Billboards, information signs and guideposts in Uganda
Proposal status: Draft (under way)
Proposed by: Bert Araali
Tagging: information=*
Applies to: node way
Definition: An extended and advanced scheme to tag all kind of information signs, including billboards and guideposts in Uganda
Statistics:

Draft started: 2017-07-05

On this page, Billboards, information signs and guideposts in Uganda we'll try to make a list of Ugandan signs typically found along official roads, tracks, paths and hiking/cycling routes.

This page is under construction, signs can be added as required in mapping projects. It is intended to help those mappers in Uganda that are new to the project, or those more experienced but looking for a common way to tag signs in the country.

Please note: This is intended as a guide based on what contributors to the page think is best. There may be other equally acceptable alternatives - if so add them to this page with an "or" separator, or discuss first on the discussion page.

Please also note: Some of the tags here may not appear in Map Features and are suggestions instead to cover a requirement. As a result some validator tools may highlight them as errors to be checked.

Terminology

We distinguish, describe and give guidelines on how to map them properly on the following types:

Billboards: for advertising. Might be private or public.
Information: to indicate the name of roads, educational or information signs along roads and on buildings etc...
Guideposts: to indicate the directions to different destinations or names of places or routes.

How to map

Generally, the keys used and their possible values are:

Tag or key Type Requirements Values in Uganda with description
advertising=* Identification Mandatory advertising=board: Is the standard tag on OSM to identify a board (small scale advertisements).

advertising=billboard: Is the standard tag on OSM to identify a billboard (large scale advertisements).
advertising=tarp: Is the standard tag on OSM to identify a tarp.
advertising=flag: Is the standard tag on OSM to identify a billboard in the form of a flag.

man_made=* Identification Optional man_made=advertising: Should be added additionally to the mandatory advertising=billboard tag to support all kinds of rendering and to identify it specifically as a man made structure.
support=* Technical details Optional support=post: The billboard is supported by one or more posts.

support=pole: The billboard is supported by one or more poles.
support=trunk: The billboard is supported by a unique trunk (analogy with the trunk of a natural tree, this type of device is also called an "advertising tree").
support=mast: The billboard is supported by a mast.
support=wall: The billboard is supported by a freestanding wall or a wall of a building. Also applicable for billboards on shelters, kiosk or toilets as these are separately drawn as buildings. We prefer not to use the key support=street_furniture:* in these cases.
support=wall_mounted: The billboard is mounted on a wall. Also applicable for billboards on shelters, kiosk or toilets as these are separately drawn as buildings. We prefer not to use the key support=street_furniture:* in these cases.
support=fence: The billboard is supported by a fence.
support=scaffold: The billboard is supported by a scaffold.
support=ceiling: The billboard is hanged on a ceiling.
support=ground: The billboard is directly put on the ground.
support=pedestal: The billboard is supported by a pedestal.
support=billboard: The billboard is supported by or is a part of another billboard. You should split the billboard into sections (only applicable if drawn on the map as a way way) in case different parts have different technical characteristics, f.i. a part is fixed and another part has winding posters.
support=street_furniture:information: The billboard is part of an information street furniture, billboard, or poster box for example.
support=street_furniture:map: The billboard is part of a map board.
support=street_furniture:bench: The billboard is part of a bench.
support=street_furniture:bin: The billboard is part of a trash bin.
support=street_furniture:recycling: The billboard is part of a recycling container or disposal.
support=street_furniture:clock: The billboard is part of a clock.

    • size=* : the dimensions of the billboard itself (omitting its support)
    • height=* : the height of the billboard (including its support)
    • lit=* : is the billboard lit ?
    • luminous=* : is the billboard luminous ?
    • animated=* : is the billboard animated ? By which method ?
    • sides=* : how many sides does the billboard have (generally 1 or 2)
  • Management
    • operator=* : the company operating the billboard
    • ref=* : the billboard reference
    • access=* : can everybody change the content of the billboard ?
    • land_property=* : who is the owner of the land under the billboard ?
  • Content and visibility
    • message=* : the kind of content shown on the billboard
    • display_surface=* : the surface dedicated to the display of message (without the frame)
    • orientation=* : how is the billboard directed compared to people/traffic flow
    • direction=* : how is the billboard directed (using cardinal points)
    • visibility=* : how far is the billboard visible ?
Sign type Image Rendering on OSM / Mapnik Possible or proposed rendering Description Tags
Public billboard - trunked Kampala (464043292).jpg not rendered Billboard trunk.svg

Major public billboards located typically along major roads. The advertising content can change often as it is sold or leased by authorities or officially contracted companies to advertisers on a limited time base. It is a grounded advertising billboard, supported by a single trunk (analogy with the trunk of a natural tree, this type of device is also called an "advertising tree"), some lit by transmission, and/or animated with winding posters, multiple sides, installed on public domain along (busy) public roads. Very common type of advertising device.

They can be represented on a map either by a single node (at the center or located at the support post) or by a way. So the tagging might apply to a node or to a way.
In the case you draw it as a way the location of the trunk or support can be drawn as a node on the way at the location where the trunk or support is located.

node way Add tagging as described on the wiki page Tag:advertising=billboard. In Uganda we distinguish the Public billboards from the Private billboards by always adding the tag land_property=public for this type.
The key message=* gives an indication on the type of message of an advertising device. It is NOT the message itself (refer to Key:message). Since the message can change often we DO NOT store it, meaning that the key name=* is NOT USED.

Public billboard - wall Uganda-Public billboard-wall.png not rendered Billboard wall.svg

Major public billboards located typically along major roads. The advertising content can change often as it is sold or leased by authorities or officially contracted companies to advertisers on a limited time base. It is supported by a wall, or installed as a free standing wall by itself, some lit by transmission, and/or animated with winding posters, one side, installed on public domain along (busy) public roads or mounted on walls of public or private buildings. Very common type of advertising device.

They can be represented on a map by a way.
