|A marca de construção pode ser usado para qualquer estrada ou via férrea em construção.|
|Usado nestes elementos|
|Situação: não definido|
Principais estradas e sistemas de construção ferroviária tipicamente ter bem mais de um ano para ser concluído. Podemos, portanto, queremos mostrar os regimes em construção no mapa. Muitas empresas de mapeamento comercial também mostram estradas em construção e planeadas estradas.
Usage - general notes
For building sites, the tag landuse=construction should be used instead. Another option is to set the tag construction=yes. This allows to use "construction" much more universal for any kind of main keys without need to change the main key.
Additionally construction=minor can be used for existing highways which will be modified or repaired without being closed. In this case we don't set highway=construction but leave it at its default value.
Example-values for highways under construction
construction=yes will render on Osmarender (currently not in Mapnik) without changing its main tag;
highway=construction will render on Osmarender at zoom levels 14 (Mapnik at zoom level 12) and above if used in conjunction with any of the following;
|motorway||Motorway under construction|
|motorway_link||Motorway sliproad under construction|
|trunk||Important non-motorway road under construction|
|trunk_link||Sliproad to an important non-motorway road under construction|
|primary||Primary road under construction|
|primary_link||Sliproad to a primary road under construction|
|secondary||Secondary road under construction|
|tertiary||Tertiary road under construction|
|unclassified||Unclassified road under construction (alternatively tag <construction=minor>)|
|residential||Residential road under construction|
|pedestrian||Pedestrianised road under construction|
|service||Service road under construction|
|unsurfaced||Unsurfaced road under construction|
|track||Track under construction|
|byway||Byway under construction|
|bridleway||Bridleway under construction|
|cycleway||Cycleway under construction|
|footway||Foot path under construction (alternative tag <construction=footpath>)|
|steps||Steps under construction|
In all cases, the tag will render as a dashed version of the corresponding <highway=.....> tag. See the highway tag for a full description of the rendering style.
Example-values for railways under construction
|rail||Standard gauge railway under construction|
|narrow_gauge||Narrow gauge railway under construction|
|light_rail||Light-railway under construction|
|tram||Tramway under construction|
|preserved||Preserved railway under construction e.g. for steam trains|
|subway||Subway under construction|
|monorail||Monorail under construction|
In all cases, the tag will render as a dashed version of the corresponding <railway=.....> tag. See the railway=* tag for a full description of the rendering style.
It might be tough to get detailed GPS tracks of roads which have not yet opened to the public, but it'll usually be possible to gather a few points along the route, and the route probably doesn't need to be massively detailed. We might miss several schemes - but then again - so do most commerical mapping organisations.
- a further tag could be added to illustrate the expected opening date.
e.g. <tag k="opening_date" v="YYYY-MM-DD"/>
- No text is currently rendered on Osmarender, but this may be fixed later.
