36753287 by Bert Araali @ 2016-01-23 07:06 ~ 10 years ago	1	~ 1 month ago	Jonáš Hubáček ♦6	Can I ask why did you add so many single trees in the map?
114865593 by Bert Araali @ 2021-12-13 04:09 ~ 4 years ago	1	~ 1 year ago	Johnwhelan ♦89	Could you please revisit this object and tag a few untagged ways please. Also it comes up with building within a building. Thanks John
	2	~ 6 months ago	KingVik ♦22	Dear Bert Araali, can you Kindly revisit this and give it a proper tagging, I think this field or local knowledge, one without the knowledge won't be able to fix this
95250078 by Bert Araali @ 2020-12-03 21:35 ~ 5 years ago	1	~ 3 years ago	Tjuro_QA ♦43	Hello Bert Araali, I seems that you have added an man_made=flowerbed: https://www.osm.org/way/880782306 I recently started documenting and using landcover=flowerbed as an alternative to the controversial landuse=flowerbed. https://wiki.osm.org/wiki/Tag:landcover=flowerbed Would y...

	2	~ 4 years ago	Bert 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. Greetings and happy new year, Bert Araali
107336113 by Bert Araali @ 2021-07-03 01:31 ~ 4 years ago	1	~ 4 years ago	habi ♦2,069	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
	2	~ 4 years ago	Bert 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.
	3	~ 4 years ago	habi ♦2,069	No worries, I just wanted to know the reason :)
106257349 by Bert Araali @ 2021-06-12 15:36 ~ 4 years ago	1	~ 4 years ago	mueschel ♦7,026	Please don't add points for alignment of aerial images to the OSM database. There is a dedicated service for that: https://wiki.openstreetmap.org/wiki/Imagery_Offset_Database
	2	~ 4 years ago	Bert 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. A proposal will be established when it gains support. Although the Imagery_Offset_Database is a nice implementation it has the following issues: 1. Data is stor...
	3	~ 4 years ago	mueschel ♦7,026	"Storing it in OSM is even more desirable as it stores real ground truth and verifiable information" 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...
	4	~ 4 years ago	Bert 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...
	5	~ 4 years ago	Bert 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.
105784517 by Bert Araali @ 2021-06-03 14:22 ~ 4 years ago	1	~ 4 years ago	habi ♦2,069	Ciao Bert I corrected your typo 'raze:building' to 'razed:building' in changeset https://www.openstreetmap.org/changeset/105833136 Have a good day, Greetings from Switzerland, habi
	2	~ 4 years ago	Bert Araali	Thank you Habi, much appreciated ! Will search for the same typo in other changesets I made recently. Greetings, from Uganda
	3	~ 4 years ago	habi ♦2,069	I think I caught them all, since I came via http://osm.mueschelsoft.de/taginfo/newkeys.htm and the prepared Overpass turbo query from there...
104005044 by Bert Araali @ 2021-05-02 17:14 ~ 4 years ago	1	~ 4 years ago	Jean-Marc Liotier ♦337	"Calibration point" - you mean a surveyed geodetic control datum marker ?
	2	~ 4 years ago	Bert 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...
	3	~ 4 years ago	Jean-Marc Liotier ♦337	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.
	4	~ 4 years ago	Bert 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...
	5	~ 4 years ago	Bert 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...
	6	~ 4 years ago	Jean-Marc Liotier ♦337	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 ...
	7	~ 4 years ago	Jean-Marc Liotier ♦337	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 ...
	8	~ 4 years ago	Bert 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, ...
	9	~ 4 years ago	Bert Araali	Deletions however are not OK, we defintely disagree on that basis. Not out of respect to the previous editor, neither by the global OSM community. Actually we don't care how outdated the info might be, it's what local communities are able to access, hat was done in previous projects and ...
96925607 by Bert Araali @ 2021-01-04 17:41 ~ 5 years ago	1	~ 5 years ago	ivanbranco ♦2,868	Hi Bert Araali, I think there's a problem with the tag name=* in this way https://www.openstreetmap.org/way/167658128/
	2	~ 5 years ago	Bert Araali	True, copy paste mistake. Corrected it. Thanks for the help.
59463421 by Bert Araali @ 2018-06-01 14:33 ~ 7 years ago	1	~ 6 years ago	SomeoneElse ♦13,722	Just checking - is https://www.openstreetmap.org/relation/8114848 really landuse=residential in its entirety? It seems over large for a refugee camp. For comparison I seem to remember the DRC-conflict camp to the west of Harare being described as "the largest in the world" at the time (l...
	2	~ 6 years ago	Bert Araali	Hello Andy, it mainly is. The landuse=residential tag is added consistent with refugee camp tagging used elsewhere in Uganda and International. It came out of a long discussion and the lack of a specific landuse tag for refugee camps. The relation shows the border and land assigned by the governm...
59089949 by Bert Araali @ 2018-05-18 20:11 ~ 7 years ago	1	~ 7 years ago	mueschel ♦7,026	Hi, you added the key "maxspeed:agriculture" on several ways - the correct spelling would be "maxspeed:agricultural". Could you have a look and fix it? Cheers, Jan
	2	~ 7 years ago	Bert Araali	Hello Jan, Sorry for the typo. I think all of them are fixed now.
	3	~ 7 years ago	GerdP ♦2,825	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
	4	~ 7 years ago	Bert 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...
	5	~ 7 years ago	GerdP ♦2,825	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?
	6	~ 7 years ago	mueschel ♦7,026	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 ...
	7	~ 7 years ago	GerdP ♦2,825	Ah, yes, it is OK to use junction=roundabout on a node for small roundabouts which are not mini-roundabouts.
	8	~ 7 years ago	Bert 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...
	9	~ 7 years ago	mueschel ♦7,026	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
	10	~ 7 years ago	Bert 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...
	11	~ 7 years ago	mueschel ♦7,026	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...
	12	~ 7 years ago	GerdP ♦2,825	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...
	13	~ 7 years ago	Bert 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...
59874087 by Bert Araali @ 2018-06-15 13:07 ~ 7 years ago	1	~ 7 years ago	user_5359 ♦20,548	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.
60435250 by Bert Araali @ 2018-07-05 12:13 ~ 7 years ago	1	~ 7 years ago	mueschel ♦7,026	Hi, you added the tag "buiulding:part" on 74 ways, could you fix the spelling of "building"? Thanks, Jan
	2	~ 7 years ago	Bert Araali	Hi Jan, sorry for the mistake. Typo, will correct them imediatly. Could you help me in detecting those typo's ? I am using ID and JOSM but neither warns me about typo's when editing or uploading. What tool do you use ?
	3	~ 7 years ago	mueschel ♦7,026	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
	4	~ 7 years ago	Bert Araali	Thanks Jan, could help. Would be great if someone just adds some warnings to the validation rules for new tags added. Typos are corrected.
58392445 by Bert Araali @ 2018-04-24 23:52 ~ 7 years ago	1	~ 7 years ago	mueschel ♦7,026	Hi, there are a few spelling mistakes of tags here - it's "height", not "heigth". The same for building:height and roof:height. It's "building", not "buildiing" or "builidng" or "biulding" etc. On the first glance it's ab...
	2	~ 7 years ago	Bert Araali	Hello Jan, also noticed it. I am using ID and trying out some new 3D and indoor tagging features. I am updating it the coming few days and will remove the typos. Thanks for the help.
34848063 by Bert Araali @ 2015-10-24 19:58 ~ 10 years ago	1	~ 10 years ago	Jotam ♦18	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!
