Potential HOT tasking manager improvements to help new and existing contributors collaborate more effectively 9 months ago

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 about 1 year ago

What Imagery to Use for Validation? over 1 year ago

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.

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

OSMF elects all Male, Northern Board almost 2 years ago

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.

Does anyone even check what HOTOSM contributors leave behind? about 4 years ago

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 about 4 years ago

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. http://www.openstreetmap.org/#map=17/-1.83031/34.11777 https://www.openstreetmap.org/#map=17/-15.95590/35.08909 http://www.openstreetmap.org/#map=16/-18.3283/21.8104

Review of Africa Highway Tags over 4 years ago

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 (http://wiki.openstreetmap.org/wiki/Key:service), but certainly no new road type

Mapping turn lanes in OpensStreetMap about 6 years ago

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

Mapping turn lanes in OpensStreetMap about 6 years ago

In some rare cases you might need to use relations. Please check this proposal, where some strange cases were highlighted. http://wiki.openstreetmap.org/wiki/Proposed_features/lanes_General_Extension/ProposalPreVoting#Lane_connectivity Here is an example of a simple crossing which incorporates 15 turnlanes:turn relations: https://www.openstreetmap.org/node/199483223 The problem with that is not the tagging but the maintenance.

Mapping turn lanes in OpensStreetMap about 6 years ago

When looking at this segment, one will understand that there are reasons for the wider usage of the *:lanes scheme. First: It is human readable. Second: It is simply extendable with common tags and therefore it it much more versatile as this aged zombie proposal. And by the way, simply counting relations and ways is like trying to compare of apples with oranges http://www.openstreetmap.org/way/361770445

Mapping turn lanes in OpensStreetMap about 6 years ago

As mentioned before, there is already an approved way to map turnlanes in osm. http://wiki.openstreetmap.org/wiki/Key:turn:lanes This scheme is also supported by osmand and mapfactor since some time.

Hallo 4gruwe,
wäre echt schade einen so aktiven Mapper in direkter Nachbarschaft zu verlieren.
Falls du dich an meinen Edits gestört haben solltest könnten wir das auch vor Ort klären.
