[OSM-dev] Wiki no longer shows diffs

For the last day or so, the wiki has been showing blank diffs for every 
edit, for example:

http://wiki.osm.org/w/index.php?diff=prev&oldid=1060762

Not sure what happened, but it's making it difficult to track changes on 
my watchlist. Thanks in advance to the sysadmins for looking into the 
matter.

[OSM-dev] OSM based replacement for Natural Earth national boundaries


Most OpenStreetMap maps use the Natural Earth boundary data for showing 
national boundaries at the lowest zoom levels. On

http://www.imagico.de/map/boundaries_download_en.php

you can now find a replacement for that based on OSM data and simplified 
specifically for the common web map zoom levels.  Also the maritime 
boundaries are trimmed to where they are actually useful.

Some more background information is available on

http://blog.imagico.de/rendering-boundaries/

and a simple map showing the data on

http://maps.imagico.de/#map=3/55.0/0.0&r=coastline&o=7&ui=0

[OSM-dev] [meta] Problem with reply to messages from mailing list on Gmail

I have a problem with mailing list - using "reply" is addressing e-mail to just person
that submitted message, not the entire mailing list.

http://webapps.stackexchange.com/questions/37046/making-gmail-to-use-reply-all-automatically-in-mailing-list-replies indicates that there is no easy fix

Surprisingly replying to messages from tagging mailing list are automatically addressed
to mailing list, despite the same addressing scheme.

Is there some known fix for this issue (so reply to e-mail for dev ml will work like
replying to tagging mailing list) beyond "stop using gmail, start using X"?

[OSM-dev] Switch2OSM tile server: socket bind failure

Hello,

I have been trying to build my own tile server following the tutorial
at http://switch2osm.org/serving-tiles/building-a-tile-server-from-packages/
but I have not been successful. Below are some issues I have been
having.

From my research, some forums have suggested to edit a file that
resides at /etc/mapnik-osm-data/inc/, but such a folder does not
exist... (solution according to
http://forum.openstreetmap.org/viewtopic.php?id=19338 suggests to edit
/etc/mapnik-osm-data/inc/datasource-settings.xml.inc).

I do not have a mapnik-osm-data folder under /etc. However, there is a
folder of name `mapnik-osm-carto-data` containing a file `osm.xml` and
a folder called `symbols` containing  various map icon pngs.

When running `renderd` I get
  ```
  socket bind failed for: /var/run/renderd/renderd.sock
  ```

When running `renderd -f` I get the result below.
  ```
  renderd[4477]: Initialising unix server socket on
/var/run/renderd/renderd.sock
  socket bind failed for: /var/run/renderd/renderd.sock
  ```
  Running `sudo renderd -f` gives the correct message
  ```
  renderd[4492]: Initialising unix server socket on
/var/run/renderd/renderd.sock
  Created server socket 4
  ```
  However, I also get a bunch of Bad connection messages as shown below:

  ```
  renderd[11798]: Loading parameterization function for
  renderd[11798]: Loading parameterization function for
  renderd[11798]: An error occurred while loading the map layer

  ```

When I navigate to myserver.org/osm/slippymap.html, the tiles are
pink, and when I navigate to myserver.org/osm/0/0/0.png I get a Not
Found message from the server.

Not sure where to proceed from here. Any help or advice would be much
appreciated. Thanks!

[OSM-dev] Release openstreetmap-carto v2.25.0

Dear all,

Today, v2.25.0 of the openstreetmap-carto stylesheet has been
released and rolled out to the openstreetmap.org servers. It might
take up to 48 hours before all tiles show the new rendering.

Changes include:

* New style for marsh/wetland rendering.
* Added rendering for marsh/wetland and mud labels.
* Changed rendering of national parks boundaries.
* Changed rendering of theme park boundaries.
* Country and state labels are now only rendered for areas of a minimum size.
* Airport icons are now also rendered on zoom 11, 12 and 13.
* Various bug fixes.

For a full list of commits, see
https://github.com/gravitystorm/openstreetmap-carto/compare/v2.24.0...v2.25.0.

As always, we welcome any bug reports at
https://github.com/gravitystorm/openstreetmap-carto/issues.

[OSM-dev] Chinese spam diaries, an analysis

A spammer is periodically posting messages in Chinese to the User Diaries.
These diaries follow a distinct pattern:

1. Reading machine translations, the messages advertise a variety of
products and services that are against the law. This may be to attract
people who would be reluctant to contact the authorities and admit what they
are looking for.

2. Diaries are posted in batches of considerable size (up to 20+), typically
differing only in having different names of cities and provinces in the
text. This would appear to be targeted at searches through search engines.

3. Diaries rarely contain links (occasional exceptions) so cannot be
targeted at search engine rankings for pages hosted away from OSM.

4. Numbers preceded with the letters QQ appear regularly; these may be
accounts with the Tencent QQ messaging service.

5. The spammer has come back repeatedly creating new accounts so it is
likely that that the operation is successful.

I have not followed any message account, keyword or link in any of the
spams. Among other issues I am wary about possible malware in scam pages.

[OSM-dev] Automated tracing (expanding scanaerial)

Has anybody attempted to expand scanaerial to include support for other data sources?
For example vastly more detailed sources like Bing?

Is there some reason that makes it hard/impossible/illegal or is it just "nobody had
time to do it"?

Scanaerial is impressive, but due to extremely low resolution of Landsat it is useful only
for mapping Siberia and other remote regions where big water areas are still not mapped.

[OSM-dev] Is there some loop trip founder?

There is some software, better or worse that is able to find routes from point A to point B.

But is there any tool capable of finding interesting trips starting in some selected place,
that returns to the point of origin after going through some interesting* places using good*
ways?

* - obviously it should be definable - such general tool may be capable of proposing route for
cycling trip, trekking on foot or for a demonstration.

[OSM-dev] Shared borders of (multi) polygons represented as duplicated ways

Hi!

While preparing a dataset for a community import (https://wiki.openstreetmap.org/wiki/Slovenia_Landcover_Import_-_RABA-KGZ ) we ran into 2 kinds of related problems that originate from Shapefile's different representation of polygons:

a) duplicated ways: when no tags are present on two overlaping ways, but ways are members of different relations JOSM reports this as an error. This is common mostly with nested multipolygon relations, where one relation's outer way is the other's inner member.

b) Ways on same position: this is similar to previous, but some tags differ, making the match not exact. JOSM reports this as warning. This is more common, because it doesn't require that many levels of nesting, A simple meadow in a multipolygon forest is enough.

The illustraded description is in the issue of ogr2osm (my first choice for preparing the dataset):
https://github.com/pnorman/ogr2osm/issues/28 (not fixed yet).

Vincent promptly fixed the JOSM's OpenData plugin for importing shapefiles and adjusted validation logic: https://josm.openstreetmap.de/ticket/10743 , so we might go this way (shp -> JOSM instead of ogr2osm -> JOSM or any other editor), but it will require adjusting the data preparation scripts, and more importantly, relying on the end users (community importers) for using the latest (development) builds of JOSM with latest OpenData plugin to fix the data during the import.

While editing existing OSM data I noticed that this is quite common problem in OSM database, even if not coming in via imports (manual edits).

My questions are:
Are duplicated ways considered erronous and to be avoided at all costs or are they tolerable?
Are any tools (osm inspector and similar) detecting these problems?
Are there any plans to fix such topological errors (if considered as such) in existing data by bots (automated edits)?
Is ogr2osm being used for other imports with similar problems? 
Is ogr2osm being actively maintained?

thanks,
Stefan
