(QA tool)

From OpenStreetMap Wiki
Jump to navigation Jump to search currently displays four global quality assurance layers.

The main difference to previous implementations and to other tools is that the layers are generated directly from a rendering database updated minutely, in other words the data displayed will short term reflect edits.

Warstwa "noaddress"

Warstwa noaddress oznacza kolorowo obrysy budynków które nie mają tagów: addr:housenumber, addr:housename lub addr:conscriptionnumber tagged oraz nie mają wewnątrz obrysu bydynku bądź na jego obrysie tego typu tagu jako punktu. Ponadto renderowane są linie typu addr:interpolationktóre przecinają budynki.

budynki otagowane jako building=<yes, house, residential, apartments, supermarket, terrace, detached, university, school, retail, warehouse, commercial, farm, public, industrial, office, shop, dormitory, train_station, factory, kindergarten, hotel, civic, manufacture> są renderowane na czerwono jeśli brak adresu. Wszystkie inne budynki są renderowane na pomarańczowo.

The check for a node in or on the building outline is computationally rather expensive leading to the layer not being as fast as the noname one. Zoom 0-12 are regularly re-rendered in batch mode.

Naturally in some areas it is common to not have building specific address information, we are currently missing tagging to suppress such false positives. I'm planning on adding support for some further addr tags that are not so common. If you have any suggestions please leave a comment.

Update 25th March 2015

Use a positive list for buildings that likely should have an address instead of the other way around.

Update 23rd March 2013

landuse residential areas that do not contain addresses are highlighted. Currently this is an all or nothing test, I may add a test for address density in the future.

Warstwa "noname"

A zoomed out world overview of NoName roads

Warstwa NoName map layer pokayuje drogi nie posiadajce tagu name=*. It differs a bit from previous attempts in that it respects noname=* and unsigned=* tags (that have never become popular) and is generated directly from a synchronized database. Na chwilę obecną zmiany są renderowane co 5 minut.


czerwony kolor
drogi typu major i minor, oraz service z tagiem service=alley nie posiadające tagu name lub ref
pomarańczowy kolor
drogi typu: service, roundabout bez nazwy, motorway_link, trunk_link
przerywana czerwona linia
przerywana pomarańczowa linia
unsigned=yes oraz / lub noname=yes

Update 28th October 2012

  • render motorway_link and trunk_link in orange. There is currently no clear way to tag such roads in the absence of explicit sign posting.
  • reduce line widths at lower zooms

Update 16th November 2012

Update 26th November 2012

  • support name:left and name:right as valid name tags

has address layer

Displays building and nodes with address information. It uses a similar logic as the noaddress layer however will highlight both a building outline and a address node if such is used on or in the building outline.


"access equals yes considered harmful"

The overlay displays streets (residential to motorway, currently ignores *_link) that have access=yes set. While this is not directly an error, it is an indicator for nonsensical access tagging and has undefined semantics, leading to stuff like adding motor_boat=no to streets in a medievil town. It can always be replaced by something simpler and more correct. The tag is most of the time added by JOSM users using the "Road Restriction" preset form.

See OSM_tags_for_routing/Access-Restrictions and Key:access

The layer further highlights the combination access=destination with motorcar=no which is nearly always an error (it allows everything to locations on the street except cars). The correct tagging would typically be a simple motorcar=destination (often in combination with motorcycle=destination). (QA tool)
