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

A highway=construction tag or railway=construction is necessary for any of the construction values to render.

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.

Values

Values of construction=* can be all values from highway=*, railway=*, waterway=* and landuse=*.

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;

Value Element Comment Example
motorway caminho Motorway under construction  
motorway_link caminho Motorway sliproad under construction  
trunk caminho Important non-motorway road under construction  
trunk_link caminho Sliproad to an important non-motorway road under construction  
primary caminho Primary road under construction  
primary_link caminho Sliproad to a primary road under construction  
secondary caminho Secondary road under construction  
tertiary caminho Tertiary road under construction  
unclassified caminho Unclassified road under construction (alternatively tag <construction=minor>)  
residential caminho Residential road under construction  
pedestrian caminho Pedestrianised road under construction  
service caminho Service road under construction  
unsurfaced caminho Unsurfaced road under construction  
track caminho Track under construction  
byway caminho Byway under construction  
bridleway caminho Bridleway under construction  
cycleway caminho Cycleway under construction  
footway caminho Foot path under construction (alternative tag <construction=footpath>)  
steps caminho 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

railway=construction will render on Osmarender at zoom levels 14 and above if used in conjunction with any of the following;

Value Element Comment Example
rail caminho Standard gauge railway under construction  
narrow_gauge caminho Narrow gauge railway under construction  
light_rail caminho Light-railway under construction  
tram caminho Tramway under construction  
preserved caminho Preserved railway under construction e.g. for steam trains  
subway caminho Subway under construction  
monorail caminho 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.

Notes

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.


Future considerations

  • 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.
