:17Bert Araali Very much true. I did the same for Ugandan traffic signs. Using the keys traffic_sign=UG:number. However, if you look in the wiki for the Highway tag you find values like give_way and stop, as the wiki says to indicate the location of a give_way or stop sign. The highway key however doesn't gi...

♦6,591
Consistency was always a weak point in OSM :-) My opinion:
highway = give_way and stop should mark the position of the line / the place where you have to wait. I don't think this is used at all at the side of road. There shouldn't be many more examples of the highway tag used to mark sign...
122018-10-30 07:54GerdP
♦2,756
I agree with mueschel. My understanding is that the routing apps should show something like "enter roundabout ... leave roundabout at 2nd exit". The apps don't need to know where the traffic signs are. I think when you map a traffic sign it shows that you visited the place, thus it so...
132018-11-01 10:38Bert Araali Hello, I did some more research which showed that traffic signs which are not tagged as parts or nodes on a highway are completely ignored. Now they are essential parts in traffic control and in mapping in general. So I think the best solution is to go for a compromise being adding a node at the a...

Hello! Short comment to relation https://www.openstreetmap.org/relation/1110965 : the key "disused:name:1972-1997"means that the name was not used in the period from 1972 to 1997. The correct key is "name:1972-1997" or old_name.

It's difficult to warn about spelling mistakes as there is no constraint on which keys you might use. I'm using a list of new keys that weren't used before based on Taginfo:
http://osm.mueschelsoft.de/taginfo/newkeys.htm
42018-07-06 13:16Bert Araali Thanks Jan, could help. Would be great if someone just adds some warnings to the validation rules for new tags added.

Please DO NOT give the same name to many objects (like "Ministry of Public Service"). Instead, use ONE node with "office=government" and the name. Please correct this. Thank you!
