Which imagery is ‘best’ will depend on where you are in the world. And ‘best’ may change depending on what is wanted - most up to date, best resolution or best alignment. You certainly need to use more that one image, best if you look at all of them for each new area so you can asses them and make your own choice.

If that is what they are doing .. then I too would go to the DWG.

I take it you have contacted them to ask.. and they have responded.. and there is no resolution. If they don’t respond .. then DWG No resolution ..that then should be done through the local OSM community - a majority decision.

Many areas local to me .. and some not so local lack building outlines.. and addresses. I am targeting the CDB of places where tourist go, adding both building outlines and addresses as I think those will be of the most use of my time and best appreciated by many.

The landuse things here have been added from imagery, in some cases roughly, and can benefit from a tidy up when time is avalible. JOSM extra tools has a ‘replace geometry’ function that works quite well in these situations. I draw a new way on a blank layer, merge it onto a layer withe the old landuse way an replace the old with the new. This assumes that the old way is not connected to anything .. like a road… grr. In that case I do simply delete the older landuse (leaving the roads behind of course) and introduce the new landuse. If I’m really at a loss with what to do with my time I take a more kindly approach and separate the old land use for the other ways .. but I’m less likely to do that now as there is much to do in OSM.

Did Donald Trump go there?

Arr found what I was looking for .. has photos .. much better. osm.wiki/East_Africa_Tagging_Guidelines#Roads_in_East_Africa

That might get some of your people thinking. I do like the elephant in the track photo, contrast it with the Tertiary road in Uganda. I think it demonstrates that the road condition is not what necessarily makes the road classification, but rather how the community use it, and that takes local knowledge rather than a simple satellite view.

Careful! There ‘open data’ may not be compatible with OSM legal requirements. I’d not start using the data untill you have confirmation that it is legal to use in OSM. Good Luck.

Passion is good. The problem is when passions conflict.

The problem with ‘track’ is that it has some many different meanings depending on a persons experience. A person that drives a sports car will have a different interpretation compared to someone who drives a 4WD.

And there will be different interpretations between countries. Putting that all together on one world wide map is difficult.

However for your circumstances .. osm.wiki/Canadian_tagging_guidelines is a starting point. But it is not as clear as some osm.wiki/Australian_Tagging_Guidelines#Road_Tagging

Good Luck. I think you have the correct approach ..not all ‘dirt roads’ are ‘tracks’.

Don’t be afraid. Revert it. If you don’t like what the reversion has done .. don’t upload it to OSM. Only when you upload the data does OSM get the reversion, so just try it and see if it does what you want, if not just abandon the reversion.

Take the case of Greenland. While the official language is West Greenlandic (there is Thule, South Greenlandic and East Greenlandic too) all schools teach English and Danish too. I would think the probably increase in OSM participation rates by providing a West Greenlandic translation would be close to 0.

Then you have ‘Western Shara’. That is disputed territory to put it mildly. Maps showing that were (could still be) baned in Morocco … I’d not travel therewith such a map.

Then Mongolia, where navigation is by yurt, not GPS. Most people, out of town, travel from one yurt to another, yurts move! They move to keep the herds at good feed, people travel from one yurt to another to keep in contact and to aid there own navigation. The navigation by yurts would be frowned on by OSMers, yet that is what is done by the locals.

Targeting a translation simply based on the population numbers or area on a map is not a good idea. It can be used as an input but more considerations need to be made.

While this it true in terms of the numbers of people, it may not be true for the surface area of the world. Which remaining language would give OSM the best surface coverage rather than the population coverage? And which area of the world, that lacks the native language, has the ‘worst’ OSM data (if that can be reasonable quantified)? Does that area have the technical infrastructure to support effective participation in OSM?

While getting more people able to participate is a worthy goal, most people don’t participate in OSM. Targeting those who would and can participate is a better use of resources? Might be good to look at the participation rates of people in Korea, has it risen since the introduction of the new language? Will that participation remain, or is it a simple peak that dies away?

Hi, I have moved some old railway lines and stations over to OHM Open historical Map - this way the data is preserved. I have then removed those bits that don not exist anymore from OSM. For completeness you can leave a changset comment for the mapper to see what has been done.

The adjustment is done on your local PC .. not on the remote image.

You will find that the adjustment may have to be remade frequently as the image may have ‘lumps’ in it (small hill slopes can throw the image off one way on one side and the reverse on the other).

While Hydrogen is ‘easy to ignite’ in the lab (explosive range is something like 6% to 96% .. that is very wide!) .. not so easy within an air balloon. Considerable effort was made to get the bullets to ignite the zeppelins.

Hydrogen is being used as an experimental car fuel … don’t hit one of these! A crash could lead to a loud boom …

There need to be clear policies. A) Immigration B) Religion C) Beer D) Tourism

These could be linked e.g An new immigrant is required to bring/buy beer for 100 local residents (0.5 l each).

Wish more people would ‘virtually visit’ and adding anything they can see to OSM before physically visiting places. This aids their trip, helps them add things while they are there too.

“There be Dragons” :)

Your not alone, many people work at getting a good map. Removing idiocies is one thing .. but there are far more simple errors.

Hi, There is a render that publishes an ‘error’ file for each country/region… I have used that from time to time to see how things are. I have used it from time to time to do any corrections I can.

But a world view of significant changes is nice.

After a number of changset comments to one mapper … and no response .. I tend to get very terse from there on!

Pitty it is not named ‘Street Town’

In Tasmania there is Doo Town osm.org/#map=17/-43.03839/147.94237 Unfortunately the houses and their names are not mapped .. house names such as

Doo Us She’ll Doo Doo Little

https://tasmanpeninsula.com.au/wp/places/eaglehawk-neck-1/see-1/doo-town/

Hmm I might just go and map the houses…done, someone els will have to map the names.

If your going to name those who have ‘ruined data in OSM Jakarta’ then Ficky has add buildings that are not there!

I do think that naming them is abusive, they should be contacted through OSM and asked about their edits. They may have made human errors, errors that they may fix themselves if informed and encouraged rather than held up in a public way as people who ‘ruin’ things.

How someone else uses JOSM is pure speculation … you need to ASK them!

In JOSM you can select, using the Imagery menu, the background imagery of ‘OpenStreetMap Carto (Standard)’ and that will display all the roads and buildings as well as most other things. You can have more than one imagery in JOSM and select from one to the other, even arrange for one to be transparent so you can see your data, one image with another image visible through all that.
