WikiProject Uganda/Conventions/Barrier
Status: Draft (under way)
Proposed by: Bert Araali
Tagging: barrier=*
Applies to: node way
Definition: An extended and advanced scheme to tag all kind of barriers typically found in Uganda
Drafted on: 2017-07-07

On this page, WikiProject Uganda/Conventions/Barrier we'll try to make a list of Ugandan barriers typically found on or along official roads, tracks, paths and hiking/cycling routes.
A barrier is a physical structure which blocks or impedes movement. The barrier tag only covers on-the-ground barriers, it does not cover waterway barriers (dams, waterfalls...).

This page is under construction, barriers 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 barriers 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.


Please visit the wiki page Barriers.
We distinguish, describe and give guidelines on how to map them properly on the following types:

Area barriers: this type of barrier is not described as a standard on the wiki. However many occur along the roads and are important features which should always be mapped in Uganda. One of the most important examples are f.i. flowerbeds along roads and at major junctions.
Linear barriers: to indicate the name of roads, educational or information signs along roads and on buildings etc...
Nodular barriers: to indicate the directions to different destinations or names of places or routes.

Public billboard - trunked Kampala (464043292).jpg 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, 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.

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.
