New road style for the Default map style - highway=path is evil about 1 year ago

There is one sensible way of dealing with highway=path, and that's to use Lua processing (available in osm2pgsql as well as other tools such as OSRM and tilemaker)

I wouldn't rule out dealing with it in SQL. It might even be sane, compared to doing z_order in SQL and some of the other constructs.

Osm2pgsql 0.87.4 release about 1 year ago

Just to note, this message was a couple weeks late in getting up.

San Francisco data imports, anyone? about 1 year ago

City and County would like to leverage OSM excellence, yet OSM licensing restrictions make it not feasible for us to use these OSM shapes as our own public reference set

Just to clarify, it is city and county licensing policy and would likely impact any foreseeable license.

New road style for the Default map style - the first version about 1 year ago

Is switching from blue motorways necessary? I realize that blue doesn't cleanly fit into a yellow orange red scheme, but it's unfortunate to lose a color which currently doesn't conflict.

It might be worth looking at http://colorbrewer2.org/?type=sequential&scheme=YlOrRd&n=5 and other options, though blue fits more naturally at the end of a YlOrBr scheme.

San Francisco data imports, anyone? about 1 year ago

California needs a lot of import attention. But the attention it needs is not more imports, it's cleanup of existing imports, particularly landuse imports.

Post scriptum to "long time - no edit" about 1 year ago

Having looked at other projects, our conversion and retention rates are reasonable. That doesn't mean we shouldn't strive to improve it, after all, many of the accounts belong to people who have shown some interest in OSM, but it's a fact of life that people sign up for online accounts then disappear.

Is it the moment for OpenStreetMap? about 1 year ago

Mateusz, it is now. With the new CT, everyone agrees to further relicensing without individual agreements.

Yes - and no. It depends on the license. In the case of a switch to public domain, I estimated at one point that >20% of data would need to be removed - basically most non-US imports. There are additional complications with PD, but they're not worth going into since the chances of a license change removing ~10x the data that was removed in the original license change are approximately zero.

In the case of a switch to an attribution license or different share-alike license, it depends what license. There are many attribution licenses used by third-party sources, and I expect some of them are incompatible with licenses we might consider moving to.

Thirdly, third-party ODbL-licensed data can be imported or used as an external source. This data would need to be removed with any change to the license.

What the CTs mean is that everyone has agreed to a license change process for their contributions.

Nepal, OSM License, and the NGA about 1 year ago

if they're modifying OSM data, rendering in into a produced work (e.g. a map) and publicly distributing produced work they have to make the modified database available*. Looking at the NGA atlases they appear to be layering OSM data with other data, not modifying OSM data. There are some minor attribution problems where they've mangled the OpenStreetMap name slightly and haven't provided license information or a link to it.

The same is probably the case with the Sochi maps, but I'm less sure without comparing geometries.

Using ODbL data within a company or government and not releasing anything publicly is allowed by the license. The share-alike obligations only come into play if something is released publicly.

Any update on the source for the initial edit from Andgol? It obviously wasn't the link given, since that spells it differently.

February release delayed over 1 year ago

It would also help if you were a user of Oracle's list of Root Certificate Authorities if you ask them when they intend to join and use the CA/Browser forum - the industry association for CAs and users, or use the Mozilla ca-certificates component, used by multiple vendors.

New Telenav Mapping Project: Dual Carriageways over 1 year ago

In OSM however, they are often mapped like this

Surely you mean in the unedited US? ;)

Voting is bullshit over 1 year ago

With the exception of a few foundation-related matters (board elections, some WGs, etc) we don't use voting in OSM. You don't need the authority of a vote to tag a way, and there's no requirement to follow what has been voted on.

The part of proposing a new tag that has value is explaining it to others.

Radios Censales De Argentina over 1 year ago

I'm not sure how this connects to OSM. All you've given is some screenshots of data without any text. Is this data in OSM?

The diversity-talk list over 1 year ago

Any idea how many subscribers there are to diversity-talk? It seems that only about 20-30 people are writing there, but is the circle that small, or are there many silent readers?

Although the list has always been mainly white anglo-americans, the recent moderator actions have caused some members to leave in disgust. This has left a list less diverse than others, an ironic state for a list named diversity-talk@

And I wonder if the list can really come out of that without simply dissapearing and reappearing in an other form…

We don't normally shut down lists, but given that the list was already quiet for months on end, the latest subscriber loss is going to destroy any relevance it had left.

It is disappointing, but I guess it's unlikely to have an impact. It's not as if the list was able to impose anything on other mappers outside of the list, and as I said above, it has no activity for months on end.

It will be as before - those who care about diversity will work on it, without regards to the list.

OSM issues apparently ? over 1 year ago

For the ability draw data on top of OSM data you can use umap.

A Proposal to improve the OSMF by Separating Out the Board from Officers over 1 year ago

Minor note, all directors are generally officers of the company, although others may also be officers.

It's largely a terminology matter.

Rendering Oddness for Runway Refs over 1 year ago

/ is the more standard way to indicate runway refs.

The trouble with the ODbL - summarized over 1 year ago

It does not cover hundreds of use of OSM data where the ODbL license is not an issue at all.

Including the data that OSM can use only because it is distributed under the ODbL license!
