Regions and priorities

Zanzibar Architecture

Zanzibar is famous for its unique architecture. OpenStreetMap will capture this unique history using the following tagging guidelines:

(This part of the page is under a lot of editing, this is a very very rough first list of features used:)

First, the basis of mapping architecture can be found on the OSM Buildings page.

Keys that need special attention are:

  • man_made=courtyard proposed tag for courtyards
  • architect=* to indicate the architect of a building
  • building:condition=* for the condition of the building
  • ruins=* - for ruins of buildings
  • abandoned=* - for a building which has been abandoned by its owner and is no longer maintained
  • start_date=* - the year of construction. If the date is unclear, a Date Range can be used.
  • building:architecture=* - According to Wikipedia-16px.png Architectural_style characterizes a building by the features that make it notable and historically identifiable. Could this be extended with 'Zanzibar House'?
  • historic=* - If a building has an historic significance. eg. historic=city_gate
  • historic=* - If a building has an historic significance. eg. historic=city_gate
    • historic=heritage - For official heritage sites this tag can contain the operator = UNESCO and the UNESCO Id


  • ref:whc 1055
  • whc:criteria (ii)(iv)(vi)
  • whc:inscription_date 2001

Additional Tags:

  • website=* - For official websites eg. ministries or companies.
  • wikidata=* - For features that have their own Wikidata page, this allows computers to merge in data (for example pictures) from wikipedia.
  • wikipedia=* - For features that have their own Wikipedia page, this allows sites to clearly link to Wikipedia when relevant.
  • tourism=* - To indicate this building is interesting for tourists.

Stone Town

The old Stone Town area is a UNESCO world heritage.


The Ng'Ambo area is planned to be the new City Centre. In order to support the development of the plan, a good map of the current situation, but also of the way that Ng'Ambo has developed over time is required.

The government of Zanzibar is in the process of creating this map as a basis for a new city plan for Ng'Ambo. (We can add this plan to the list on this page.

Other areas

There is keen interest to enhance the quality of the map in the more rural areas of Zanzibar as well.

Public Transport

In Dar es Salaam a lot of work has been done all the DalaDala routes. The mapping guidelines used there are also applicable on Zanzibar.

NGT Project

The NGT project requires maps of the above. This will require a lot of fieldwork, where some of the tagging is quite specific, so we developed several guidlines:

  1. Zanzibar Building Tagging Guidelines
  2. Zanzibar POI Tagging Guidelines
  3. Zanzibar Typology QGIS Map Guidelines
