Tagging options for the urban typologies of Ng'ambo, according to the NGT team project field survey.
Use of the key urban:typology=* introducing new, more specific for this context values.
Urban Typology values
These are the options you can put into the key building=*. You must use an option. When you trace you will almost always put in 'yes', but when you are out in the field, you should pick a more specific value.
|building||apartments||A building arranged into individual dwellings, often on separate floors. May also have retail outlets on the ground floor.|
|building||hotel||A building designed with separate rooms available for overnight accommodation. Normally used in conjunction with tourism=hotel for the hotel grounds including recreation areas and parking.|
|building||house||A dwelling unit inhabited by a single household (a family or small group sharing facilities such as a kitchen). Houses forming half of a semi-detached pair, or one of a row of terraced houses, should share at least two nodes with joined neighbours, thereby defining the party wall between the properties.|
|building||residential||A general tag for a building used primarily for residential purposes. Where additional detail is available consider using 'apartments', 'terrace', 'house' or 'detached'.|
|building||commercial||A building where non-specific commercial activities take place; use office=* to describe the type of office. Consider tagging the area using landuse=commercial. Use 'retail' if the building consists primarily of shops.|
|building||industrial||A building where some industrial process takes place. Use warehouse if the purpose is known to be primarily for storage/distribution. Consider using landuse=industrial for the surrounding area and the proposed industrial=* tag to describe the industrial activity.|
|building||retail||A building primarily used for selling goods are sold to the public; use shop=* to identify the sort of goods sold. Consider use landuse=retail for the surrounding area.|
|building||warehouse||A building primarily used for the storage or goods or as part of a distribution system.|
|building||mosque||A mosque. Used in conjunction with amenity=place_of_worship, religion=*, denomination=* and landuse=religious for the grounds where it is in current use.|
|building||civic||For any civic amenity, for example amenity=community_centre, amenity=library, amenity=toilets, leisure=sports_centre, leisure=swimming_pool, amenity=townhall etc. Use amenity=* or leisure=* etc to provide further details. See building=public as well.|
|building||hospital||A building which forms part of a hospital. Use amenity=hospital for the hospital grounds.|
|building||school||For any generic school buildings. Buildings for specific uses (sports halls etc) should be tagged for their purpose. Use amenity=school for the perimeter of the school grounds.|
|building||public||A public building. Don't use amenity=public_building.|
|building||kiosk||Use this for single box Duka's that are not inside a bigger building|
|building||container||When a container is used as a building. If there is a shop in the container use 'retail;container'.||Need a Zanzibar Picture|
|building||ruins||An house, a village or other building abandonned.|
|building||yes||Use this value where it is not possible to determine a more specific value.|
|building||construction||Used for buildings under construction. Use construction=* to hold the value for the completed building.|
Tagging options for the architectural style of Ng'ambo buildings, according to the NGT team project field survey.
Use of the key building:architecture=* introducing new, more specific for this context values.
Architectural Style values
|Key||Value||Description (to be edited)||Photo (to be filled)|
|building:architecture||classic_swahili|| ... (to do: add a chapter in Wikipedia "Swahili Culture" page about "Architecture")
Swahili Architecture? -If we update it yes... we can use that one instead.or
|building:architecture||indian|| and there are many more indian Architecture styles on this page, too.) -hmmmm. we wait for the description first.(RB: I found|
We should mention how this key relates to building=. Especially for mosque or market_stall. Of the quite generic definition in the previous paragraph, how do we encourage people in the OSM community to use this field and what kind of values do we want them to start using? -Maybe we do that in the proposal page?
Tagging options for the architectural typologies of Ng'ambo buildings, according to the NGT team project field survey.
Use of the key building:architecture:typology=* introducing specific for this context values.
The official Proposal for key:building:architecture:typology is currently a sandbox.
Architectural Typology values
|Key||Value||Description (to be edited)||Photo (to be filled)|
|building:architecture:typology||single_storey_swahili||Predominantly residential, single storey, multi-functional.|
|building:architecture:typology||modern_multi_storey_swahili||Predominantly residential, two or more storeys, built on footprint of single-storey Swahili house|
|building:architecture:typology||post_modern_multi_storey_swahili||Contemporary multi-storey buildings built on one- or multiple footprints of an old Swahili house (single_storey_swahili value link here). The post-modern multi-storey Swahili comprises both residential and mixed-use buildings found in the Ng’ambo area. For the time being most of the post-modern multi-storey Swahili buildings are either solitary buildings placed within the context of single-storey Swahili houses or groups of two or more independent buildings built close to each other with little consideration to the neighbouring structure, yet respecting the street line. Post-modern multi-storey Swahili can also be seen as an emerging tendency within the architectural development of the area.|
|building:architecture:typology||suburban_villa||Single family house, surrounded by garden, often fenced.|
|building:architecture:typology||indian_shopfront||Mixed-use, residential and commercial|
|building:architecture:typology||modern_indian_shopfront||Three or more storeys, built on the footprint of an Indian shopfront, mixed-use, residential and commercial.|
|building:architecture:typology||arcade_building|| 1-2 storeys with arcades housing commerce, remaining storeys residential or other use.
Architectural typology mainly found in Dar es Salaam describing multi-storey buildings comprised of shopping arcades on the two first storeys and with more enclosed remaining storeys used for offices, hotels and residential purposes.
|building:architecture:typology||high_street||Multi-storey and mixed-use typically urban phenomenon found in the United Kingdom. It is used as a metonym for the concept of the primary business street of towns or cities especially to distinguish it from more concentrated city centres. As Ng’ambo lacks a clearly defined CBD we have decided to borrow the High Street concept to define streets with high concentration of business developed in recent years.|
|building:architecture:typology||others||Leisure /tourism - sport clubs/clubs/guest houses/hotels etc.|
Tagging options for the building structure , meaning building technologies or main materials of buildings found in Ng'ambo, according to the NGT team project field survey. Use of the key building:structure=* introducing new, more specific for this context values.
The key building:structure is different than the key building:material as building:material describes only the outer layer of the building or roof. It is used by 3D rendering engines. building:structure describes how the building/roof was constructed. eg. a building:structure=cement_blocks may have material=metal or material=plaster depending on what the ultimate finish layer of the building is.
The official Proposal for the key:building:structure is currently a sandbox.
Building Structure values
|building:structure||wattle_and_daub|| Wattle and daub is a composite building material used for making walls, in which a woven lattice of wooden strips called wattle is daubed with a sticky material usually made of some combination of wet soil, clay, sand, animal dung and straw.
|building:structure||concrete_frame_and_cement_blocks|| Building technique in which concrete counteracted with steel reinforcing bars is forming the building’s structural system, while the filling of walls is made of cement blocks.
|building:structure||cement_blocks|| Masonry technique of making mainly one floor buildings with cement blocks and a binding material. Sometimes reinforced with simple concrete rings.
|building:structure||coralstone_and_lime|| Masonry technique of making stone structures from a type of limestone called coralstone, a binding lime mortar and lime plaster.
