Please turn AI road detection into a QA tool to check for non-existent roads and to detect geometry changes and problems to existing roads.


not even one discussed issue was fixed by the participants of the training

Systematische Sabotage - komplette Siedlungen/Straßen mit Entfernung der Hausadresseinträge

du kannst hier jedes Gebäude aus deinem Änderungsatz aufrufen und die Historie abfragen. Soweit ich das erkennen kann hat es hier keine Löschungen oder schädliche Änderungen gegeben,

Please, stop to devastate Mogadishu

Almost all taller buildings are systematically drawn incorrectly.

This should not happen in organized mapping activities.

Here is my favourite drawn after maxar:

Also interesting these swimming pools

But if there is a willingness to fix such problems, I would not recommend a rollback. There are local mappers involved, so it still can be turned into something useful. HOT promised some time ago not to leave such problems to the OSM community.

Please, stop to devastate Mogadishu

So after the OEGs and according to recent activities, the base map is now in an acceptable state?

AI-assisted workflows - could you please provide a working link

Lot of frustration due to bad H.O.T. tasks

Your custom imagery is of good quality but maxar premium beta is more recent. When looking into the data I wonder why most of the tiles are still green and why there is almost no activity at the moment. Although the road network needs an update, it shouldn’t be messed up by a building only task.
Please fix at least all the building/road intersections.


where can one review the map data that has been created?

Potential HOT tasking manager improvements to help new and existing contributors collaborate more effectively

TM projects don’t always get closed out - this is highly problematic! Especially when a single mapper takes over an entire project that is no longer monitored. See #hotosm-project-5842 (who is responsible when the project manager cannot be reached) or #hotosm-project-1497. #hotosm-project-1045-loreto is also a project that has produced very interesting results over the years

Viel Spaß noch

Deine Mitarbeit wird uns fehlen. Speziell auch in der Region zwischen Lahn und Sieg


edwin-ldbg das warst du oder? Und jetzt schon wieder weg wegen diesen CS-Kommentar Nörgelleien. Finde ich jetzt echt schade,ehrlich.

What Imagery to Use for Validation?

Always the latest layer! Determine it by comparing all available layers. The older layers may offer different lighting, resolution and viewing angle to make things more clear.

Cloudy satellite image

Hi, esri seems to be more recent, and it is cloudless.

OSMF elects all Male, Northern Board

and how many of this local chapters will be controlled by HOT? With all the western male big money influence from organizations like red cross, msf, facebook,apple,uber.. in behind.

Zoomlevel Digitalglobe

Soweit wie möglich rein zoomen. Dann Rechtsclick auf den Bildlayer und Autozoom auschalten.

[Not finished yet]The Dark side of the Crisis/Mass Mapping

Does anyone even check what HOTOSM contributors leave behind?

It is not only a problem of new mappers. This Problem is in deed very HOT specific. HOT is encouraging new mappers, to map places, where nothing is to find comparable to their normal environment. And in some boring tiles, where nothing is to map, even experienced mappers start to map animal traces as highway=unclassified. Project managers and requesting organisations are most of the time neither involved in mapping nor in validating. No critical feedback, only success stories all the time.

The OSM street network is more than 80% complete

Your figures may be right, where a strong local community is present. But in Africa, where most of the content was added during missing map campaigns we have large areas with absolut unusable data.

Review of Africa Highway Tags

Hi, we can discribe any possible road condition with existing tags. When a road is not suitable for normal traffic, it should be tagged as track. You may want to invent a additional tag, like we do with service roads (, but certainly no new road type

Mapping turn lanes in OpensStreetMap

Complex junctions - With a lot of guesswork. If some one has local knowledge, we could adapt this to the reality. But it is generally not too complicated to map such complex junctions with the *.lanes scheme OSM-file
